ansible 批量安装zabbix-agent

服务器初始化（这是在建立在新的服务器基础上做的初始化）关闭防火墙、selinux，添加epel常用源，安装常用工具、添加普通用户并禁止root

 1、服务器批量初始化

[root@fwd ansible]# cat init.yml  系统初始化脚本
---
- hosts: all

  tasks: 
    - name: disable selinux、firewalls,replace ali sources
      shell: |
        sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
        systemctl disable firewalld
        mkdir -p /etc/yum.repos.d/backup
        mv /etc/yum.repos.d/* /etc/yum.repos.d/backup/
        curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

    - name: ensure a list of packages installed
      yum:
        name: "{{ packages }}"
      vars:
        packages:
        - wget
        - vim
        - sysstat
        - lrzsz
        - lsof

    - name: Add the user centos 
      user:
        name: centos 
        group: wheel

    - name:  disabled root remote login
      replace:
        path: /etc/ssh/sshd_config
        regexp: '\#PermitRootLogin yes'
        replace: 'PermitRootLogin no'
        backup: yes

    - name: modify ssh port
      shell: sed -i '/^\#Port/a\Port 22201' /etc/ssh/sshd_config

    - name: restart ssh
      service:
        name: sshd
        state: restarted

    - name: Add epel and reboot server
      shell: |
        reboot

 2、检测语法

[root@fwd ansible]# ansible-playbook -C init.yml

3、mysql 安装，并创建zabbix 需要数据库

[root@fwd ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
[root@fwd ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

 报错Percona-Release YUM存储库 -  x86_64”存储库列出的GPG密钥已经安装！
 解决办法如下：
[root@fwd ~]# yum update percona-release 
[root@fwd ~]# systemctl start mysqld

3.1、修改mysql 密码　授权zabbix用户

[root@fwd ~]# mysql_secure_installatio 
[root@fwd ~]# mysqladmin -u root password "123456";  2中方法随意
[root@fwd ~]# mysql -uroot -p
Enter password:
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '123456';
mysql> quit;

3.2、安装zabbix 4.0 server 添加zabbix 4.0 存储库， 并使用mysql 支持zabbix前端

[root@fwd ~]# yum install -y https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm
[root@fwd ~]# yum install -y zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-get

3.3、导入表结构

 

[root@fwd ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

 

3.4、修改配置文件

编辑 /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Europe/Riga  修改为 php_value date.timezone Asia/Shanghai
编辑 /etc/zabbix/zabbix_server.conf
DBPassword=123456

3.5、开启服务，并设置开机自启

[root@fwd ~]# systemctl restart zabbix-server zabbix-agent httpd
[root@fwd ~]# systemctl enable zabbix-server zabbix-agent httpd

4、批量部署zabbix-agent 客户端

 

[root@fwd ansible]# pwd
/etc/ansible
[root@fwd ansible]# tree
.

├── comon_site.retry
├── comon_site.yml

│       │   └── main.yml
│       └── templates
│           └── zabbix_agentd.conf.j2

4.1、查看hosts 文件　　

[root@fwd ansible]# cat hosts
[james]
192.168.9.22
192.168.9.132
192.168.9.14

 

[root@fwd ansible]# cat zabbix_agent.yml   
- hosts: all
  user: root
  vars:
     zabbix_serverip: 192.168.9.129 # zabbix 服务器IP
     zabbix_activeip: 192.168.9.129 # zabbix 服务器IP
     agent_hostname: '{{ ansible_hostname }}' # 客户端hostname
     agent_ip: '{{ ansible_ens33.ipv4.address }}' # 客户端IP 根据实际情况修改自己的网卡名字ens33 改成自己服务器
  roles:
    - zabbix_agent

4.2、在/etc/ansible/roles/zabbix_agent/ 创建tasks 目录　添加 main.yml 文件

 

[root@fwd tasks]# cat main.yml   # 这里写的是zabbix-agent 安装剧本
- name: copy zabbix_agentd 
  copy: src=/etc/ansible/roles/zabbix_agent/files/zabbix-agent-4.0.2-1.el7.x86_64.rpm dest=/usr/local/src/zabbix-agent-4.0.2-1.el7.x86_64.rpm
- name: install zabbix-agend
  shell: rpm -ivh /usr/local/src/zabbix-agent-4.0.2-1.el7.x86_64.rpm # 安装zabbix agentd
- name: up zabbix-agent file client  # 上传配置文件
  template: src=zabbix_agentd.conf.j2 dest=/etc/zabbix/zabbix_agentd.conf
- name: enabled service zabbix-agent # 打开zabbix-agent 开机启动
  service: name=zabbix-agent enabled=yes
- name: start  service zabbix-agent # 启动zabbix-agent
  service: name=zabbix-agent  state=started

 

4.3、在/etc/ansible/roles/zabbix_agent/ 下创建 templates 文件，定义zabbix_agent.conf .js模板文件

[root@fwd templates]# cat zabbix_agentd.conf.j2 
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
EnableRemoteCommands=1  #远程执行命令的选项
Server={{zabbix_serverip}} #自定义server IP 变量
ListenPort=10050
ServerActive={{zabbix_activeip}}
Hostname={{ansible_hostname}}  #自定义主机名变量
AllowRoot=1
UnsafeUserParameters=1   #设置为1 表示允许用户自定义key值
HostMetadataItem=system.uname
Include=/etc/zabbix/zabbix_agentd.d/*.confgather_facts: false

5、执行批量安装　　

 

[root@fwd ansible]# ansible-playbook zabbix_agent.yml

检查客户端zabbix_agent服务是否启动

5.1、这里介绍下忘记zabbix 登录密码怎么办，因为我经常忘记 查看md5秘钥

[root@fwd templates]# mysql -uroot -p -e "select * from zabbix.users\G"
Enter password: 
*************************** 1. row ***************************
        userid: 1
         alias: Admin
          name: Zabbix
       surname: Administrator
        passwd: 5fce1b3e34b520afeffb37ce08c7cd66
           url: 
     autologin: 1
    autologout: 0
          lang: en_GB
       refresh: 30s
          type: 3
         theme: default
attempt_failed: 0
    attempt_ip: 
 attempt_clock: 0
 rows_per_page: 50
*************************** 2. row ***************************
        userid: 2
         alias: guest
          name: 
       surname: 
        passwd: d41d8cd98f00b204e9800998ecf8427e
           url: 
     autologin: 0
    autologout: 15m
          lang: en_GB
       refresh: 30s
          type: 1
         theme: default
attempt_failed: 0
    attempt_ip: 
 attempt_clock: 0
 rows_per_page: 50　　
[root@fwd templates]# mysql -uroot -p
Enter password:
    mysql>use zabbix ;  进入到zabbix数据库
    mysql>update users set passwd='5fce1b3e34b520afeffb37ce08c7cd66' where userid='1';
    因为5fce1b3e34b520afeffb37ce08c7cd66 = zabbix  你现在就可以用 Admin zabbix 登录了~

6、zabbix自动发现，自动添加（我们批量安装zabbix_agent的目的就是因为以后服务器越来越多，面对越来越多的服务器，我们一台一台添加明显有点不现实！所以就要用到zabbix的自动发现登录zabbix http://localhost/zabbix）　　

6.1、配置自动发现规则

6.2、配置-动作-触发器-创建动作

6.3、配置完毕，几分钟后zabbix--监控中--自动发现

6.4、自动注册 配置-动作-自动注册

更新过后，刷新就会发现发现的主机已经自动添加了

报错主机无法被监控是因为我客户端防火墙开启了，没对外开放10050端口，给防火墙添加条规则就可以

[root@proxy-01 network-scripts]# cat /etc/sysconfig/iptables
# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
