导读：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

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.gz

tar xzvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz

mv mysql-5.7.21-linux-glibc2.12-x86_64 mysql

2.初始化mysql基础环境信息

vim /etc/profile

PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH

export PATH

export 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/mcdb

vi /usr/local/mysql/data/my.cnf

[client]

port = 3310

socket = /usr/local/mysql/data/mcdb/mysql.sock

[mysql]

no-auto-rehash

[mysqld]

user = mysql

port = 3310

socket = /usr/local/mysql/data/mcdb/mysql.sock

basedir = /usr/local/mysql

datadir = /usr/local/mysql/data

pid-file = /usr/local/mysql/data/mcdb/mysql.pid

relay-log = /usr/local/mysql/data/mcdb/relay-bin

relay-log-info-file = /usr/local/mysql/data/mcdb/relay-log.info

server-id = 12

[mysqld_safe]

log-error = /usr/local/mysql/data/mcdb/mysql.err

pid-file = /usr/local/mysql/data/mcdb/mysql.pid

4.新建用户

groupadd mysql

useradd mysql -g mysql

chown 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.cnf

mysqld_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;
