Liunx环境下登录mysql8报错

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

1.TCP 连接(如果报错 /tmp/mysql.sock，你可以尝试这种方式连接)

mysql -uroot -h 127.0.0.1 -p

2.socket 连接

mysql -uroot -p

解决方式：

添加 [client] 配置项，如下所示

[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

配置后：(配置 [client] 后，重启 mysql服务)

[mysqld]
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
socket=/var/lib/mysql/mysql.sock（跟这个socket路径一样）
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[client]
port=3306
socket=/var/lib/mysql/mysql.sock
