如果你是使用mysql源码编辑方式安装的mysql，应该不会出现这个问题，如果你是用类似rpm模式安装的mysql，那么默认是不会安装rlm_sql_mysql.so的，如果需要这个文件就要补充安装mysql-devel-****.rpm

happy_liu thanks!

现在调试时遇到这个问题，应该怎么解决啊，mysqk\\\

其实网上大家问的最多的都是整个问题，说什么链接不到mysqld.sock，其实大家不妨看看mysql的错误日志就明白怎么回事，我这里的错误日志是在

/var/lib/mysql/*.err 你会发现mysql只所以不能启动，是因为/var/lib/mysql的权限不允许mysql服务访问，英文mysql默认是调用mysql用户来启动服务的，好了，既然知道是什么原因找到不能启动，那就简单了。我们只要

chown -R mysql:mysql /var/lib/mysql 就行，如果还是启动不了，再慢慢调试权限，反正一般启动不了都是权限的问题。

如果大家还是不能启动不了的话，那就用我的比较繁琐的权限的设置，反正我每次都是这么做的，一般不会有问题，见下：

chown -R root /usr/local/mysql
chgrp -R mysql /usr/local/mysql
chown -R root /usr/local/mysql/bin
chgrp -R mysql /usr/local/mysql/bin
chgrp -R mysql /var/lib/mysql
chmod 777 /var/lib/mysql
chown -R root /var/lib/mysql/mysql
chgrp -R mysql /var/lib/mysql/mysql
chmod 777 /var/lib/mysql/mysql
chown -R root /var/lib/mysql/mysql/*
chgrp -R mysql /var/lib/mysql/mysql/*
chmod 777 /var/lib/mysql/mysql/*
chmod 777 /usr/local/mysql/lib/mysql/libmysqlclient.a



做完上面的步骤，然后把你编译目录的一个脚本COPY过去

cp support-files/mysql.server /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

用ntsysv设置使mysql每次启动都能自动运行。

好了，至此mysql安装完毕，你可以这样起动你的mysql服务

/etc/rc.d/init.d/mysqld start
