注意 Can‘t start server : Bind on unix socket: Permission denied
发现 /var/lib/mysql 目录下并没有生成mysql.sock 预计是权限问题
于是修改
[root@fjgh ~]# chmod 777 /var/lib/mysql [root@fjgh ~]# service mysqld start Starting MySQL.. SUCCESS!
启动成功
突然又发现 mysql -v 执行出差
[root@fjgh bin]# mysql -v
-bash: msysql: command not found
查看环境变量配置
[root@fjgh bin]# echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/java/jdk1.8.0_212/bin:/root/bin:/usr/local/mysql-5.5.60/bin
发现配置的mysql的bin目录不对，应该是 /usr/local/mysql-5.5.62/bin
修改，刷新配置即可
[root@fjgh bin]# echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/java/jdk1.8.0_212/bin:/root/bin:/usr/local/mysql-5.5.60/bin [root@fjgh bin]# source ~/.bash_profile [root@fjgh bin]# echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/java/jdk1.8.0_212/bin:/root/bin:/usr/local/mysql-5.5.60/bin:/root/bin:/usr/local/mysql-5.5.62/bin
