Linux+Redis实战教程_day02_Linux系统上安装MySQL

Linux系统上安装MySQL

安装MySQL

卸载自带mysql

查询mysql的安装情况，可以直接使用了

rpm -qa | grep -i mysql –-color

卸载原生的MySQL

rpm -e --nodeps mysql-libs-5.1.71-1.el6.i686

上传mysql到Linux

CRT远程连接软件中：alt+p 拖拽上传即可

安装依赖（准备阶段已经安装过了）

yum -y install libaio.so.1 libgcc_s.so.1 libstdc++.so.6

yum  update libstdc++-4.4.7-4.el6.x86_64

安装mysql的服务端

安装服务端

rpm -ivh MySQL-server-5.5.49-1.linux2.6.i386.rpm

默认安装在usr目录中

[root@yejing ~]# rpm -ivh MySQL-server-5.1.73-1.glibc23.i386.rpm

Preparing...                ########################################### [100%]

   1:MySQL-server           ########################################### [100%]

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'

/usr/bin/mysqladmin -u root -h yejing password 'new-password'

Alternatively you can run:

/usr/bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default.  This is

strongly recommended for production servers.

See the manual for more instructions.

Please report any problems with the /usr/bin/mysqlbug script!

Starting MySQL....[确定]

[root@yejing ~]#

安装mysql的客户端

rpm -ivh MySQL-client-5.5.49-1.linux2.6.i386.rpm

[root@yejing ~]# rpm -ivh MySQL-client-5.1.73-1.glibc23.i386.rpm

Preparing...                ########################################### [100%]

   1:MySQL-client           ########################################### [100%]

[root@yejing ~]#

启动mysql的服务

启动MySQL服务

service mysql start

设置mysql初始密码并登陆MySQL

/usr/bin/mysqladmin -u root password '123456'

设置开机自动启动mysql

加入到系统服务：

chkconfig --add mysql

自动启动（关闭）：

chkconfig mysql on/off

开启远程服务

登录mysql:

//赋予root用户所有权限，远程登录密码是123456

grant all privileges on *.* to 'root' @'%' identified by '123456';

flush privileges;//刷新权限

设置Linux的防火墙

Linux防火墙默认拦截3306端口

/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT//将3306端口进行防火墙的开启

/etc/rc.d/init.d/iptables save//防火墙重新刷新保存

[root@yejing ~]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

[root@yejing ~]# /etc/rc.d/init.d/iptables save

iptables：将防火墙规则保存到 /etc/sysconfig/iptables：[确定]
