集群运维自动化工具ansible之使用playbook安装zabbix客户端

技术  /  管理员 发布于 7年前   148

之前介绍了关于ansible的安装与使用（包括模块与playbook使用，地址是///article/52154.htm），今天介绍一下如何使用playbook来部署zabbix客户端。
ansible服务端的环境为centos 6.5 x86_64系统
ansible客户端环境为centos 6.3 x86_64系统
目前我的playbook只允许centos或redhat 6系列系统来安装zabbix客户端，并且客户端的版本是2.0.6.
下面是playbook的结构

14:29:30 # pwd/etc/ansible/rolesroot@ip-10-10-10-10:/etc/ansible/roles14:29:37 # tree zabbix_client_*zabbix_client_delete  删除已经安装的zabbix客户端├── files      存放文件的├── handlers    重启的东东├── meta      galaxy_info的信息│  └── main.yml  ├── tasks      操作的任务流程│  ├── delete.yml │  └── main.yml├── templates    模板└── vars      变量  └── main.ymlzabbix_client_install├── files│  └── zabbix-2.0.6.tar.gz├── handlers├── meta│  └── main.yml├── tasks│  ├── copy.yml│  ├── delete.yml│  ├── install.yml│  └── main.yml├── templates│  ├── zabbix_agentd│  └── zabbix_agentd.conf└── vars  └── main.yml 12 directories, 13 files

下面是先介绍一下安装方面zabbix_client_install的内容
1、galaxy_info的信息

14:32:15 # cat /etc/ansible/roles/zabbix_client_install/meta/main.yml galaxy_info: author: Deng Lei description: Install Zabbix Client  license: MIT min_ansible_version: 1.6 platforms: - name: CentOS  versions:  - 6 categories: - Monitordependencies: []

2、task里的copy.xml信息

14:33:35 # cat /etc/ansible/roles/zabbix_client_install/tasks/copy.yml  - name: Stop Exist Zabbix Client Service In Redhat Client  shell: ps -ef|grep zabbix|grep -v grep|awk '{print $2}'|xargs kill -9 >>/dev/null 2>&1  ignore_errors: yes  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Delete Exist Zabbix Client Dir In Redhat Client  shell: rm -rf {{ zabbix_dir }}/zabbix  ignore_errors: yes  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Install Base Require Software In Redhat Client  yum: name={{ item }} state=latest  with_items:   - telnet   - dmidecode   - tar - name: Create Zabbix User In Redhat Client  user: name={{ zabbix_user }} state=present createhome=no shell=/sbin/nologin  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Copy Zabbix Client Software To Redhat Client  copy: src=zabbix-{{ zabbix_version }}.tar.gz dest=/tmp/zabbix-{{ zabbix_version }}.tar.gz owner=root group=root  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Uncompression Zabbix Client Software To Redhat Client  shell: tar zxf /tmp/zabbix-{{ zabbix_version }}.tar.gz -C {{ zabbix_dir }}/  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Copy Zabbix Start Script To Redhat Client  template: src=zabbix_agentd dest=/etc/init.d/zabbix_agentd owner=root group=root mode=0755  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Copy Zabbix Config To Redhat Client  template: src=zabbix_agentd.conf dest={{ zabbix_dir }}/zabbix/conf/zabbix_agentd.conf owner={{ zabbix_user }} group={{ zabbix_user }} mode=0644  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件是复制对应的文件到客户端

3、task的install.yml信息

14:34:26 # cat /etc/ansible/roles/zabbix_client_install/tasks/install.yml  - name: Modify Zabbix Dir Permission In Redhat Client  file: path={{ zabbix_dir }}/zabbix owner={{ zabbix_user }} group={{ zabbix_user }} mode=0755  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Check Zabbix User Sudo Permission In Redhat Client  shell: grep "{{ zabbix_user }}" /etc/sudoers|wc -l  register: zabbix_sudoer  ignore_errors: True  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Give Sudo Permission To Zabbix User In Redhat Client  shell: echo "{{ zabbix_user }} ALL=(root) NOPASSWD:/bin/netstat, /usr/bin/omreport" >> /etc/sudoers  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 and zabbix_sudoer|int ==0 - name: Start Zabbix Service In Redhat Client  shell: /etc/init.d/zabbix_agentd start  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6 - name: Add Boot Start Zabbix Service In Redhat Client  shell: chkconfig --level 345 zabbix_agentd on  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件主要是安装

4、tasks的delete.yml信息

14:35:08 # cat /etc/ansible/roles/zabbix_client_install/tasks/delete.yml  - name: Delete Zabbix compression Software In Redhat Client  shell: rm -rf /tmp/zabbix-{{ zabbix_version }}.tar.gz  when: ansible_os_family == "RedHat" and ansible_lsb.major_release|int == 6

此文件是安装完成后，删除安装前的文件

5、tasks的mail.yml

14:35:37 # cat /etc/ansible/roles/zabbix_client_install/tasks/main.yml - include: copy.yml- include: install.yml- include: delete.yml

此文件是允许运行哪个文件

6、templates的zabbix_agentd

15:15:45 # cat /etc/ansible/roles/zabbix_client_install/templates/zabbix_agentd#!/bin/bash## chkconfig: - 85 15# description: Zabbix client script.# processname: Zabbix. /etc/profile SERVICE="Zabbix agent"DAEMON={{ zabbix_dir }}/zabbix/sbin/zabbix_agentdPIDFILE=/tmp/zabbix_agentd.pidCONFIG={{ zabbix_dir }}/zabbix/conf/zabbix_agentd.confzabbix_agent_status=`ps aux|grep zabbix_agentd.conf|grep -v grep|wc -l`zabbix_agent_pid=`ps aux|grep zabbix_agentd|grep -v grep|awk 'NR==1{print $2}'`# Source function library.. /etc/rc.d/init.d/functions# Source networking configuration.. /etc/sysconfig/networkfunction check(){if [ $? -eq 0 ];then  action $"Operating is:" /bin/trueelse  action $"Operating is:" /bin/falsefi}case $1 in 'start')  if [ -x ${DAEMON} ]  then   $DAEMON -c $CONFIG   # Error checking here would be good...   echo "${SERVICE} started."  else   echo "Can't find file ${DAEMON}."   echo "${SERVICE} NOT started."  fi  check ;;  'stop')  if [ -s ${PIDFILE} ]  then   if kill `cat ${PIDFILE}` >/dev/null 2>&1   then    echo "${SERVICE} terminated."    rm -f ${PIDFILE}   fi  fi  check ;; 'restart')  /bin/bash $0 stop  sleep 5  /bin/bash $0 start ;;  'status')  if [ $zabbix_agent_status -ne 0 ];then    echo "Zabbix Agentd is running ($zabbix_agent_pid)"  else    echo "Zabbix Agentd is not running!"  fi  ;; *)  echo "Usage: $0 {start|stop|status|restart}";; esacexit 0

这个文件是启动客户端的脚本

7、templates的zabbix_agentd.conf

15:16:36 # cat /etc/ansible/roles/zabbix_client_install/templates/zabbix_agentd.conf # This is a config file for the Zabbix agent daemon (Unix)# To get more information about Zabbix, visit http://www.zabbix.com ############ GENERAL PARAMETERS ################# ### Option: PidFile#  Name of PID file.## Mandatory: no# Default:# PidFile=/tmp/zabbix_agentd.pid ### Option: LogFile#  Name of log file.#  If not set, syslog is used.## Mandatory: no# Default:# LogFile= LogFile=/tmp/zabbix_agentd.log ### Option: LogFileSize#  Maximum size of log file in MB.#  0 - disable automatic log rotation.## Mandatory: no# Range: 0-1024# Default:# LogFileSize=1 ### Option: DebugLevel#  Specifies debug level#  0 - no debug#  1 - critical information#  2 - error information#  3 - warnings#  4 - for debugging (produces lots of information)## Mandatory: no# Range: 0-4# Default:# DebugLevel=3 ### Option: SourceIP#  Source IP address for outgoing connections.## Mandatory: no# Default:# SourceIP= ### Option: EnableRemoteCommands#  Whether remote commands from Zabbix server are allowed.#  0 - not allowed#  1 - allowed## Mandatory: no# Default:# EnableRemoteCommands=0 ### Option: LogRemoteCommands#  Enable logging of executed shell commands as warnings.#  0 - disabled#  1 - enabled## Mandatory: no# Default:# LogRemoteCommands=0 ##### Passive checks related ### Option: Server#  List of comma delimited IP addresses (or hostnames) of Zabbix servers.#  Incoming connections will be accepted only from the hosts listed here.#  No spaces allowed.#  If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally.## Mandatory: no# Default:# Server=zabbix-server-external.autoclouds.net Server={{ zabbix_server_ip }} ### Option: ListenPort#  Agent will listen on this port for connections from the server.## Mandatory: no# Range: 1024-32767# Default:ListenPort={{ zabbix_port }} ### Option: ListenIP#  List of comma delimited IP addresses that the agent should listen on.#  First IP address is sent to Zabbix server if connecting to it to retrieve list of active checks.## Mandatory: no# Default:# ListenIP=0.0.0.0 ### Option: StartAgents#  Number of pre-forked instances of zabbix_agentd that process passive checks.#  If set to 0, disables passive checks and the agent will not listen on any TCP port.## Mandatory: no# Range: 0-100# Default:# StartAgents=3 ##### Active checks related ### Option: ServerActive#  List of comma delimited IP:port (or hostname:port) pairs of Zabbix servers for active checks.#  If port is not specified, default port is used.#  IPv6 addresses must be enclosed in square brackets if port for that host is specified.#  If port is not specified, square brackets for IPv6 addresses are optional.#  If this parameter is not specified, active checks are disabled.#  Example: ServerActive=127.0.0.1:20051,zabbix.domain,[::1]:30051,::1,[12fc::1]## Mandatory: no# Default:# ServerActive= ### Option: Hostname#  Unique, case sensitive hostname.#  Required for active checks and must match hostname as configured on the server.#  Value is acquired from HostnameItem if undefined.## Mandatory: no# Default:# Hostname= Hostname={{ ansible_hostname }} ### Option: HostnameItem#  Item used for generating Hostname if it is undefined.#  Ignored if Hostname is defined.## Mandatory: no# Default:# HostnameItem=system.hostname ### Option: RefreshActiveChecks#  How often list of active checks is refreshed, in seconds.## Mandatory: no# Range: 60-3600# Default:# RefreshActiveChecks=120 ### Option: BufferSend#  Do not keep data longer than N seconds in buffer.## Mandatory: no# Range: 1-3600# Default:# BufferSend=5 ### Option: BufferSize#  Maximum number of values in a memory buffer.

此文件是客户端的配置文件
8、vars的main.yml

15:17:06 # cat /etc/ansible/roles/zabbix_client_install/vars/main.yml zabbix_dir: /usr/local      客户端安全目录zabbix_version: 2.0.6      客户端软件版本zabbix_user: zabbix       客户端用户zabbix_port: 10050        客户端的端口zabbix_server_ip: 192.168.1.10  zabbix_server的ip

此文件是配置变量的

9、ansible安装zabbix客户端的playbook配置文件zabbix_client_install.yml

15:20:02 # cat /etc/ansible/zabbix_client_install.yml ---- hosts: "{{host}}" remote_user: "{{user}}" gather_facts: True roles:  - zabbix_client_install

10、使用playbook安装zabbix客户端

我的测试客户端环境是centos 6.3，ip是192.168.240.17，使用key登陆

15:22:01 # cd /etc/ansible/root@ip-10-10-10-10:/etc/ansible15:22:04 # time ansible-playbook zabbix_client_install.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem  PLAY [192.168.240.17] *********************************************************  GATHERING FACTS *************************************************************** ok: [192.168.240.17] TASK: [zabbix_client_install | Stop Exist Zabbix Client Service In Redhat Client] *** failed: [192.168.240.17] => {"changed": true, "cmd": "ps -ef|grep zabbix|grep -v grep|awk '{print $2}'|xargs kill -9 >>/dev/null 2>&1 ", "delta": "0:00:00.018213", "end": "2014-07-10 07:22:34.793910", "item": "", "rc": 123, "start": "2014-07-10 07:22:34.775697"}...ignoring TASK: [zabbix_client_install | Delete Exist Zabbix Client Dir In Redhat Client] *** changed: [192.168.240.17] TASK: [zabbix_client_install | Install Base Require Software In Redhat Client] *** ok: [192.168.240.17] => (item=telnet,dmidecode,tar) TASK: [zabbix_client_install | Create Zabbix User In Redhat Client] *********** changed: [192.168.240.17] TASK: [zabbix_client_install | Copy Zabbix Client Software To Redhat Client] *** changed: [192.168.240.17] TASK: [zabbix_client_install | Uncompression Zabbix Client Software To Redhat Client] *** changed: [192.168.240.17] TASK: [zabbix_client_install | Copy Zabbix Start Script To Redhat Client] ***** changed: [192.168.240.17] TASK: [zabbix_client_install | Copy Zabbix Config To Redhat Client] *********** changed: [192.168.240.17] TASK: [zabbix_client_install | Modify Zabbix Dir Permission In Redhat Client] *** ok: [192.168.240.17] TASK: [zabbix_client_install | Check Zabbix User Sudo Permission In Redhat Client] *** changed: [192.168.240.17] TASK: [zabbix_client_install | Give Sudo Permission To Zabbix User In Redhat Client] *** changed: [192.168.240.17] TASK: [zabbix_client_install | Start Zabbix Service In Redhat Client] ********* changed: [192.168.240.17] TASK: [zabbix_client_install | Add Boot Start Zabbix Service In Redhat Client] *** changed: [192.168.240.17] TASK: [zabbix_client_install | Delete Zabbix compression Software In Redhat Client] *** changed: [192.168.240.17] PLAY RECAP ******************************************************************** 192.168.240.17       : ok=15  changed=12  unreachable=0  failed=0   real  0m39.888suser  0m1.547ssys 0m0.197s

可以看到39秒就安装完成，主要花费时间比较长的地方是fact收集、yum安装、文件传输。

11、测试安装情况

可以看到安装后的客户端，完全是按照我的要求来做的。

12、删除已经安装的客户端
