部分代码解析:

#!/usr/bin/python

'''The rsync_server
config'''
注意区别三个'''与一个'的区别:一个',表示单行的注释,三个''',表示多行的注释,不用使用换行符

import os,stat,sys,time
导入模块

now=time.strftime('%Y%m%d%H%M')
cfgrsyncd='''
#rsyncd#
uid = root
gid = root
use chroot = no
max connections = 5
lock file = /var/log/rsync/rsyncd.lock
log file = /var/log/rsync/rsyncd.log
pid file = /var/log/rsync/rsyncd.pid
hosts allow = 192.168.1.9
hosts deny = *
ignore errors
read only = yes
list = no
auth users = username
secrets file = /etc/.passwd\n
'''

cfgxrsync='''
service rsync

    disable = no
    socket_type     = stream
    wait            = no
    user            = root
    server          = /usr/bin/rsync
    server_args     = --daemon --config=/etc/rsyncd.conf
    log_on_failure  += USERID
}'''
定义时间等变量

print 'First,Please Install Xinetd And Rsync Server \n'
在执行脚本的时候显示

#A function definition of xinetd-rsync
def cfgxrs():
    if os.path.exists('/etc/xinetd.d/rsync'):
        cmd_mv='mv /etc/xinetd.d/rsync /etc/xinetd.d/rsync.%s' % (now)
        os.system(cmd_mv)
    content=file('/etc/xinetd.d/rsync','w')
    content.write(cfgxrsync)
    content.close()
函数功能:
1·创建xinetd启动的rsync文件
2·首先检查文件是否存在,如果存在则执行mv命令
3·否则,就以写入的模式,添加"cfgxrsync"定义的内容

#A function definition of password-file
def cfgpwd():
    cfgpasswd='''backup:passwd'''
    content=file('/etc/.rsyncd.passwd','w')
    content.write(cfgpasswd)
    content.close()   
    os.chmod('/etc/.rsyncd.passwd', stat.S_IREAD)
函数功能:
1·创建密码文件
2·修改密码文件权限,stat.S_IREAD代表600

#A function definition of rsyncd
def cfgsrv():
    if os.path.exists('/etc/rsyncd.conf'):
        cmd_mv='mv /etc/rsyncd.conf /etc/rsyncd.conf.%s' % (now)
        os.system(cmd_mv)
    if os.path.exists('/var/log/rsync'):
        print '/var/log/rsync is already established.'
    else:
        os.mkdir('/var/log/rsync')
    content=file('/etc/rsyncd.conf','w')
    content.write(cfgrsyncd)
    content.close()
函数功能:
1·创建rsyncd.conf配置文件
2·创建日志目录

#A function definition of '/etc/rsyncd.conf' is module append
def cfgapd():
    try:
        try:
            content=file('/etc/rsyncd.conf','a')
            mod=raw_input('please enter the module: \n>')+'\n'
            content.write(mod)
            pth='path='+raw_input('please enter the path:> \n>')+'\n'
            content.write(pth)
            content.close()
        except:
            print 'Please enter a correct Module and Path \n'
            sys.exit()
            print 'Scripting termination !! \n'
    finally:
        content.close()
函数功能:
1·手动输入模块名
2·增加交互性。不便于使用,所以下面没有调用
3·try...finally,不管try段如何,都运行finally段的代码

#Display file content
def cfgdpy():
    print '\nPrint ''/etc/rsyncd.conf'' content \n'
    time.sleep(1)
    content=file('/etc/rsyncd.conf','r')
    while True:
        line = content.readline()
        if len(line) == 0:
            break
        print line,
    content.close()
函数功能:
1·显示配置文件内容
2·while True循环,把每一行都赋给line,if len(line) == 0:表示到了最后一行

def srvrst():
    print '\nexec /etc/init.d/xinetd restart'
    cmd='/etc/init.d/xinetd restart'
    time.sleep(2)
    os.system(cmd)
重启
