为什么80%的码农都做不了架构师？>>> 
问题1：
再次./configure以下错误发生
configure: error: xml2-config not found. Please check your libxml2 installation.
解决方法：
安装libxml2
# yum install libxml2-devel
问题2：
hecking libxml2 install dir... no
checking for xml2-config path... /usr/bin/xml2-config
checking whether libxml build works... no
configure: error: build test failed. Please check the config.log for details.
解决方法：
# yum erase zlib-devel
# yum install zlib-devel
# yum install libxml2-devel

测试Mysqli运行状况：
$mysqli = new mysqli("localhost", "my_user", "my_password", "dbname");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
configure: error: libjpng.(a|so) not found
其实也是和刚才的一样.
cp -frp /usr/lib64/libpng* /usr/lib/
