Linux(CentOS6.7) 安装MySql5.7数据库 图文教程

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：

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][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/

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 .

\#chown -R mysql /data/mysql

7配置参数

# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql #

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

8修改系统配置文件

\#cd /usr/local/mysql/support-files

# 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：

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；

10添加系统路径

# vim /etc/profile #

添加：  
export PATH=/usr/local/mysql/bin:$PATH  
如下：

# 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
