[root@ bin]# Logging to '/usr/local/mysql/data/1111.err'.
--19T21::.875454Z mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

停留是正常的，这是启动成功了。

[root@localhost bin]# 2019-03-15T18:51:18.777280Z mysqld_safe Logging to '/var/log/mysqld.log'.
2019-03-15T18:51:18.780334Z mysqld_safe Directory '/var/lib/mysql' for UNIX socket file don't exists.

这个报错，就删掉/etc/my.cnf再重新启动

　　

ln -s /usr/local/mysql/bin/mysql /usr/bin 创建链接 、改密码： mysql> ALTER USER USER() IDENTIFIED BY 'root123'; （修改密码）
