linux(CentOS6.7) 环境Mysql 5.7.17安装教程分享给大家，供大家参考，具体内容如下：

1系统约定  
安装文件下载目录：/data/software  
Mysql目录安装位置：/usr/local/mysql  
数据库保存位置：/data/mysql  
日志保存位置：/data/log/mysql

2下载mysql  
在官网：[http://dev.mysql.com/downloads/mysql/][http_dev.mysql.com_downloads_mysql] 中，选择以下版本的mysql下载：

![1106390-20170320162305111-1077112774.png][]

执行如下命名：  
\#mkdir /data/software  
\#cd /data/software

\--下载安装包

\--建议：在windows上使用迅雷下载，速度很快（我的是1M/s），然后用工具（Xftp）上传到 /data/software目录下；  
\#wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86\_64.tar.gz

3解压压缩包到目标位置

\#cd /data/software

\--解压压缩包

\#tar -xzvf /data/software/mysql-5.7.17-linux-glibc2.5-x86\_64.tar.gz

\--移动并修改文件名

\#mv /data/software/mysql-5.7.17-linux-glibc2.5-x86\_64 /usr/local/mysql

4创建数据仓库目录

\--/data/mysql 数据仓库目录  
\# mkdir /data/mysql           
\#ls /data/

![1106390-20170320163520815-392452153.png][]

5新建mysql用户、组及目录  
\#      ---新建一个msyql组  
\# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql     ---新建msyql用户禁止登录shell

6改变目录属有者

\#cd /usr/local/mysql  
\#pwd  
\#chown -R mysql .  
\#chgrp -R mysql .

![1106390-20170320163742861-882299968.png][]

\#chown -R mysql /data/mysql

7配置参数  
\# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

![1106390-20170320163910736-784985642.png][]

此处需要注意记录生成的临时密码，如上文结尾处的：YLi>7ecpe;YP  
\#bin/mysql\_ssl\_rsa\_setup  --datadir=/data/mysql

![1106390-20170320164009611-651835333.png][]

8修改系统配置文件

\#cd /usr/local/mysql/support-files

![1106390-20170320164033705-2053069616.png][]

\# cp my-default.cnf /etc/my.cnf  
\# cp mysql.server /etc/init.d/mysql

\# vim /etc/init.d/mysql

修改以下内容：

![1106390-20170320164202736-226288281.png][]

9启动mysql

\# /etc/init.d/mysql start

\--登陆

\# mysql -hlocalhost -uroot -p

--如果出现：-bash: mysql: command not found

--就执行： \# ln -s /usr/local/mysql/bin/mysql /usr/bin --没有出现就不用执行

\--输入第6步生成的临时密码

\--修改密码

mysql> set password=password('root');

\--设置root账户的host地址（修改了才可以远程连接）

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

\--查看表

mysql> use mysql;  
mysql> select host,user from user;

\--这里就可以使用远程连接测试了；

![1106390-20170320164832877-1545398381.png][]

10添加系统路径  
\# vim /etc/profile  
添加：  
export PATH=/usr/local/mysql/bin:$PATH  
如下：

![1106390-20170320170252549-1031155225.png][]

\# source /etc/profile

11配置mysql自动启动  
\# chmod 755 /etc/init.d/mysql  
\# chkconfig --add mysql  
\# chkconfig --level 345 mysql on

以上就是linux环境Mysql 5.7.13安装教程，希望对大家的学习有所帮助。

补充：

\--退出mysql命令窗口

\#exit

--查看mysql状态

\#service mysql status

\--停止mysql

\#service mysql stop

\--启动mysql

\#service mysql start

附my.cnf（这是一个配置mysql配置文件，暂时可以不用管，如你想钻研 你可以百度或google “mysql my.cnf 配置详情”）

/etc/my.cnf  
\# For advice on how to change settings please see  
\# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html  
\# \*\*\* DO NOT EDIT THIS FILE. It's a template which will be copied to the  
\# \*\*\* default location during install, and will be replaced if you  
\# \*\*\* upgrade to a newer version of MySQL.  
  
\[mysqld\]  
  
\# 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 = 10G  
  
\# Remove leading \# to turn on a very important data integrity option: logging  
\# changes to the binary log between backups.  
log\_bin  
character-set-server=utf8  
collation-server=utf8\_bin  
init-connect='SET NAMES utf8'  
\# These are commonly set, remove the \# and set as required.  
basedir = /usr/local/mysql  
datadir = /export/mysql/var  
port = 3306  
server\_id = 22206  
socket = /export/mysql/mysql.sock  
binlog\_format = statement  
\# 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  
log\_bin\_trust\_function\_creators = on  
sql\_mode=NO\_ENGINE\_SUBSTITUTION,STRICT\_TRANS\_TABLES  
  
lower\_case\_table\_names=1
