Error when logging into mysql8 under Liunx environment

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

1.TCP connection (if an error is reported /tmp/mysql.sock, you can try to connect in this way)

mysql -uroot -h 127.0.0.1 -p

2.socket connection

mysql -uroot -p

Solution:

Add the [client] configuration item as shown below

[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

After configuration: (After configuring [client], restart the mysql service)

[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
