小编给大家分享一下MySQL如何部署，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

1.Download
[root@ruozehadoop000 ~]# cd /usr/local
#选择win7的mysql软件包
[root@ruozehadoop000 local]# rz 导入软件包

2.Check isnot install
[root@ruozehadoop000 local]# ps -ef|grep mysqld
root 2493 2423 0 19:48 pts/3 00:00:00 grep mysqld
[root@ruozehadoop000 local]# rpm -qa |grep -i mysql

3.tar and mv
[root@ruozehadoop000 local]# tar -xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz 解压
[root@ruozehadoop000 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 MySQL 改名

4.Create group and user
[root@ruozehadoop000 local]# groupadd -g 101 dba 创建dba group
[root@ruozehadoop000 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin 创建mysqladmin用户，添加uid，gid以及组和家目录。

为什么要创建mysqladmin/dba？
1）一个用户只对一个组件

important：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@ruozehadoop000 local]# cp /etc/skel/.* /usr/local/mysql 复制环境变量到家目录

5.Create /etc/my.cnf(640)
[root@sht-sgmhadoopnn-01 ~]# vi /etc/my.cnf 配置cnf文件
[client]
port = 3306
socket = /usr/local/mysql/data/mysql.sock
[mysqld]

6.chown and chmod privileges and try first install
[root@ruozehadoop000 local]# chown mysqladmin:dba /etc/my.cnf 修改my.cnf的用户及用户组
[root@ruozehadoop000 local]# chmod 640 /etc/my.cnf 修改其权限

[root@ruozehadoop000 local]# chown -R mysqladmin:dba /usr/local/MySQL 修改MySQL文件夹的用户及用户组
[root@ruozehadoop000 local]# chmod -R 755 /usr/local/mysql 修改其权限
[root@ruozehadoop000 local]# su - mysqladmin 进入mysqladmin用户
[mysqladmin@ruozehadoop000 ~]$ mkdir arch 创建arch文件夹

安装
[mysqladmin@ruozehadoop000 ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

7.Configure mysql service and boot auto start
[root@ruozehadoop000 ~]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@ruozehadoop000 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
[root@ruozehadoop000 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@ruozehadoop000 mysql]# chkconfig --del mysql
#添加服务
[root@ruozehadoop000 mysql]# chkconfig --add mysql
[root@ruozehadoop000 mysql]# chkconfig --level 345 mysql on

8.Start mysql and to view process and listening

[root@ruozehadoop000 mysql]# su - mysqladmin
[mysqladmin@ruozehadoop000 ~]$ pwd
/usr/local/mysql
[mysqladmin@ruozehadoop000 ~]$ rm -rf my.cnf 删除同名文件避免混淆
[mysqladmin@ruozehadoop000 ~]$ bin/mysqld_safe &
不要忘记，按回车键

[mysqladmin@ruozehadoop000 ~]$ ps -ef|grep mysqld 查看mysqld的进程

[mysqladmin@ruozehadoop000 ~]$ netstat -tulnp | grep MySQL 查看端口号

[root@ruozehadoop000 local]# service mysql status 查看mysql的状态

9.Login mysql
[mysqladmin@ruozehadoop000 ~]$ mysql 直接回车1次空账号空密码
[mysqladmin@ruozehadoop000 ~]$ mysql -uroot -p 直接回车2次 root 空密码

mysql> show databases;查看数据库

10.Update password and Purge user
mysql> use mysql
Database changed

mysql> select user,host,password from user;查看用户

mysql> update user set password=password('123456') where user='root'; 修改用户密码

mysql> delete from user where user=''; 删除指定用户
mysql> flush privileges;刷新权限

11.Configure .bash_profile
[mysqladmin@sht-sgmhadoopnn-01 ~]$ cat .bash_profile 修改环境变量

export MYSQL_BASE=/usr/local/mysql
export PATH=${MYSQL_BASE}/bin:$PATH

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