禅道安装界面提示PDO_Mysql扩展和Session存储目录检查失败

1、重新编译php
添加--with-pdo-mysql=/usr/local/mysql指定MySQL的安装目录
编译时会报：
/home/oldboy/tools/php-5.3.27/sapi/cli/php: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

make: *** [ext/phar/phar.php] 错误 127

报错：

解决1：

[[email protected] php-5.3.27]# find / -name "libmysqlclient.so.18"

/home/oldboy/tools/mysql-5.5.32-linux2.6-x86_64/lib/libmysqlclient.so.18

/application/mysql-5.5.32/lib/libmysqlclient.so.18

[[email protected] php-5.3.27]# echo "/usr/local/lib" >>/etc/ld.so.conf

[[email protected] php-5.3.27]# echo "/application/mysql-5.5.32/lib" >>/etc/ld.so.conf

[[email protected] php-5.3.27]# tail -1 /etc/ld.so.conf

/application/mysql-5.5.32/lib

[[email protected] php-5.3.27]# ldconfig

2、在php.ini配置文件添加参数
session.save_path = "/var/lib/php/session"
需要创建目录/var/lib/php/session。
命令为：
mkdir -p /var/lib/php/session
需要修改目录 "/var/lib/php/session" 的权限。
命令为：
chmod o=rwx -R /var/lib/php/session
