saltstack的深入-管理python-pip
操作内容：
一、基础环境
1、使用tvm-saltmaster操作
2、网络：
eth0：host-only（用于虚拟内网，手动固定IP，这样从宿主机可以直接连接到这个vm）
eth1：NAT（用于上外网，动态IP）
[root@tvm-zabbix ~]# cd /etc/sysconfig/network-scripts/
[root@tvm-zabbix network-scripts]# cat ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.56.253
PREFIX=24
GATEWAY=192.168.56.1
DNS1=192.168.56.254
[root@tvm-zabbix network-scripts]# cat ifcfg-eth1
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
DNS1=192.168.56.254
二、配置
1、文件结构
[root@tvm-saltmaster base]# tree ops/
ops/
└── bin.sls
0 directories, 1 file
[root@tvm-saltmaster base]# tree conf.d/ops/
conf.d/ops/
└── bin
├── pw
├── randchars.py
└── sendEmail
1 directory, 3 files
2、sls配置
[root@tvm-saltmaster base]# cat ops/bin.sls
## 此处列出需要的软件包
#
python-pip:
pkg.installed:
- name: python-pip
- require_in:
-file: pip-pkgs
pip-pkgs:
pip.installed:
- names:
- virtualenvwrapper
- pwgen
/usr/bin/sendEmail:
file.managed:
- source: salt://conf.d/ops/bin/sendEmail
- mode: 755
/usr/bin/pw:
file.managed:
- source: salt://conf.d/ops/bin/pw
- mode: 755
/usr/bin/randchars:
file.managed:
- source: salt://conf.d/ops/bin/randchars.py
- mode: 755
三、执行
[root@tvm-saltmaster base]# salt 'tvm-*' state.sls ops.bin test=True
[root@tvm-saltmaster base]# salt 'tvm-*' state.sls ops.bin
增加到top.sls中
[root@tvm-saltmaster base]# cat top.sls
base:
'tvm-yum':
- dnsmasq
- crontab
- web
'tvm-zabbix':
- mysql.server
- zabbix.server
- zabbix.web
'*':
- abc
- monit
- postfix
- salt.minion
- ssh
- vim
- zabbix.agent
- ops.bin
四、总结
此处使用到：
pip.installed
使用时，需确保安装了python-pip这个包，否则会提示异常。
且pip安装包时，对应的主机可以连接到外网，如果没联网，有如下报错：
----------

五、附上几个小工具的用法
1、乱序输出字符 pw
其他人写的一个小脚本，调用的是pip安装的pwgen这个工具
[root@tvm-test ~]# cat /usr/bin/pw
#!/usr/bin/python
#
# 2015/8/14
import os
import sys
def gen_pw():
# yum -y install python-pip
# pip install pwgen
p = os.popen('/usr/bin/pwgen -1 -B -n 10')
p = p.read().strip('\n')
p = p[:5].upper() + p[5:].lower()
return p
def print_msg():
p1 = gen_pw()
p2 = gen_pw()
#msg = 'root:{0} root1:{1}'.format(p1,p2)
msg = '{0} {1}'.format(p1,p2)
print msg
if __name__ == '__main__':
print_msg()
2、乱序输出字符 randchar
自己写的一个小脚本，生成一些简单的字符
[root@tvm-test ~]# cat /usr/bin/randchars
#!/bin/env python
#
# 2015/08/10
import random
class RandChars(object):
'''
RandChars(24).generate()
'''
# char pools
pools = '23456789'
pools += 'abcdefghijkmnpqrstuvwxyz'
pools += 'ABCDEFGHIJKMNPQRSTUVWXYZ'
pools += '~!@#$%^&*()_+'
# pool size
pool_size = len(pools)
def __init__(self, length=12):
self.length = length
# get a char from pool
def fetch_one(self):
rnd_index = random.randint(0, self.pool_size-1)
return self.pools[rnd_index]
# map the password by index
def generate(self):
rnd_chars = ''
i = 0
while i < self.length:
rnd_chars += self.fetch_one()
i += 1
return rnd_chars
if __name__ == '__main__':
try:
while True:
print('[-] [press `Ctrl+C` to cancel], default=24: ')
length = raw_input('Length to generate: ')
# python3
#length = input('Length: ')
if not length:
length = '24'
if length.isdigit():
print('\n\n{0}\n\n'.format(RandChars(int(length)).generate()))
else:
print('\n[WARNING] hi, length is digit.\n')
except KeyboardInterrupt:
print('\n\n[NOTICE] You cancelled the operation.\n')
except Exception as err:
print('\n[ERROR]: {0}\n'.format(err))
3、sendEmail
其他人写的脚本
[root@tvm-test ~]# sendEmail -s smtp.company.com \
-xu [email protected] \
-xp mail_password \
-f [email protected] \
-t [email protected] \
-u 'msg title' \
-m 'msg body' \
-a /tmp/p_w_upload.txt
