准备
运行环境
[root@dbmysql ~]# lsb_release -a
LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: CentOS
Description: CentOS release 6.7 (Final)
Release: 6.7
Codename: Final
下载安装包
下载地址 http://dev.mysql.com/downloads/mysql/#downloads
安装包根据自己环境选择
mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
检查是否安装
[root@dbmysql ~]# rpm -qa|grep -i mysql
mysql-libs-5.1.61-4.el6.x86_64
可见已经安装了库文件，应该先卸载，不然会出现覆盖错误。注意卸:载时使用了--nodeps选项，忽略了依赖关系
[root@dbmysql ~]# rpm -e mysql-libs-5.1.61-4.el6.x86_64 --nodeps
添加mysql组和mysql用户
用于设置mysql安装目录文件所有者和所属组
[root@dbmysql ~]# groupadd mysql
[root@dbmysql ~]# useradd -r -g mysql mysql
useradd -r参数表示mysql用户是系统用户，不可用于登录系统
解压文件
将二进制文件解压到指定的安装目录，这里指定为/usr/local
将下载的安装文件上传到/usr/local
[root@dbmysql ~]# cd/usr/local/
[root@dbmysql ~]# tar -zxvf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
[root@dbmysql ~]# rm -rf mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz
[root@dbmysql ~]# ln -s mysql-5.5.29-linux2.6-x86_64 mysql
修改所属的组和用户
[root@dbmysql ~]# cd mysql
[root@dbmysql ~]# chown -R mysql:mysql ./
安装
[root@dbmysql ~]# ./scripts/mysql_install_db --user=mysql
修改当前目录拥有者为root用户
[root@dbmysql ~]# chown -R root:root ./
修改当前data目录拥有者为mysql用户
[root@dbmysql ~]# chown -R mysql:mysql data
到此数据库安装完毕
将mysql服务加入开机自启动项
首先需要将scripts/mysql.server服务脚本复制到/etc/init.d/，并重命名为mysql
[root@dbmysql ~]# cp ./support-files/mysql.server /etc/init.d/mysql
通过chkconfig命令将mysqld服务加入到自启动服务项中
[root@dbmysql ~]# chkconfig --add mysql
chkconfig --list mysql
mysql 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
重启系统，mysqld就会自动启动了
检查mysql是否启动成功
[root@dbmysql ~]# netstat -anp|grep mysql
tcp 0 0 :::3306 :::* LISTEN 2072/mysqld
unix 2 [ ACC ] STREAM LISTENING 15269 2072/mysqld /tmp/mysql.sock
[root@dbmysql ~]# ps -ef|grep mysql

root 2280 2249 0 22:45 pts/0 00:00:00 grep mysql
修改 root 密码

防火墙
关闭防火墙对 3306 端口的拦截
$ iptables -L -n | grep 3306
$ firewall-cmd --add-port=3306/tcp --permanent
$ firewall-cmd --reload
以上是centos7方式，如果遇到centos6，请用下面的命令：
$ iptables -I INPUT -p tcp -m tcp --dport 3306 -j ACCEPT
$ service iptables save 或者 /etc/rc.d/init.d/iptables save
重启
service iptables restart
查看
/etc/init.d/iptables status
