linux安装mysql数据库教程

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/ 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

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

linux安装mysql数据库教程

# 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;

如提示不能成功连接,可能需要添加需要监听的端口

/sbin/iptables -I INPUT -p tcp –dport 3306 -j ACCEPT

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
# 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
