系统运维技巧（五）MySQL的其他安装方式

第二步，在file中加入/etc/my.cnf和/etc/init.d/mysqld

 
[root@serv02 local]# vim file 
[root@serv02 local]# head -n2 file 
/etc/my.cnf
/etc/init.d/mysqld

第三步，打包

[root@serv02 local]# tar -cPvf mysql.tar -T file
[root@serv02 local]# cd ~
--上述三步可以一步到位

#打包不压缩
[root@serv02 htdocs]# find /usr/local/mysql//etc/my.cnf /etc/init.d/mysqld | xargs tar -cPvf mysql.tar
#打包压缩
[root@serv02 htdocs]# find /usr/local/mysql//etc/my.cnf /etc/init.d/mysqld | xargs tar -cjPvf mysql.tar.bz2

第四步，拷贝到远程机

[root@serv03 ~]# yum install /usr/bin/scp -y
[root@serv02 local]# scp mysql.tar192.168.1.13:/root
root@192.168.1.13's password: 
mysql.tar 100% 1103MB 39.4MB/s 00:28 

第五步，进入远程机，解压

[root@serv03 ~]# tar -xPvf mysql.tar

第六步，添加mysql组和用户，注意组和用户ID应该和源机器的一致

[root@serv01 opt]# groupadd -g 500 mysql
[root@serv01 opt]# useradd -u 500 -g 500 -r -M -s /sbin/nologin mysql 
#如果没有mysql用户，会报如下错误
Starting MySQL. ERROR! Manager of pid-filequit without updating file.

第七步，添加mysql相关命令到环境变量

[root@serv03 ~]# vim ~/.bash_profile
[root@serv03 ~]# cat ~/.bash_profile | grep PATH
PATH=/usr/local/mysql/bin/:$PATH:$HOME/bin
export PATH
[root@serv03 ~]# . ~/.bash_profile 

第八步，启动MySQL

[root@serv03 ~]# /etc/init.d/mysqld start

第九步，登录

[root@serv03 ~]# mysql -uroot -phelloworld
