[app_admin_domain]
10.199.137.5-itsgl ansible_host=10.199.137.5 ansible_ssh_user=weblogic ansible_ssh_pass=weblogic domain_path=/its/weblogic/user_projects/domains/itsgl_domain
生成结果
动态生成ansible的主机文件的时候 要注意主机别名在不同的主机清单文件中不能重复 否则只会执行第一个主机清单 后面的清单文件不会被执行
with open(hosts_file, 'w+') as f:
f.writelines('[app_jmsmodule_servernode]\n')
data_args="%s-jmsmodule-%s ansible_host=%s ansible_ssh_user=%s ansible_ssh_pass=%s" \
" ip=%s port=%s datafile=%s\n" %(
host_ip,generate_random_str(6),host_ip,ansible_ssh_user,ansible_ssh_pass,
host_ip,port,jms.datafile
) #%s-jmsmodule-%s 代表别名字符串 生成的字符串在每个hosts文件中必须是唯一的
编写yml文件

问题
1.you must install the sshpass program
只需要安装sshpass即可，CentOS系统的默认yum源里面并没有这个软件
在ansible主机上安装好即可 $ wget http://sourceforge.net/projects/sshpass/files/latest/download -O sshpass.tar.gz
$ tar -xvf sshpass.tar.gz
$ cd sshpass-1.06
$ ./configure
$ sudo make install
2.Failed to connect to the host via ssh: ssh: Could not resolve hostname ansible_host=10.199.137.5: Name or service not known
在执行ansible或者ansible-playbook命令的时候 不能直接指定IP地址 必须使用别名
[beijing]
1.1.1.1-aa ansible_host=1.1.1.1
1.1.1.2-bb ansible_host=1.1.1.2
1.1.1.3-cc ansible_host=1.1.1.3 [root]# ansible beijing -m ping
1.1.1.1-aa | SUCCESS => {
"changed": false,
"ping": "pong"
}
1.1.1.3-bb | SUCCESS => {
"changed": false,
"ping": "pong"
}
1.1.1.2-cc | SUCCESS => {
"changed": false,
"ping": "pong" 单独使用host里1.1.1.1这个IP会显示没有符合
[root@ansible ansible]# ansible 1.1.1.1 -m ping
[WARNING]: Could not match supplied host pattern, ignoring: 1.1.1.1 需要使用别名才能正常运行
[root@ansible ansible]# ansible 1.1.1.1-aa -m ping
1.1.1.1-aa | SUCCESS => {
"changed": false,
"ping": "pong"
} 这就要求我们在动态生成主机清单文件的时候必须生成一个别名 否则会出现异常
格式如下 10.199.137.5-itsgl就是一个别名字符串
10.199.137.5-itsgl ansible_host=10.199.137.5
别名解决方案
3.ansible playbook判断指定的目录或者文件是否存在
---
- hosts: app_server_domain
tasks:
- name: check {{domain_path}} is exits
shell: ls {{domain_path}}
ignore_errors: True
register: result
- name: mkdir {{domain_path}} directory
file: path={{domain_path}}/ state=directory mode=
when: result|failed
- name: copy mb file to {{domain_path}}
copy: src={{local_file}}/ dest={{domain_path}} backup=yes
when: result|failed
- name: excute cpdomain shell
shell: sh {{domain_path}}/cpdomain.sh
when: result|failed
yml语法
ansible 的常用模块中没有判定当文件存在或者不存在时执行某个命令 --- - name: judge a file or dir is exits
shell: ls /home/sfy
ignore_errors: True
register: result - shell: echo "file exit"
when: result|succeeded - shell: echo "file not exit"
when: result|failed
django把复杂数据结构参数传递给后台脚本
1.由django把数据内容写入指定的文件
2.调用脚本的时候把文件路径传递给脚本
3.脚本读取指定路径的文件内容
with open(jms.datafile,'w+') as f:
dict={}
dict["name"]=jms.jmsmodule_name
dict["resources"]=[]
resourcelist=JmsModuleSet.objects.all().filter(jmsmodule=jms.id)
for res in resourcelist:
dict["resources"].append({"resourcename":res.resource_name,"type":res.jmsmoduleset_type})
dict["targets"]=[]
taglist=jms.server_list.all()
for tag in taglist:
dict["targets"].append(tag.app_server_name)
f.write(str(dict))
writelogfile(jms.deploylogfile,"%s 写内容入完毕" %jms.datafile)
views中被内容写入文件
import os def create_jmsmodule(ip,port,filename):
f = open(filename, "r")
re = f.read()
jsmodule = eval(re)
f.close() wls:/itsgl_domain/edit !> f=open("/wlst/jmsmodule_data","r")
wls:/itsgl_domain/edit !> re=f.read()
wls:/itsgl_domain/edit !> print re
{'resources': [{'resourcename': 'aa1111', 'type': 'queue'}, {'resourcename': 'aaa2', 'type': 'connectFactory'}], 'targets': ['wtjscxnw', 'wtmhnw'], 'name': 'aaaa'}
wls:/itsgl_domain/edit !> obj=eval(re)
wls:/itsgl_domain/edit !> print obj
{'targets': ['wtjscxnw', 'wtmhnw'], 'name': 'aaaa', 'resources': [{'type': 'queue', 'resourcename': 'aa1111'}, {'type': 'connectFactory', 'resourcename': 'aaa2'}]}
wls:/itsgl_domain/edit !>
脚本读取文件内容
def jms_add(request):
apps_id = request.GET.get('mid', '')
jmsobj= JmsModule.objects.filter(id=apps_id)[0]
if request.POST:
apps_form = JmsModuleSetForm(request.POST)
apps_form.instance.jmsmodule=jmsobj
