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 --2019-05-04 07:00:43-- http://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm Resolving repo.mysql.com (repo.mysql.com)... 23.41.23.231 Connecting to repo.mysql.com (repo.mysql.com)|23.41.23.231|:80... connected.

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

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. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. 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。
