Linux环境下MySQL5.6二进制安装

本次安装的MySQL版本信息如下：mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz，如需要安装包，请留言。

MySQL部署方式：1.yum部署；2.二进制部署

1、上传文件包

2、检查是否安装Mysql

ps -ef | grep mysqld
rpm -qa | grep -i mysql

没有Mysql进程，表示未安装，安装包有个，但不用

3、解压并重命名

解压：tar -xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
重命名：mv mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz mysql

4、创建用户组和用户（生产环境中，使用的不可能是root，故只能分配组权限）

创建dba用户组：groupadd -g 101 dba
创建用户mysqladmin(主组dba；用户组为root，dba；家目录为/usr/local/mysql)：useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

PS：红框内容表示，我们未将用户环境变量文件复制到设定的家目录中，需手动复制

5、修改mysqladmin用户密码并复制环境变量配置文件到mysql用户的家目录

修改密码：passwd mysqladmin
复制变量：cp /etc/skel/.* /usr/local/mysql

6、创建配置文件（权限640）

vi /etc/my.cnf
删除内容后，复制以下内容到文件
[client]
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock
 
[mysqld]
port            = 3306

7、修改用户组和权限

chown mysqladmin:dba /etc/my.cnf
chmod 640 /etc/my.cnf

chown -R mysqladmin:dba /usr/local/mysql
chmod -R 755 /usr/local/mysql

mkdir arch
用于装归档文件

8、第一次安装

/usr/local/mysql/scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

没有报错，说明安装成功

删除家目录中的my.cnf，以免造成勿扰

9、配置Mysql服务启动，查看进程并启动

cd /usr/local/mysql
#将服务文件拷贝到ini.d，并重命名
cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
chmod +x /etc/rc.d/init.d/mysql
#若之前安装服务，需先删除服务，本次省略
#添加服务
chkconfig --add mysql
#设置启动级别345
chkconfig --level 345 mysql on

[root@hadoop000 mysql]# vi /etc/rc.local 

修改内容

#!/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

10、修改密码（登录MySQL以后，需要对数据库添加密码）

use mysql;
update user set Password=password('123456') where user='root';
delete from user where user='';

11、刷新权限（MySQL更新用户以后要刷新权限）

flush privileges;

12、配置环境变量

vi /urs/local/mysql/.bash_profile
