zabbix 自动化部署

zabbix 自动化部署主要指自动化的部署 zabbix agent 主机，由于 zabbix server主机或者 zabbix proxy 主机的数量往往比较少，而生产实践中要监控的主机往往很多，如果一台一台的安装 zabbix agent 则不现实，这时可以考虑使用脚本通过ssh 批量部署，或者使用 ansible 批量部署安装 zabbix agent。

编写脚本使用源码编译安装 zabbix agent

实验环境：这里用web的2台服务器 WEB-1 ：172.20.32.106和WEB-1 ：172.20.32.107
zabbix server ：172.20.32.101

基础命令：
# apt-get -y install iproute2 ntpdate tcpdump telnet traceroute nfs-kernel-server nfs-common lrzsz tree openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev ntpdate tcpdump telnet traceroute gcc openssh-server iotop unzip zip make

编写脚本

root@WEB-1:/usr/local/src# vim compile_install_zabbix.sh 
#!/bin/bash
#
WORK_DIR="/usr/local/src"
ZABBIX_VER="zabbix-4.0.20"

if [[ ! -e "${WORK_DIR}" ]]; then
    WORK_DIR=`pwd`
fi

## install some libs and deps.
if grep -iq "ubuntu" /etc/issue; then

    apt update
    apt -y install iproute2 ntpdate tcpdump telnet \
    traceroute nfs-kernel-server nfs-common lrzsz tree \
    openssl libssl-dev libpcre3 libpcre3-dev zlib1g-dev \
    ntpdate tcpdump telnet traceroute gcc openssh-server \
    iotop unzip zip make

else
    yum install -y vim iotop bc gcc gcc-c++ glibc glibc-devel \
    pcre  pcre-devel openssl  openssl-devel zip unzip zlib-devel\
    net-tools lrzsz tree ntpdate telnet lsof tcpdump wget libevent \
    libevent-devel bc systemd-devel bash-completion traceroute
fi

## compile zabbix and install
cd ${WORK_DIR}
tar -xf ${ZABBIX_VER}.tar.gz && \
            cd ${ZABBIX_VER} && \
            ./configure --prefix=/apps/zabbix_agent --enable-agent && \
            make && make install

## add user and create dir for pid file and log file
useradd zabbix
mkdir /apps/zabbix_agent/pid
mkdir /apps/zabbix_agent/logs

# copy conf file to the app folder
\cp ${WORK_DIR}/zabbix-agent.service    /lib/systemd/system/zabbix-agent.service
\cp ${WORK_DIR}/zabbix_agentd.conf      /apps/zabbix_agent/etc/zabbix_agentd.conf
\cp ${WORK_DIR}/zabbix_agentd.conf.d/*  /apps/zabbix_agent/etc/zabbix_agentd.conf.d/

## modify the zabbix hostname to ip.
HOST_IP=`ifconfig  eth0 | grep -w inet  | awk '{print $2}'`
sed -i "s/Hostname=/Hostname=${HOST_IP}/g" /apps/zabbix_agent/etc/zabbix_agentd.conf

chown zabbix.zabbix -R /apps/zabbix_agent/

systemctl daemon-reload
systemctl enable zabbix-agent
systemctl restart zabbix-agent

准备部署需要的文件

从原来的受 zabbix 监控的主机（在这里是172.20.32.105）将监控脚本和 agent 监控入口配置文件拷贝到新加的主机（172.20.32.106），此处为Mysql-slave：172.20.32.105原有的受监控主机，WEB-1：172.20.32.106为新加主机，这个新加的主机就是用来编写部署的所有准备文件以及安装包，到时候只要这个机器部署好了环境，就可以整体打包给其他机器进行批量部署。

从之前部署过的机器拷贝相关文件到新的部署机器

编写一键部署脚本

该脚本接收一个参数:$1，$1为主机 IP 列表，每个 IP 为一行的文本文件。主机列表文件和 zabbix agent 部署打包文件与该脚本在同一目录，直接运行该脚本，会首先分发公钥给对端主机，然后将 zabbix agent 部署文件发送到对端，再分别解压安装。

使用 ansible 批量部署

使用 ansible 将安装脚本和 zabbix 源码及配置文件等推送到远程主机，再通过 ansible 运行该编译脚本，批量部署 zabbix agent
这里把环境初始化一下，用172.20.32.107主机Ansible-server做控制端服务器

这些为部署的机器
172.20.32.108
172.20.32.109
172.20.32.110

1.将打包好的部署文件上传到 ansible 控制端:172.20.32.107

root@WEB-1:/usr/local/src# scp zabbix_agent_deploy.tar.gz 172.20.32.107:/usr/local/src

2.添加主机到 ansible 主机列表并测试是否可达

root@Ansible-server:/usr/local/src# apt update
root@Ansible-server:/usr/local/src# apt install software-properties-common
root@Ansible-server:/usr/local/src# apt-add-repository --yes --update ppa:ansible/ansible

root@Ansible-server:/usr/local/src# apt install ansible -y

root@Ansible-server:/usr/local/src# ssh-keygen
root@Ansible-server:/usr/local/src# ssh-copy-id 172.20.32.108
root@Ansible-server:/usr/local/src# ssh-copy-id 172.20.32.109
root@Ansible-server:/usr/local/src# ssh-copy-id 172.20.32.110

在ansible配置文件中添加部署的主机

# 添加主机
root@Ansible-server:/usr/local/src# vim /etc/ansible/hosts
[zabbix_agent]
172.20.32.108
172.20.32.109
172.20.32.110

# 测试是否可达
root@Ansible-server:/usr/local/src# ansible zabbix_agent -m ping
172.20.32.109 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    }, 
    "changed": false, 
    "ping": "pong"
}
172.20.32.108 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    }, 
    "changed": false, 
    "ping": "pong"
}
172.20.32.110 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    }, 
    "changed": false, 
    "ping": "pong"
}

3.编写 playbook

root@Ansible-server:/usr/local/src# vim deploy_zabbix_agent.yaml
root@Ansible-server:/usr/local/src# cat deploy_zabbix_agent.yaml
---
- hosts: zabbix_agent
  remote_user: root
  tasks:
    - name: unarchive zabbix_agent_deploy.tar.gz
      unarchive: src=/usr/local/src/zabbix_agent_deploy.tar.gz dest=/usr/local/src
    - name: run script to install and deploy zabbix agent
      shell: chdir=/usr/local/src ./compile_install_zabbix.sh

4.测试 playbook

root@Ansible-server:/usr/local/src# ansible-playbook -C deploy_zabbix_agent.yaml

5.部署

root@Ansible-server:/usr/local/src# ansible-playbook  deploy_zabbix_agent.yaml

root@Ansible-server:/usr/local/src# echo $?
0
