MySQL如何部署

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-f(640)

[root@sht-sgmhadoopnn-01 ~]# vi /etc/my-f     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-f  修改my-f的用户及用户组

[root@ruozehadoop000  local]# chmod  640 /etc/my-f   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-f       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
