第二步,停掉MySQL
[root@serv01 ~]# /etc/init.d/mysqld stop Shutting down MySQL... SUCCESS!
第三步,创建备份目录,并修改拥有者和所属组
[root@serv01 ~]# mkdir /databackup [root@serv01 ~]# chown mysql.mysql /databackup/ -R [root@serv01 ~]# ll /databackup/ -d drwxr-xr-x. 2 mysql mysql 4096 Sep 10 17:46 /databackup/ [root@serv01 ~]# cd /databackup/
第四步,冷备(使用tar命令)
[root@serv01 databackup]# tar -cvPzf mysql01.tar.gz
第五步,测试冷备的数据是否正常,我们删除掉data下的所有数据
[root@serv01 databackup]# rm -rf /usr/local/mysql/data/*
第六步,删除所有数据后数据库不能启动
[root@serv01 databackup]# /etc/init.d/mysqld start Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/data/serv01.host.com.pid).
第七步,恢复数据(使用tar命令)
[root@serv01 databackup]# tar -xvPf mysql01.tar.gz
第八步,启动MySQL,然后登录MySQL,查看数据是否丢失,如果数据正常代表冷备成功
[root@serv01 databackup]# /etc/init.d/mysqld start Starting MySQL.. SUCCESS! [root@serv01 ~]# mysql Welcome to the MySQL monitor. Commands end with ; or \g.
