启动mysql 报错：  
  
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)  
  
1、先查看 /etc/rc.d/init.d/mysqld status 看看m y s q l 是否已经启动.  
另外看看是不是权限问题.  
  
2、确定你的mysql.sock是不是在那个位置，  
mysql -u 你的mysql用户名 -p -S /var/lib/mysql/mysql.sock  
  
3、试试：service mysqld start  
  
4、如果是权限问题，则先改变权限 \#chown -R mysql:mysql /var/lib/mysql  
  
\[root@localhost ~\]\# /etc/init.d/mysqld start  
启动 MySQL： \[ 确定 \]  
\[root@localhost ~\]\# mysql -uroot -p  
  
   
  
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)  
   原因是，/var/lib/mysql 的访问权限问题。  
  
shell> chown -R mysql:mysql /var/lib/mysql  
  
接着启动服务器  
  
shell> /etc/init.d/mysql start  
  
服务器正常启动后察看 /var/lib/mysql 自动生成mysql.sock文件。  
  
但是我的问题仍然没有得到解决。  
  
问题终于解决：  
方法：    修改/etc/my.conf:  
\[mysqld\]  
datadir=/usr/local/mysql/data  
socket=/var/lib/mysql/mysql.sock  
  
\[mysql.server\]  
user=mysql  
basedir=/usr/local/mysql  
  
If there is not currently a section called \[client\], add one at the bottom of the file and copy the socket= line under the \[mysqld\] section such as:  
  
\[client\]  
socket=/var/lib/mysql/mysql.sock  
  
  
发现依旧如此，运行/etc/init.d/mysql start报错：    Starting MySQLCouldn't find MySQL manager or server  
是mysqld服务没启动，运行/usr/local/mysql/bin/mysqld\_safe &  
  
问题解决。
