 Centos7安装mysql5.7解压版完整教程避免踩坑，可以把数据目录和系统目录分开设置。 1、卸载Centos7默认自带的mariadb数据库，避免冲突代码语言：javascript复制#先查询是否安装，找到已安装的对应mariadb， yum list installed |grep mariadb #列表展示的是mariadb-libs.x86_64 ，执行如下命令进行安装 yum remove mariadb-libs.x86_64 2、下载解压版mysql并安装下载mysql5.7解压版，我下载的版本mysql-5.7.33-linux-glibc2.12-x86_64.tar.gz  代码语言：javascript复制#创建MySQL上传目录
mkdir /opt/tools
#然后登录Linux服务器，将下载好的安装包上传到服务器的/opt/tools目录。执行解压命令
cd /opt/tools
tar -zxf /data/tools/mysql-5.7.33-linux-glibc2.12-x86_64.tar.gz
#解压后的目录改名
mv mysql-5.7.27-linux-glibc2.12-x86_64 mysql
#移动mysql到 /usr/local/mysql
mv mysql-5.7.27-linux-glibc2.12-x86_64 /usr/local/mysql
cd /usr/local/mysql
#创建用户组和用户 mysql
groupadd mysql
useradd -r -g mysql mysql
#目录授权
chgrp -R mysql .
chown -R mysql .
#创建MySQL存储数据的目录
mkdir /data/mysql/data
mkdir /data/mysql/share
进入bin目录执行初始化
cd /usr/local/mysql/bin
./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/data/mysql/data/ --lc_messages_dir=/data/mysql/share --lc_messages=en_US注意：执行完成后输出的内容最后一行是数据库root的密码，一定要先保存下来  图片进入support-files,修改mysql.server cd /usr/local/mysql/support-files 代码语言：javascript复制#!/bin/sh # Copyright Abandoned 1996 TCX DataKonsult AB & Monty Program KB & Detron HB # This file is public domain and comes with NO WARRANTY of any kind # MySQL daemon start/stop script. # Usually this is put in /etc/init.d (at least on machines SYSV R4 based # systems) and linked to /etc/rc3.d/S99mysql and /etc/rc0.d/K01mysql. # When this is done the mysql server will be started when the machine is # started and shut down when the systems goes down. # Comments to support chkconfig on RedHat Linux # chkconfig: 2345 64 36 # description: A very fast and reliable SQL database engine. # Comments to support LSB init script conventions ### BEGIN INIT INFO # Provides: mysql # Required-Start: $local_fs $network $remote_fs # Should-Start: ypbind nscd ldap ntpd xntpd # Required-Stop: $local_fs $network $remote_fs # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: start and stop MySQL # Description: MySQL is a very fast and reliable SQL database engine. ### END INIT INFO # If you install MySQL on some other places than /usr/local/mysql, then you # have to do one of the following things for this script to work: # # - Run this script from within the MySQL installation directory # - Create a /etc/my.cnf file with the following information: # [mysqld] # basedir= # - Add the above to any other configuration file (for example ~/.my.ini) # and copy my_print_defaults to /usr/bin # - Add the path to the mysql-installation-directory to the basedir variable # below. # # If you want to affect other MySQL variables, you should make your changes # in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files. # If you change base dir, you must also change datadir.
