服务器环境：
CentOS-7.4-x86_64-DVD-1708
MySQL版本：
mysql-5.7.27-linux-glibc2.12-x86_64.tar.gz
1，首先卸载Centos7自带的Mariadb
# 查看系统自带的Mariadb
[root@CDH-141 ~]# rpm -qa|grep mariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64
# 卸载系统自带的Mariadb(此时要根据实际情况去卸载)
[root@CDH-141 ~]# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64
2，检查Msyql是否存在
# 检查mysql是否存在
[root@CDH-141 ~]# rpm -qa | grep mysql
[root@CDH-141 ~]# 3，查看用户和组是否存在
(1),先检查是否存在，如果不存在则创建
# 检查mysql组和用户是否存在，如无则创建
[root@CDH-141 ~]# cat /etc/group | grep mysql
[root@CDH-141 ~]# cat /etc/passwd | grep mysql # 创建mysql用户组
[root@CDH-141 ~]# groupadd mysql
# 创建一个用户名为mysql的用户，并加入mysql用户组
[root@CDH-141 ~]# useradd -g mysql mysql
# 制定password 为111111
[root@CDH-141 ~]# passwd mysql
Changing password for user mysql.
New password:
BAD PASSWORD: The password is a palindrome
Retype new password:
passwd: all authentication tokens updated successfully.4，下载mysql离线安装包tar文件
官网下载地址：https://dev.mysql.com/downloa...
版本选择，可以选择一下两种方式：
1）使用Red Hat Enterprise LinuxSelect Version:5.7.25Select Operating System:Red Hat Enterprise Linux / Oracle LinuxSelect OS Version:Red Hat Enterprise Linux 7 / Oracle Linux 7 (x86, 64-bit)列表中下载：Compressed TAR Archive：(mysql-5.7.25-el7-x86_64.tar.gz)
2）使用Linux - GenericSelect Version:5.7.25Select Operating System:Linux - GenericSelect OS Version:Linux - Generic (glibc 2.12) (x86, 64-bit)列表中下载：Compressed TAR Archive：(mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz)【本文中使用的是这个版本】注意：上边两种方式找mysql离线安装包的方式都可以。
5，上传第四步下载的mysql TAR包
# 上传mysql TAR包
# 或者直接使用XFTP进行安装

[root@CDH-141 mysql]#11，修改环境变量配置文件
# 进入/etc/profile文件夹
[root@CDH-141 mysql]# vi /etc/profile
修改/etc/profile，在最后添加如下内容
# 修改/etc/profile文件
export MYSQL_HOME=/usr/local/mysql
export PATH=$MYSQL_HOME/bin:$PATH
# 使文件生效
[root@CDH-141 mysql]# source /etc/profile12，获得MySQL初始密码
# 每个人的密码是不一样的，随机生成的
[root@CDH-141 mysql]# cat /root/.mysql_secret
# Password set for user 'root@localhost' at 2019-03-08 17:40:42
poc3u0mO_luv
[root@CDH-141 mysql]# 13，修改密码

mysql> 14，添加远程访问权限
注意：当前的访问权限是直接给root用户添加的，如果在项目现场部署的时候，是不能使用root用户的;
此时是有两种方案的，分别做了整理：
## 方案1：直接给root用户增加远程访问权限
# 添加远程访问权限
mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> update user set host='%' where user='root';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select host,user from user;
+-----------+---------------+
| host | user |
+-----------+---------------+
| % | root |
| localhost | mysql.session |
| localhost | mysql.sys |
+-----------+---------------+
3 rows in set (0.00 sec)
mysql>--- 方案2：追加一个demo用户，然后给demo用户添加远程访问的权限
mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
-- 此时是给所有用户开放的，如果需要对不不同的用户开发需要再单独设置
mysql> update user set host='%' where user='demo';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select host,user from user;
+-----------+---------------+
| host | user |
+-----------+---------------+
| % | demo |
| localhost | mysql.session |
| localhost | mysql.sys |
+-----------+---------------+
3 rows in set (0.00 sec)15，重启MySQL使其生效
做上述操作之后，是需要重新启动MySQL，才能使其生效
# 重启mysql
[root@CDH-141 mysql]# /etc/init.d/mysqld restart
Shutting down MySQL..[ OK ]
Starting MySQL..[ OK ]
[root@CDH-141 mysql]#
## 重启命令2
systemctl start mysql16，如果连接失败，需要检查防火墙
# 第一步：关闭防火墙
systemctl stop firewalld#################
#############
####### 注意，在实际中先关闭，确定是使用开发端口的方式实现，还是直接移除，再执行对应的操作
##### 第二步：此时有两种解决方案
# 方案1：移除防火墙
systemctl disable firewalld
# 方案2：开发3306端口
# 开放端口请根据实际访问规则配置，这里只是单纯开启3306端口的访问，默认全放行，在生产环境禁止开放所有IP访问
# (1) 向防火墙添加 mysql 端口:
firewall-cmd --zone=public --add-port=3306/tcp --permanent
# (2) 刷新防火墙规则:
firewall-cmd --reload
# (3) 验证端口,查询防火墙开放端口:
firewall-cmd --zone=public --list-port转载自:https://segmentfault.com/a/1190000041667595
