1、環(huán)境說明

操作系統(tǒng)：centos7.5

MySQL版本：mysql5.6

2、具體步驟

1.官網(wǎng)(https://dev.mysql.com/downloads/mysql/)下載mysql5.6.46安裝包

3.目錄重命名

mv mysql-5.6.46-linux-glibc2.12-x86_64 /usr/local/mysql5.6

4.創(chuàng)建mysql用戶和組

執(zhí)行：/usr/local/mysql5.6/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql5.6 --datadir=/usr/local/mysql5.6/data

7.復制mysql配置文件

cd /usr/local/mysql5.6/support-files

cp my-default.cnf /etc/my.cnf

cp mysql.server /etc/init.d/mysql

chkconfig mysql on

9.添加環(huán)境變量

vi /etc/profile

在最下面添加

export MYSQL_HOME=/usr/local/mysql5.6

export PATH=$PATH:$MYSQL_HOME/bin

保存退出后，執(zhí)行生效代碼

source /etc/profile

10.設置默認端口

[mysqld]

basedir=/usr/local/mysql5.6

datadir=/usr/local/mysql5.6/data

port=3306

server_id=1

socket=/tmp/mysql.sock

11.編輯mysql啟動腳本

vi /etc/init.d/mysql

basedir=/usr/local/mysql5.6

datadir=/usr/local/mysql5.6/data
