django集成ansibe实现自动化
动态生成主机列表和相关参数
def create_admin_domain(admin_node): workpath = BASE_DIR + '/tools/ansible/script' hosts_file = BASE_DIR + '/tools/ansible/host/' + createhostfile() yml_file = BASE_DIR + '/tools/ansible/yml/' + 'create_admin_domain.yml' domain_path = admin_node.domainpath app_server_name=admin_node.app_server_name host_ip = admin_node.asset_ip ansible_ssh_user = admin_node.username ansible_ssh_pass = admin_node.password with open(hosts_file, 'w+') as f: f.writelines('[app_admin_domain]\n') domain_args = "%s-%s ansible_host=%s ansible_ssh_user=%s ansible_ssh_pass=%s domain_path=%s\n" % ( host_ip,app_server_name,host_ip, ansible_ssh_user, ansible_ssh_pass, domain_path) f.writelines(domain_args) cmd = 'ansible-playbook -i %s %s --extra-vars "workpath=%s"' % (hosts_file, yml_file, workpath) print(cmd) p = Popen(cmd, stderr=PIPE, stdout=PIPE, shell=True) data = p.communicate() if p.returncode == 0: print("执行成功") else: print("执行失败")
[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
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
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=0755 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
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)
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 !>
