#移动MySQL程序到安装目录下
[root@db04 tools]# mv mysql-5.6.40-linux-glibc2.12-x86_64 /usr/local/mysql-5.6.40

#做软链接
[root@db04 tools]# ln -s /usr/local/mysql-5.6.40 /usr/local/mysql

#进入其他文件目录
[root@db04 tools]# cd /usr/local/mysql/support-files/

#拷贝配置文件
[root@db04 support-files]# cp my-default.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y

#拷贝启动脚本
[root@db04 support-files]# cp mysql.server /etc/init.d/mysqld

#安装初始化依赖包
[root@db04 support-files]#  yum install -y libaio-devel ncurses-devel cmake 

#下载模块
[root@db04 scripts]# yum install -y autoconf

#进入初始化目录
[root@db04 support-files]# cd ../scripts/

#创建mysql用户
[root@db04 scripts]#  useradd mysql -s /sbin/nologin -M

#初始化
[root@db04 scripts]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
看到2个ok就是初始化完毕

#加入开机自启
[root@db04 mysql-5.6.36]# chkconfig mysqld on

#启动MySQL
[root@db04 scripts]# /etc/init.d/mysqld start

#添加环境变量
[root@db04 scripts]# vim /etc/profile.d/mysql.sh
export PATH="/usr/local/mysql/bin:$PATH"

#加载环境变量
[root@db04 scripts]# source /etc/profile.d/mysql.sh

#检查是否启动成功
[root@db04 scripts]#  ps -ef|grep [m]ysql

#停止运行
[root@db04 scripts]# etc/init.d/mysqld stop

#用systemctl启动
[root@db04 scripts]#  vim /usr/lib/systemd/system/mysqld.service

5.7版本

#下载mysql5.7二进制包，解压到当前目录下

[root@long tools]# tar -zxf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz 


#将解过的mysql5.7包移动到/usr/local/下并改名为mysql

[root@long tools]# mv mysql-5.7.25-linux-glibc2.12-x86_64 /usr/local/mysql


#切换到/usr/local/mysql下

/usr/local/mysql


#新增mysql用户，并禁止shell登陆

[root@long mysql]# useradd -r -g mysql -s /sbin/nologin mysql

#初始化mysql5.7数据库

[root@long mysql]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

复制配置文件并修改

注意，如果./support-files/my-default.cnf 没有这个文件，可以到网上去收一下这个文件的大致内容。

#复制主配置文件
cp ./support-files/my-default.cnf /etc/my.cnf

#修改 /etc/my.cnf 配置文件

# vi /etc/my.cnf
# These are commonly set, remove the # and set as required.
basedir = /usr/local/mysql //指定程序路径
datadir = /usr/local/mysql/data //指定数据存放路径
port = 3306 //指定端口号
# server_id = .....
socket = /tmp/mysql.sock //指定sock文件
复制启动文件并修改相关参数

a.复制启动脚本文件到init.d下

cp ./support-files/mysql.server /etc/init.d/mysqld
b.修改启动脚本相关参数

vim /etc/init.d/mysqld
basedir=/usr/local/mysql //指定程序路径
datadir=/usr/local/mysql/data //指定数据存放路径
​```

#### #启动mysql服务，并查看服务启动状态


[root@long mysql]# /etc/init.d/mysqld start 


[root@long ~]# netstat -ntlp | grep 3306

tcp6       0      0 :::3306                 :::*                    LISTEN      32660/mysqld    

chkconfig --add mysqld //加入开机启动

#重置密码

a.使用初始化临时密码登陆


[root@long mysql]# /usr/local/mysql/bin/mysql -uroot -p'v?_yAzh2.NI>'

mysql: [Warning] Using a password on the command line interface can be insecure.

Welcome to the MySQL monitor.  Commands end with ; or g.


b.修改mysql登陆密码:123


mysql> set password = password('123');
