mysql5.7如何安裝部署、初始化和創(chuàng)建實(shí)例方法介紹

本文主要給大家介紹mysql5.7如何安裝部署、初始化和創(chuàng)建實(shí)例方法，文章內(nèi)容都是筆者用心摘選和編輯的，具有一定的針對性，對大家的參考意義還是比較大的，下面跟筆者一起了解下mysql5.7如何安裝部署、初始化和創(chuàng)建實(shí)例方法吧。 

很簡單的流程

環(huán)境信息：
centos 7.2
mysql 5.7.21

1.下載解壓縮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基礎(chǔ)環(huán)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.初始化配置實(shí)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.新建用戶

groupadd mysql
useradd mysql -g mysql
chown mysql:mysql /usr/local/mysql -R

5.初始化mysql實(shí)例
mysqld --initialize --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/mcdb --user=mysql
從返回信息最后一行獲得密碼，舉個(gè)栗子：
yUlta1lw*uwF

6.移動配置文件到實(shí)例目錄，啟動該實(shí)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.登錄mysql
mysql -uroot -pyUlta1lw*uwF -S /usr/local/mysql/data/mcdb/mysql.sock

8.設(shè)定密碼

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

9.創(chuàng)建用戶并開放遠(yuǎn)程登錄權(quán)限
grant all privileges on *.* to 'bodie'@'%' identified by 'happybirthday' with grant option;
