RHEL5(CentOS)下nginx+php+mysql+tomcat+memchached配置全过程
一、准备工作：
SSH,telnet终端中文显示乱码解决办法
vi /etc/sysconfig/i18n
将内容改为
LANG="zh_CN.GB18030"
LANGUAGE="zh_CN.GB18030:zh_CN.GB2312:zh_CN"
SUPPORTED="zh_CN.GB18030:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="lat0-sun16"
二、安装PHP 5.2.10（FastCGI模式）
1、编译安装PHP 5.2.10所需的支持库：
tar zxvf libiconv-1.13.tar.gz
cd libiconv-1.13/
./configure --prefix=/usr/local
make
make install
cd ../
tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd http://www.cnblogs.com/
tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../
2、编译安装MySQL 5.1.38
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.38.tar.gz
cd mysql-5.1.38/
./configure --prefix=/usr/local/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=innobase
make && make install
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
cd ../
附：以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下两步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。
①、创建MySQL数据库存放目录
mkdir -p /data/mysql/data/
chown -R mysql:mysql /data/mysql/
②、以mysql用户帐号的身份建立数据表：
/usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data --user=mysql
③、创建my.cnf配置文件：
vi /data/mysql/my.cnf
输入以下内容：
引用
[client]
default-character-set = utf8
port = 3306
socket = /tmp/mysql.sock
[mysql]
prompt="(\u:www.xxx.com:)[\d]> "
no-auto-rehash
[mysqld]
#default-character-set = utf8
lower_case_table_names=1
user = mysql
port = 3306
socket = /tmp/mysql.sock
basedir = /usr/local/mysql
datadir = /data/mysql/data
open_files_limit = 10240
back_log = 600
max_connections = 3000
max_connect_errors = 6000
table_cache = 614
external-locking = FALSE
max_allowed_packet = 32M
sort_buffer_size = 2M
join_buffer_size = 2M
thread_cache_size = 300
thread_concurrency = 8
query_cache_size = 32M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
default_table_type = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M
max_heap_table_size = 246M
long_query_time = 1
log_long_format
log-bin = /data/mysql/binlog
binlog_cache_size = 4M
binlog_format = MIXED
max_binlog_cache_size = 8M
max_binlog_size = 512M
expire_logs_days = 7
key_buffer_size = 256M
read_buffer_size = 1M
read_rnd_buffer_size = 16M
bulk_insert_buffer_size = 64M
myisam_sort_buffer_size = 128M
myisam_max_sort_file_size = 10G
myisam_max_extra_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover
skip-name-resolve
master-connect-retry = 10
slave-skip-errors = 1032,1062,126,1114,1146,1048,1396
server-id = 1
innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 2048M
innodb_data_file_path = ibdata1:1024M:autoextend
innodb_file_io_threads = 4
innodb_thread_concurrency = 8
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 128M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
innodb_file_per_table = 0
[mysqldump]
quick
max_allowed_packet = 32M
直接杀掉mysql进程：killall -TERM mysqld
④、创建管理MySQL数据库的shell脚本：
vi /data/mysql/mysql
#!/bin/sh
mysql_port=3306
mysql_username="root"
mysql_password="xxx_dba"
function_start_mysql()
{
printf "Starting MySQL...\n"
/bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql/my.cnf 2>&1 > /dev/null &
}
function_stop_mysql()
{
printf "Stoping MySQL...\n"
/usr/local/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 5
function_start_mysql
}
function_kill_mysql()
{
kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')
}
if [ "$1" = "start" ]; then
function_start_mysql
elif [ "$1" = "stop" ]; then
function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
printf "Usage: /data/mysql/mysql {start|stop|restart|kill}\n"
fi
⑤、赋予shell脚本可执行权限：
chmod +x /data/mysql/mysql
⑥、启动MySQL：
/data/mysql/mysql start
⑦、通过命令行登录管理MySQL服务器（提示输入密码时直接回车）：
/usr/local/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
若出现问题：
ps -aux | grep mysql
mysql 1382 0.0 0.2 5544 1376 pts/0 S 17:34 0:00 bash
mysql 1475 0.0 0.2 5552 1388 pts/0 S 17:38 0:00 bash
# chown -R mysql:mysql /usr/local/mysql/
⑧、输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'xxx_dba';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY 'xxx_dba';
⑨、（可选）停止MySQL：
/data/mysql/mysql stop
3、编译安装PHP（FastCGI模式）
tar zxvf php-5.2.10.tar.gz
gzip -cd php-5.2.10-fpm-0.5.11.diff.gz | patch -d php-5.2.10 -p1
cd php-5.2.10/
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --without-pear
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/php/etc/php.ini
cd ../
curl http://pear.php.net/go-pear | /usr/local/php/bin/php
4、编译安装PHP5扩展模块
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../
tar jxvf eaccelerator-0.9.5.3.tar.bz2
cd eaccelerator-0.9.5.3/
/usr/local/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../
tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql
make
make install
cd ../
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../
tar zxvf imagick-2.2.2.tgz
cd imagick-2.2.2/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../
5、修改php.ini文件
手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./"
修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行，然后保存：
extension = "memcache.so"
extension = "pdo_mysql.so"
extension = "imagick.so"
再查找output_buffering = Off
修改为output_buffering = On
自动修改：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php.ini文件的修改：
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/php/etc/php.ini
6、配置eAccelerator加速PHP：
mkdir -p /usr/local/eaccelerator_cache
vi /usr/local/php/etc/php.ini
按shift+g键跳到配置文件的最末尾，加上以下配置信息：
[eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
7、创建www用户和组，以及虚拟主机使用的目录：
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data/htdocs/group
chmod +w /data/htdocs/group
chown -R www:www /data/htdocs/group
8、创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：
在/usr/local/php/etc/目录中创建php-fpm.conf文件：
rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/php/etc/php-fpm.conf
输 入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）：
<?xml version="1.0" ?>

9、启动php-cgi进程，监听127.0.0.1的9000端口，进程数为200（如果服务器内存小于3GB，可以只开启64个进程），用户为www：
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
注：/usr/local/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。
注 意：此处启动时遇到了麻烦， 启动警告：libgomp.so.1: shared object cannot be dlopen()ed in Unknown on line 0，经过百度，有人说是gcc版本太低，我可能了下我的GCC版本是4.1.1 20070105。
升级GCC
三、安装Nginx 0.8.15
1、安装Nginx所需的pcre库：
tar zxvf pcre-7.9.tar.gz
cd pcre-7.9/
./configure
make && make install
cd ../
2、安装Nginx
tar zxvf nginx-0.8.15.tar.gz
cd nginx-0.8.15/
加入SSL模块、FLV模块、清楚制定URL缓存
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --add-module=../ngx_cache_purge-1.0
make && make install
cd ../
3、创建Nginx日志目录
mkdir -p /data/logs
chmod +w /data/logs
chown -R www:www /data/logs
4、创建Nginx配置文件
①、在/usr/local/nginx/conf/目录中创建nginx.conf文件：
cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.default.conf
rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf
输入以下内容：
user www www;
worker_processes 8;
error_log /data/logs/nginx_error.log crit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;

}
server
{
listen 80;
server_name status.xxx.cn;
location / {
stub_status on;
access_log off;
}
}
}
②、在/usr/local/nginx/conf/目录中创建fcgi.conf文件：
vi /usr/local/nginx/conf/fcgi.conf
输入以下内容：
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
5、启动Nginx
ulimit -SHn 65535
/usr/local/nginx/sbin/nginx
四、配置开机自动启动Nginx + PHP
vi /etc/rc.local
在末尾增加以下内容：
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx
五、优化Linux内核参数
vi /etc/sysctl.conf
在末尾增加以下内容：
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535
使配置立即生效：
/sbin/sysctl -p
六、在不停止Nginx服务的情况下平滑变更Nginx配置
1、修改/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：
/usr/local/nginx/sbin/nginx -t
如果屏幕显示以下两行信息，说明配置文件正确：
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
2、这时，输入以下命令查看Nginx主进程号：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
屏幕显示的即为Nginx主进程号，例如：
6302
这时，执行以下命令即可使修改过的Nginx配置文件生效：
kill -HUP 6302
或者无需这么麻烦，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/nginx/nginx.pid`
0.8以后的产品
/usr/local/nginx/sbin/nginx -s reload
七、编写每天定时切割Nginx日志的脚本
1、创建脚本/usr/local/nginx/sbin/cut_nginx_log.sh
vi /usr/local/nginx/sbin/cut_nginx_log.sh
输入以下内容：
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/usr/local/nginx/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`
2、设置crontab，每天凌晨00:00切割nginx访问日志
crontab -e
输入以下内容：
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh
八、安装JDK+TOMCAT
1、安装JDK
#chmod +X jdk-6u18-ea-bin-b05-linux-i586-18_nov_2009.bin
# ./jdk-6u18-ea-bin-b05-linux-i586-18_nov_2009.bin
# mv jdk1.6.0.18 /usr/local/jdk
2、配置环境变量
# vi /etc/profile
按shift+g，将下面这段文字加到结尾
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$CLASSPATH
export PATH=$PATH:$JAVA_HOME/jre/bin
export CATALINA_HOME=/usr/local/tomcat
wq退出
3、让配置立即启用
source /etc/profile
九、安装TOMCAT
# tar zxvf apache-tomcat-6.0.26.tar.gz
# mv apache-tomcat-6.0.26 /usr/local/tomcat
十：配置nginx.conf：
vi /usr/local/nginx/conf/nginx.conf
user www www;
worker_processes 8;
error_log /data/logs/nginx_error.log crit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.

十一、安装memcached
首先安装 memcache 的时候缺少 libevent。还是先安装好 libevent， 下载libevent：http://www.monkey.org/~provos/libevent-1.4.9-stable.tar.gz。
[root@master chenlb]# wget http://www.danga.com/memcached/dist/memcached-1.2.6.tar.gz
[root@master chenlb]# tar zxvf memcached-1.2.6.tar.gz
[root@master chenlb]# cd memcached-1.2.6
[root@master memcached-1.2.6]# ./configure --prefix=/usr/local/memcache --with-libevent=/usr/local
[root@master memcached-1.2.6]# make
[root@master memcached-1.2.6]# make install
接着运行：
1. [root@master memcached-1.2.6]# /usr/local/memcached/bin/memcached -d -m 10 -p 11211 -u root
2. /usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory
[root@master memcached-1.2.6]# /usr/local/memcached/bin/memcached -d -m 10 -p 11211 -u root
/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory
报错说：libevent-1.4.so.2 不在公共文件里。郁闷，然后打到 芽雨快跑 的 blog。解决方法是链接一下。
1. [root@master memcached-1.2.6]# ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib/libevent-1.4.so.2
2. [root@master memcached-1.2.6]# /usr/local/memcached/bin/memcached -d -m 10 -p 11211 -u root
十二、创建数据库用户并赋权：
GRANT SELECT , INSERT , UPDATE , DELETE , CREATE , DROP , INDEX , ALTER , CREATE TEMPORARY TABLES , CREATE VIEW , SHOW VIEW , CREATE FUNCTION,CREATE PROCDURE, CREATE ROUTINE, ALTER ROUTINE, EXECUTE ON dotayo_db.* TO 'dotayo_db'@'192.168.1.%' IDENTIFIED BY 'dotayo_db';
十三、从开发机复制数据库实例到测试机，若有函数或存储过程，需设置：
mysql> SET GLOBAL log_bin_trust_function_creators = 1;
Query OK, 0 rows affected (0.00 sec)
已管理员账号登陆SQLyog，连接开发数据库与测试数据库，copy完成，数据库搭建完成。
十四：启动tomcat，OutOfMemoryError: PermGen space
解决办法：
以下给出2G内存环境下java jvm 的参数设置参考：
vi /usr/local/tomcat/bin/catalina.sh
在“echo "Using CATALINA_BASE: $CATALINA_BASE"”上面加入以下行：
JAVA_OPTS="-server -Xms800m -Xmx800m -XX:PermSize=128M -XX:MaxNewSize=512m -XX:MaxPermSize=256m -Djava.awt.headless=true "
重启tomcat
十五、配置iptables:
#vi /etc/sysconfig/iptables
文件内容
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]

COMMIT
至此，服务器配置全部完成，以上配置参考了一些牛人的文档！
注意事项：
压缩解压缩文件
用户用mydir目录中最近被修改或添加的文件来对myarch.tar文件进行更新。
#tar uf myarch.tar mydir
#tar zxvf myarch.tar
如果你安装了某些库，比如在安装gtk -2.4.13时它会需要glib-2.0 >= 2.4.0,辛苦的安装好glib后
没有指定 --prefix=/usr 这样glib库就装到了/usr/local下，而又没有在/etc/ld.so.conf中添加/usr/local/lib
这个搜索路径，所以编译gtk -2.4.13就会出错了
