Red Hat 4.8.5-16 Mysql 5.6.36

1 检查、删除已安装MySQL

# rpm 方式
[root@vultr ~]# rpm -qa | grep -i mysql
1) 如果有rpm包安装的MySQL，使用以下命令删除:
[root@vultr ~]# rpm -e --nodeps 包名
2) 查找之前老版本MySQL的目录，文件并且删除
[root@vultr ~]# find / -name mysql
[root@vultr ~]# rm -rf 目录
[root@vultr ~]# rm -rf /etc/my.cnf   # 需要手动删除my.cnf文件
3) 再次查找机器是否安装了MySQL
[root@vultr ~]# rpm -qa | grep -i mysql

2 检查、删除冲突软件

# mariadb
rpm -qa|grep mariadb
rpm -e --nodeps

3 检查、关闭进程

[root@linux ~]# ps -ef|grep mysql
root     27147 22596  0 14:47 pts/5    00:00:00 grep --color=auto mysqld
root     35193     1  0 May30 ?        00:01:29 bin/mysqld --user=root

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.

You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.

Also, the account for the anonymous user has been removed.

In addition, you can run:

  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test database.
This is strongly recommended for production servers.

See the manual for more instructions.

Please report any problems at http://bugs.mysql.com/

WARNING: Found existing config file /usr/my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used --defaults-file)
and when you later start the server.
The new default config file was created as /usr/my-new.cnf,
please compare it with your file and take the changes you need.
