install mysql

1.查看操作系统相关信息。

 

[root@linuxidc ~]# cat /etc/issue 

CentOS release 6.5 (Final) 

Kernel \r on an \m 

[root@linuxidc ~]# uname -a 

Linux linuxidc 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

 

2.创建需要下载rpm软件包的目录。

1 [root@linuxidc ~]# mkdir -p /taokey/tools

 

3.查看下是否有系统自带mysql的rpm包，如果有，需要删除自带的旧rpm包。

[root@linuxidc ~]# rpm -qa | grep mysql 

mysql-libs-5.1.71-1.el6.x86_64 

[root@linuxidc ~]# yum -y remove mysql-libs-5.1* 

[root@linuxidc ~]# rpm -qa | grep mysql 

[root@linuxidc ~]#

 

4.在MySQL官网下载安装MySQL-5.6.21所需的rpm软件包。

需要下载三个rpm软件包：

MySQL-client-5.6.21-1.rhel5.x86_64.rpm  

MySQL-devel-5.6.21-1.rhel5.x86_64.rpm  

MySQL-server-5.6.21-1.rhel5.x86_64.rpm 

[root@linuxidc ~]# cd /taokey/tools/ 

[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm 

[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm 

[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm

 

5.下载完之后，安装三个rpm软件包。

[root@linuxidc tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm 

error: Failed dependencies:

        libaio.so.1()(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64

        libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64

        libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64

安装MySQL-server报错，原因是没有安装libaio，系统缺少libaio.so此软件包，下边yum安装一下libaio.so软件包。

[root@linuxidc tools]# yum install -y libaio 

[root@linuxidc tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm 

[root@linuxidc tools]# rpm -ivh MySQL-client-5.6.21-1.rhel5.x86_64.rpm

6.修改配置文件位置。

[root@linuxidc tools]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

 

7.初始化MySQL及修改MySQL默认的root密码。

[root@linuxidc tools]# /usr/bin/mysql_install_db 

[root@linuxidc tools]# ps -ef | grep mysql 

root      2188    1  0 14:48 pts/1    00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/linuxidc.pid 

mysql    2303  2188 30 14:48 pts/1    00:00:02 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/linuxidc.err --pid-file=/var/lib/mysql/linuxidc.pid 

root      2331  1853  0 14:49 pts/1    00:00:00 grep mysql 

[root@linuxidc tools]# netstat -anpt | grep 3306

[root@linuxidc tools]# more /root/.mysql_secret

8.设置MySQL服务开机自启动。

[root@linuxidc tools]# chkconfig mysql on 

[root@linuxidc tools]# chkconfig mysql --list 

mysql          0:off  1:off  2:on    3:on    4:on    5:on    6:off
