pg数据库

默认使用pg_dump,命令行会提示输入密码,编写这个文件:/root/.pgpass,内容如下:

hostname:port:database:username:password

权限修改为0600

再编写备份脚本:

#!/bin/sh

time=`date "+%Y%m%d%H%M%S"`

war_home=/opt/apache-tomcat-7.0.65/webapps


#stop tomcat

echo 停止tomcat

service tomcat stop


# 备份数据库

pg_dump -h localhost --file pgdata/${time}.sql -U admin database_prod


如果是tar备份多个目录,写法:

tar -czf /root/wx_res.tar.gz mb mch news uploads
