MySQL二进制包安装：

  1. 安装包获取方式

    官网下载url: http://dev.mysql.com/downloads/mysql/
    数据库下载url：http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.22-linuxglibc2.5-x86_64.tar.gz
    搜狐下载mirror ： http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.22-linux-glibc2.5x86_64.tar.gz

  2. 数据库规划
    安装场景
    操作系统 Red Hat Enterprise Linux Server release 6.8 (Santiago)

    数据库版本  mysql-5.6.22-linux-glibc2.5-x86_64
    IP地址 192.168.1.100/24 
    数据库安装目录 /usr/local/mysql
    数据库数据文件目录 /data/mysql/mysql_3306

  3. 安装步骤

  • 关闭相关服务

[root@localhost ~]# getenforce
Enforcing
[root@localhost ~]# setenforce 0                    >临时关闭，永久关闭可修改配置文件
[root@localhost ~]# getenforce
Permissive
[root@localhost ~]# cat /etc/selinux/config | grep -v ^# | grep -v ^$
SELINUX=disabled
SELINUXTYPE=targeted 
 [root@localhost ~]# /etc/init.d/iptables stop
[root@localhost ~]# chkconfig iptables off

  • 目录结构：

# mkdir -p /opt/{software,mysql}
# tree /opt/
├── mysql
└── software

  • 上传MySQL安装包

  • 解压MySQL安装包

[root@db1 software]# ls
mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@db1 software]# tar -zxf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@db1 software]# ls
mysql-5.6.39-linux-glibc2.12-x86_64 mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@localhost software]# mv mysql-5.6.22-linux-glibc2.5-x86_64 /opt/mysql/mysql5.6
[root@localhost software]# cd ..
[root@localhost opt]# cd mysql/
[root@localhost mysql]# ls
mysql5.6

  • 安装MySQL

[root@db1 software]# cd /usr/local/
[root@db1 local]# ln -s /opt/mysql/mysql5.6 mysql
[root@localhost local]# ls -l mysql
lrwxrwxrwx. 1 root root 19 Jan 13 19:51 mysql -> /opt/mysql/mysql5.6

  • 创建MySQL用户

[root@db1 data]# mkdir -p /data/mysql/mysql_3306/{data,tmp}
[root@db1 data]# tree /data
/data
└── mysql
    └── mytest_3306
[root@db1 home]# groupadd mysql                             > 创建mysql组
[root@db1 home]# useradd mysql -g mysql -d /data/mysql/mytest_3306 -s /dev/null                         >新建的 mysql 用户，属组mysql ，homedir 是 /data/mysql/mytest_3306,登录shell为空

  • 初始化MySQL数据库datadir

[root@db1 home]# chown -R mysql.mysql /data/mysql/mysql_3306                >修改属主属组
[root@db1 home]# cd /usr/local/mysql/
[root@db1 mysql]# chown -R mysql.mysql /usr/local/mysql/*
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql/mysql_3306/data
Installing MySQL system tables...OK

Filling help tables...OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  /usr/local/mysql/bin/mysqladmin -u root password 'new-password'
  /usr/local/mysql/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:

  /usr/local/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

  cd . ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

The latest information about MySQL is available on the web at

  http://www.mysql.com

Support MySQL by buying support/licenses at http://shop.mysql.com

New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

  • 添加环境变量

[root@localhost mysql]# echo "PATH=$PATH:/usr/local/mysql/bin">>/etc/profile
[root@localhost mysql]# source /etc/profile

  • 启动服务配置

[root@localhost mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# /etc/init.d/mysqld start
Starting MySQL.......... SUCCESS!
