环境：centOS

1、下载mysql安装文件

[root@localhost ~]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

2、安装下载的rpm文件

[root@localhost ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

3、安装mysql服务

[root@localhost yum.repos.d]# yum install mysql-server

• 安装依赖文件可能需要花费很长时间，耐心等待，同时一路输入【Y】就好

3、修改mysql配置文件

[root@localhost yum.repos.d]# vim /etc/my.cnf

• 配置文件和windows环境无区别

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

[mysqld]

#

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

#

# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

# log_bin

#

# Remove leading # to set options mainly useful for reporting servers.

# The server defaults are faster for transactions and fast SELECTs.

# Adjust sizes as needed, experiment to find the optimal values.

# join_buffer_size = 128M

# sort_buffer_size = 2M

# read_rnd_buffer_size = 2M

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

# Recommended in standard MySQL setup

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

• 修改完成后别忘记重启mysql服务

[root@localhost yum.repos.d]# service mysql restart

4、设置mysql远程访问

• 修改root密码

mysql> use mysql

mysql> update user set password=password('root') where user='root';

mysql> exit

• 修改完成后重启服务

[root@localhost yum.repos.d]# service mysql restart

• 通过用户名密码登录

[root@localhost yum.repos.d]# mysql -u root -p

• 修改主机限制，让mysql可以远程访问

mysql> grant all privileges on *.* to 'root'@'%' identified by 'password';

mysql> flush privileges;

mysql> exit;

• 重启mysql服务

[root@localhost yum.repos.d]# service mysql restart

• 开启端口
• • 经常用linux小伙伴肯定知道，linux很多端口默认是关闭，我们需要根据自己的需要进行开启，这里没有修改端口，按默认3306开启的，这个命令是通用的，要开启某个端口只需要将端口号改成对应的即可

[root@localhost yum.repos.d]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

• 然后就可远程连接我们linux环境下的mysql了
