二进制安装MySQL

一.下载MySQL

官网下载MySQL 地址：http://www.mysql.com/downloads/ 



点击社区版本MySQL





选择MySQL版本



选择操作系统



点击Download下载MySQL



PS:也可以通过wget下载

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.27-linux-glibc2.5-x86_64.tar.gz
http://mirrors.sohu.com/
wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.27-linux-glibc2.5-x86_64.tar.gz
二.安装MySQL
环境

# cat /etc/redhat-release 

CentOS release 6.5 (Final)

# mysql -V

mysql  Ver 14.14 Distrib 5.6.29, for linux-glibc2.5 (x86_64) using  EditLine wrapper

1.解压二进制安装包创建硬链接 

# mkdir -pv /opt/mysql

#tar -xvf mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz

cd /usr/local/

# ln -s /opt/mysql/mysql-5.6.29-linux-glibc2.5-x86_64  mysql

2.新建mysql用户，用户组，指定homedir

#groupadd mysql
#mkdir -pv /data/mysql/mysql_3376/{data,logs,tmp}

#useradd  mysql -g mysql -d /data/mysql/mysql_3376/ -s /dev/null

# chown -R mysql:mysql  /data/mysql/mysql_3376/

# chown -R mysql:mysql /usr/local/mysql/

# chown -R mysql:mysql /opt/mysql/

3.新建配置文件/etc/my.cnf 

[client]

port            = 3376

# The MySQL server

[mysqld]

PS：如果在现有配置文件修改可以选择

MySQL配置文件结构

client：对mysql的所有客户端都生效

mysql：只对mysql这个命令有效

mysqld_multi：多实例启动

mysqld：是必须的配置选项 

4.初始化datadir
# ./scripts/mysql_install_db

PS:因为在/etc/my.cnf 指定了user和datadir所以直接执行初始化脚本即可

 

5.添加环境变量

#echo 'export MySQL_HOME=/usr/local/mysql' >> /etc/profile
#echo 'export PATH=$PATH:$MySQL_HOME/bin' >> /etc/profile

# source /etc/profile

# echo $PATH

/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/mysql/bin

6.启动

#pwd
/usr/local/mysql/support-files

# cp mysql.server  /etc/init.d/mysql

# /etc/init.d/mysql start

Starting MySQL.. SUCCESS! 

7.安全加固

> delete from mysql.user where user!='root' or host!='localhost';

> truncate table mysql.db;

> drop database test;

> flush privileges;

8.检查启动是否正常

# ps -ef |grep mysql

查看error.log是否有报错
