致敬J哥

1.解压及创建目录

[root@hadoop ~]# cd /usr/local/

[root@hadoop local]# tar -xvf /home/hadoop/software/mysql-5.7.26-el7-x86_64.tar.gz -C /usr/local/

[root@hadoop local]# mv mysql-5.7.26-el7-x86_64 mysql

[root@hadoop local]# mkdir mysql/arch mysql/data mysql/tmp

2.创建my.cnf(见文件)

[root@hadoop local]# cp /etc/my.cnf my.cnf.bak

[root@hadoop local]# vi /etc/my.cnf

# 先清空文件

# Try number of CPU's*2 for thread_concurrency

3.创建用户组及用户

[root@hadoop local]# groupadd -g 101 mysql

[root@hadoop local]# useradd -u 514 -g mysql -G root -d /usr/local/mysql mysqladmin

useradd：警告：此主目录已经存在。

不从 skel 目录里向其中复制任何文件。

[root@hadoop local]# id mysqladmin

uid=514(mysqladmin) gid=101(mysql) 组=101(mysql),0(root)

## 一般不需要设置mysqladmin的密码，直接从root或者LDAP用户sudo切换

#[root@hadoop local]# passwd mysqladmin

Changing password for user mysqladmin.

New UNIX password:

BAD PASSWORD: it is too simplistic/systematic

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

## if user mysqladmin is existing,please execute the following command of usermod.

#[root@hadoop local]# usermod -u 514 -g mysql -G root -d /usr/local/mysql mysqladmin

4.copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量

[root@hadoop local]# cp /etc/skel/.* /usr/local/mysql ###important

5.配置环境变量

[root@hadoop local]# vi mysql/.bashrc

# .bashrc

# Source global definitions

if [ -f /etc/bashrc ]; then

. /etc/bashrc

# Uncomment the following line if you don't like systemctl's auto-paging feature:

# export SYSTEMD_PAGER=

# User specific aliases and functions

export MYSQL_BASE=/usr/local/mysql

export PATH=${MYSQL_BASE}/bin:$PATH

unset USERNAME

#stty erase ^H

set umask to 022

umask 022

PS1=`uname -n`":"'$USER'":"'$PWD'":>"; export PS1

## end

6.赋权限和用户组，切换用户mysqladmin，安装

[root@hadoop local]# chown mysqladmin:mysql /etc/my.cnf

[root@hadoop local]# chmod 640 /etc/my.cnf

[root@hadoop local]# chown -R mysqladmin:mysql /usr/local/mysql

[root@hadoop local]# chmod -R 755 /usr/local/mysql

7.配置服务及开机自启动

[root@hadoop local]# cd /usr/local/mysql

#将服务文件拷贝到init.d下，并重命名为mysql

[root@hadoop mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql

#赋予可执行权限

[root@hadoop mysql]# chmod +x /etc/rc.d/init.d/mysql

#删除服务

[root@hadoop mysql]# chkconfig --del mysql

#添加服务

[root@hadoop mysql]# chkconfig --add mysql

[root@hadoop mysql]# chkconfig --level 345 mysql on

[root@hadoop mysql]# vi /etc/rc.local

#!/bin/sh

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

su - mysqladmin -c "/etc/init.d/mysql start --federated"

"/etc/rc.local" 9L, 278C written

8.安装libaio及安装mysql的初始db

[root@hadoop mysql]# yum -y install libaio

[root@hadoop mysql]# sudo su - mysqladmin

hadoop:mysqladmin:/usr/local/mysql:>bin/mysqld \

--defaults-file=/etc/my.cnf \

--user=mysqladmin \

--basedir=/usr/local/mysql/ \

--datadir=/usr/local/mysql/data/ \

--initialize

在初始化时如果加上 –initial-insecure，则会创建空密码的 root@localhost 账号，否则会创建带密码的 root@localhost 账号，密码直接写在 log-error 日志文件中

（在5.6版本中是放在 ~/.mysql_secret 文件里，更加隐蔽，不熟悉的话可能会无所适从）

9.查看临时密码

hadoop:mysqladmin:/usr/local/mysql:>cd /usr/local/mysql/data

hadoop:mysqladmin:/usr/local/mysql/data:>cat hostname.err |grep password

2020-06-04T11:03:30.466803Z 1 [Note] A temporary password is generated for root@localhost: <7pYz++t#p:5

10.启动

hadoop:mysqladmin:/usr/local/mysql/data:>/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

11.登录及修改用户密码

hadoop:mysqladmin:/usr/local/mysql/bin:>cd /usr/local/mysql/bin

hadoop:mysqladmin:/usr/local/mysql/bin:>mysql -uroot -p'<7pYz++t#p:5'

12.重启

hadoop:mysqladmin:/usr/local/mysql/bin:>service mysql restart
