我的博客搭建在一个KVM VPS上，今天也写了一个fabfile来dump数据库、打包WordPress目录，并下载到本地。fabfile代码如下：
代码如下 #!/usr/bin/python# use Fabric to manage all the hosts in perf env.
# usage: fab -f vps_fabfile.py download_backup
# author: Jay
from fabric.context_managers import cd
#from fabric.context_managers import settings
from fabric.operations import *
from fabric.api import *
from datetime import datetime
env.hosts = "smilejay.com"
env.port = 22
env.user = "root"
env.password = "1234"
@task
def download_backup():
# backup my WP file and database, download them to the local machine
dt = datetime.now().strftime("%Y-%m-%d-%H-%M-%S")
local_dir = "/home/jay/backup"
with cd("/tmp"):
nginx = "/usr/share/nginx"
wp_root = "/usr/share/nginx/html"
exclude = "html/wp-content/cache"
bk_name = "wp_%s.tar.gz" % dt
clean = "rm -f wp*.tar.gz"
mysql = "mysqldump -uroot -p1234 -A > %s/mysql-dump.sql" % wp_root
tar = "tar -zcf %s -C %s html --exclude=%s" % (bk_name, nginx, exclude)
run(clean)
run(mysql)
run(tar)
get(bk_name, "%s/%s" % (local_dir, bk_name))

当然，我一般也会使用BackWPup插件来备份WordPress；刚好发现，前段时间使用Nginx替代Apache后，BackWPup运行时仍然要写“/var/www/html/wp-content/backwpup-logs/”目录，所以有个权限问题，最近两个月都是运行失败了。后来对这个目录开放了写权限就没问题了。
