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

<style></style>

我在源码编译安装mysql后,虽然mysql服务可以正常启动,但是当我直接执行mysql后,出现了错误。

错误提示如下:

[root@server98 ~]# mysql

ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/tmp/mysql.sock‘ (2)


出现错误原因:

由于mysql默认的mysql.sock是在/var/lib/mysql/mysql.sock,但linux系统总是去/tmp/mysql.sock查找,所以会报错。

[root@server98 ~]# find / -namemysql.sock

/usr/local/mysql/data/mysql.sock


解决方法如下:
1.直接指定mysql通道

[root@server98 ~]# mysql--socket=/usr/local/mysql/data/mysql.sock

2.创建符号链接(软链接)

mysql.sock增加软链接(相当与Windows下的快捷方式)

[root@server98 tmp]#ln -s/usr/local/mysql/data/mysql.sock /tmp/mysql.sock


[root@server98 ~]# mysql
