很简单的流程

环境信息：
centos 7.2
mysql 5.7.21

1.下载解压缩mysql包

cd /usr/local/wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gztar xzvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gzmv mysql-5.7.21-linux-glibc2.12-x86_64 mysql

2.初始化mysql基础环境信息

vim /etc/profilePATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATHexport PATHexport MYSQL_HOME="/usr/local/mysql"export ms="/usr/local/mysql"

3.初始化配置实例配置文件

mkdir -p /usr/local/mysql/data/mcdbvi /usr/local/mysql/data/my.cnf

[client]port = 3310socket = /usr/local/mysql/data/mcdb/mysql.sock[mysql]no-auto-rehash[mysqld]user = mysqlport = 3310socket = /usr/local/mysql/data/mcdb/mysql.sockbasedir = /usr/local/mysqldatadir = /usr/local/mysql/datapid-file = /usr/local/mysql/data/mcdb/mysql.pidrelay-log = /usr/local/mysql/data/mcdb/relay-binrelay-log-info-file = /usr/local/mysql/data/mcdb/relay-log.infoserver-id = 12[mysqld_safe]log-error = /usr/local/mysql/data/mcdb/mysql.errpid-file = /usr/local/mysql/data/mcdb/mysql.pid

4.新建用户

groupadd mysqluseradd mysql -g mysqlchown mysql:mysql /usr/local/mysql -R

5.初始化mysql实例
mysqld --initialize --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mcdb --user=mysql
从返回信息最后一行获得密码，举个栗子：
yUlta1lw*uwF

6.移动配置文件到实例目录，启动该实例mysql

mv /usr/local/mysql/data/my.cnf /usr/local/mysql/data/mcdb/my.cnfmysqld_safe --defaults-file=/usr/local/mysql/data/mcdb/my.cnf --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mcdb &

7.登录mysql
mysql -uroot -pyUlta1lw*uwF -S /usr/local/mysql/data/mcdb/mysql.sock

8.设定密码

mysql> SET PASSWORD = PASSWORD('hello2018'); mysql> flush privileges;

9.创建用户并开放远程登录权限
grant all privileges on *.* to 'bodie'@'%' identified by 'happybirthday' with grant option;
