最开始用服务器的时候，也是对这些环境的安装操作极其陌生，找了很多方式，写这边文章就是为了让更少的童鞋走弯路，下面我们看看具体的操作流程。
1、首先关闭linux的防火墙，执行命令
chkconfig iptables off
2、从mysql官网上下载自己适合的mysql版本/downloads/mysql/5.6.html#downloads，进入mysql官网，依次点击
3、下载后的mysql文件
mysql-5.6.40-linux-glibc2.12-i686.tar.gz
将下载好的mysql压缩文件放置在linux的/usr/local文件夹下，解压该压缩文件
tar -zxvf mysql-5.6.40-linux-glibc2.12-i686.tar.gz
将解压后的文件重命名为mysql
mv mysql-5.6.40-linux-glibc2.12-i686 mysql
4、创建mysql用户组及用户
groupadd mysql
useradd -r -g mysql mysql
5、进入到mysql目录，执行添加MySQL配置的操作
cp support-files/my-f /etc/f 或： cp support-files/my-f /etc/f
是否覆盖？按y 回车
6、编辑/etc/f文件；
vi /etc/f
在f文件中添加或者修改相关配置，更改完成后保存退出

7、在mysql当前目录下设定目录的访问权限（注意后面的小点，表示当前目录）
chown -R mysql .
chgrp -R mysql .
scripts/mysql_install_db --user=mysql
chown -R root .
chown -R mysql data
8、初始化数据（在mysql/bin或者mysql/scripts下有个 mysql_install_db 可执行文件初始化数据库），进入mysql/bin或者mysql/scripts目录下，执行下面命令
./mysql_install_db --verbose --user=root --defaults-file=/etc/f --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql --pid-file=/usr/local/mysql/data/mysql.pid --tmpdir=/tmp
9、启动mysql，进入/usr/local/mysql/bin目录，执行下面命令
./mysqld_safe --defaults-file=/etc/f --socket=/tmp/mysql.sock --user=root &
注意，如果光标停留在屏幕上，表示启动成功，需要我们先关闭shell终端，再开启一个新的shell终端，不要执行退出操作。如果出现 mysql ended这样的语句，表示Mysql没有正常启动，你可以到log中查找问题.
10、设置开机启动，新开启shell中断后，进入mysql目录，执行下面命令
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqldcp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql
chmod 700 /etc/init.d/mysql
chkconfig --add mysqld
chkconfig --level 2345 mysqld on
chown mysql:mysql -R /usr/local/mysql/
重启linux
reboot
查看mysql状态
service mysqld status
11、添加远程访问权限
（1）、添加mysql命令
ln -s /usr/local/mysql/bin/mysql /usr/bin （mysql的安装路径）
（2）、更改访问权限
登录mysql,执行下面命令mysql -uroot -p 密码为空直接回车,运行以下两条命令GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'duan' with grant option;Flush privileges;
退出mysql
exit
重启linux,就完成了
reboot
注：本机访问mysql，root账户默认是没有密码的，端口号默认3306，如果需要修改root账户密码，在/usr/local/mysql/bin目录下，执行下面命令
./mysqladmin -h 127.0.0.1 -P3306 -uroot password 'duan'exit
