篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了CentOS下yum安装mysql相关的知识,希望对你有一定的参考价值。

  其实跟windows下安装过程差别不大,就是下载为了方便使用了yum的方式。安装前先确认下系统是否还安装mysql,卸载是否不完全,再去官网(http://dev.mysql.com/downloads/repo/yum/)选一个yum版本,这里我选了最新的mysql80-community-release-el7-3.noarch.rpm,通过wget下载后就可以安装mysql服务端了,然后就算完了。是不是很简单?当然为了使用方便,跟windows的一样,最好再改下初始密码。下面看下操作记录:

1、检查下是否已下载还有卸载残留

# rpm -qa | grep mysql
# find / -name mysql /etc/selinux/targeted/active/modules/100/mysql /usr/lib64/mysql /usr/share/mysql

  看来还是有的,通过rm -rf将以上目录删掉即可,另外顺便把配置文件/etc/my.cnf也删掉吧,用rm -f。

2、安装yum

# wget http://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm

3、安装mysql

# sudo rpm -Uvh mysql80-community-release-el7-3.noarch.rpm

  上面的安装过程有点长,可以看到它默认给我们安装了最新版本的mysql8,当然你也可以自己指定版本。另外它在安装时会去删掉原有的卸载残留,不过因为我们已经提前删掉了,所以会出现那一堆warnning提示删除卸载残留文件时没找到文件。

4、启动mysql

# service mysqld start
Redirecting to /bin/systemctl start mysqld.service
# service mysqld status
Redirecting to /bin/systemctl status mysqld.service
鈼[0m mysqld.service - MySQL Server
   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
   Active: active (running) since Sat 2019-05-04 07:10:32 CST; 15s ago
     Docs: man:mysqld(8)
           http://dev.mysql.com/doc/refman/en/using-systemd.html
  Process: 11678 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS)

   CGroup: /system.slice/mysqld.service
           鈹斺攢11772 /usr/sbin/mysqld

May 04 07:10:18 VM_0_17_centos systemd[1]: Starting MySQL Server...
May 04 07:10:32 VM_0_17_centos systemd[1]: Started MySQL Server.

5、找初始密码

# grep temporary password /var/log/mysqld.log 
2019-05-03T23:10:26.160286Z 5 [Note] [MY-010454] [Server] A temporary password is generated for [email protected]: c-uo(;XAc2FD

  这里的c-uo(;XAc2FD就是我的初始密码,复制它去登陆mysql。

6、登陆并修改密码

# mysql -uroot -p 
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.0.16

Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.

Type help; or \h for help. Type \c to clear the current input statement.
mysql> ALTER USER root@localhost IDENTIFIED BY [email protected];
Query OK, 0 rows affected (0.03 sec)

  这里说下密码规则:8位以上,大小写字母、数字和特殊字母。

7、创建个新库来用:

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
4 rows in set (0.00 sec)

mysql> create database test;
Query OK, 1 row affected (0.03 sec)

mysql> use test;
Database changed
mysql> show tables;
Empty set (0.00 sec)

8、重启mysql,使用新密码登陆,开始接入应用

# service mysqld restart
Redirecting to /bin/systemctl restart mysqld.service

  这里我是给安装mysql的机器自己用的,所以没有开发端口给远程。需要本地远程机器的话还得再设置一下,这里就不展开了。
