linux下MYSQL常见两个错误的解决办法_MySQL

问题1：登录mysql的错误

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

解决方法：

1)默认的mysql.sock文件是在/tmp目录下。
2)我们建立一个软连接，ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

问题2：Timeout error occurred trying to start MySQL Daemon.
#/etc/init.d/mysqld restart
stopping mysql [ok]
Timeout error occurred trying to start MySQL Daemon. [failure]
但是这个时候mysql实际上已经起动了,因为用netstat -ln命令去看3306端口已经起动.使用mysql -u root -p password也能连接到数据库.

解决方法：

修改/etc/init.d/mysqld.
在mysql里创建dameon用户,然后再修改/etc/init.d/mysqld.

具体操作如下：

我们不妨先看看/etc/init.d/mysqld起动脚本是如何工作的,注意下面的一段

# If you've removed anonymous users, this line must be changed to

# use a user that is allowed to ping mysqld.

ping=”/usr/bin/mysqladmin -uUNKNOWN_MYSQL_USER ping”

# Spin for a maximum of ten seconds waiting for the server to come up

if [ $ret -eq 0 ]; then

for x in 1 2 3 4 5 6 7 8 9 10; do

if [ -n “`$ping 2> /dev/null`” ]; then

break;

else

sleep 1来@源gao*daima.com搞@代#码网;

fi

done

if !([ -n “`$ping 2> /dev/null`” ]); then

echo “Timeout error occurred trying to start MySQL
