2021-11-01 01:06:49

使用rpm安装MySQL的方法：首先下载rpm包，当然小编为大家准备好了rpm包，大家可以直接去下载，也可以自行去寻找合适的rpm包进行安装。

①rpm包下载

MySQL5.7.21 rpm包下载路径
无论是哪种方式下载的rpm包，接下来都需要上传到需要安装MySQL的服务器上，小编使用的是FileZilla工具进行上传文件到服务器。

等待文件上传完成之后，我们就需要进入到对应的上传目录下，进行安装。小编使用的是最粗暴的安装方式进行安装：

② rpm包安装

[root@admin01 2]# rpm -ivh *.rpm --nodeps --force
warning: mysql-community-client-5.7.21-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

可以看见上面的MySQL已经成功安装，MySQL的安装并不需要这么多的rpm包，大家也可以根据自已的需要选择需要的rpm包进行安装。

③ 启动MySQL

[root@admin01 ~]# systemctl status mysqld
● mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
   Active: active (running) since Mon 2021-11-22 08:36:35 EST; 19s ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
  Process: 2006 ExecStart=/usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid $MYSQLD_OPTS (code=exited, status=0/SUCCESS)
  Process: 1933 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS)
 Main PID: 2009 (mysqld)
   CGroup: /system.slice/mysqld.service
           └─2009 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid

Nov 22 08:36:21 admin01 systemd[1]: Starting MySQL Server...
Nov 22 08:36:35 admin01 systemd[1]: Started MySQL Server.

④修改my.cnf

默认MySQL的配置文件在/etc/my.cnf，找到该文件根据项目需要进行配置。修改完成后记得重启MySQL。

⑤获取MySQL的初始密码

[root@admin01 ~]# grep 'A temporary password' /data/mysql/mysqld.log | awk -F"root@localhost: " '{ print $2}' 
xdFqs#DE;3gx

⑥修改MySQL的密码

[root@admin01 ~]# mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.7.21-log
