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:

img

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 .

img

#chown -R mysql /data/mysql

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

img

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

img

8修改系统配置文件

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

img

# 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;

img

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:

img

# 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]
