1.准备资源
虚拟机环境：VMware Workstation Pro、Centos7
官网下载mysql5.6.44:
点击下载

2.上传资源
第一步：上传软件包到linux操作系统，推荐使用xftp7
第二步：对mysql压缩包进行解压操作：tar.gz

# tar –zxf mysql-5.6.44-linux-glibc2.12-x86_64.tar.gz

第三步：移动mysql文件夹到/usr/local目录下并更名为mysql

# mv mysql-5.6.44-linux-glibc2.12-x86_64.tar /usr/local/mysql

3.安全设置
创建一个mysql用户并更改/usr/local/mysql目录权限（用户和组）

# useradd –r –s /sbin/nologin mysql

4.初始化数据库

[root@localhost /usr/local/mysql/] # scripts/mysql_install_db --user=mysql

初始化之前需要安装autoconf库【命令：yum-y install autoconf】

5.移除mariadb-libs库文件

[root@localhost /usr/local/mysql/] # yum remove mariadb-libs

6.移动support-files目录下的mysql.server脚本到/etc/init.d目录一份=>service

[root@localhost /usr/local/mysql/] # cp support-files/mysql.server /etc/init.d/mysql

7.启动mysql脚本

# service mysql start

8.设置密码并测试mysql数据库

# bin/mysqladmin -u root password 'root';
# bin/mysql -uroot -p 
Enter Password:root

9.mysql远程连接Navicate

授予其他用户访问权限：

mysql> grant all privileges on *.* to root@"%" identified by "root";
mysql> flush privileges;

10.配置my.conf配置,将/usr/local/mysql/support-files路径下的my-default.cnf复制到/etc/路径下并改名为my.cnf

# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

my.cnf简易配置：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
#[client]
#port = 3306
#socket = /usr/local/mysql/mysql.sock
[mysql]
default-character-set=utf8


[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
 basedir = /usr/local/mysql/
 datadir = /usr/local/mysql/data/
 port = 3306
 character-set-server=utf8
# server_id = .....
# socket = /usr/local/mysql/mysql.sock.

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M 

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

如果其中的#注释没有显示颜色效果，授予my.cnf具有644权限

# chmod 644 /etc/my.cnf 

其他操作：
拒绝远程连接：
回收权限：

Mysql>revoke all privileges,grant option from 'root'@”%”;
