2.所需jar包
参考⽂档
1.解压
tar -xvf docker-18.06.1-ce.tgz
2、将解压出来的docker⽂件内容移动到 /usr/bin/ ⽬录下
cp docker/* /usr/bin/
3.将docker注册为service
vim /etc/systemd/system/docker.service
将下列配置加到docker.service中并保存
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd --graph /home/docker ExecReload=/bin/kill -s HUP $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel. We recommend using cgroups to do container-local accounting. LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity # Uncomment TasksMax if your systemd version supports it. # Only systemd 226 and above support this version. #TasksMax=infinity TimeoutStartSec=0 # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process # restart the docker process if it exits prematurely Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target
4.启动
chmod +x /etc/systemd/system/docker.service #添加⽂件权限并启动docker systemctl daemon-reload #重载unit配置⽂件 systemctl start docker #启动Docker systemctl enable docker.service #设置开机⾃启
5.验证
systemctl status docker #查看Docker状态 docker version #查看Docker版本4.安装docker-compose
将docker-compose拷⻉到⽬标主机后，放⼊相应⽬录中，并修改权限
cp docker-compose /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose5.把server端所需jar包导入docker成为镜像 6.在docker-compose目录下新建文件夹，放入docker-compose.yml
注意： 此⽂件对格式要求⾮常严格，必须要缩进对⻬好
根据选⽤的镜像进⾏改写
需要修改的地⽅主要是 environment、image、volumes，如果默认端⼝被占⽤，可以修改端⼝。
如果使⽤https镜像，需要将ports 80:8080 改成 443:8443

7.启动服务
# 到docker-compose.yml所在的⽬录，运⾏ docker-compose up -d # 查看容器启动情况 docker ps -a8.页面访问 9.安装agent
1.所需包
2.下载安装好三个包
3.删除已经安装好的zabbix_agentd.conf,替换成上图的zabbix_agentd.conf
4.修改配置文件
5.重启服务
systemctl restart zabbix-agent10.告警配置
（1）安装mailx工具 yum -y install mailx
（2）配置zabbix服务器外部邮箱
vim /etc/mail.rc 打开文件
```javascript
set bsdcompat
set from=1136145321@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=1136145321@qq.com
set smtp-auth-password=drripjdxvotibaae
set smtp-auth=login
```
（3）测试发送邮件
```javascript
echo “this is test mail” | mail -s “text_mail” 473379613@qq.com
```
(补充知识)
重点
zabbix启动：
zabbix+docker (上面有)
zabbix 重要的几个部分
zabbix-server zabbix_server.conf
zabbix-agent zabbix_agent.conf
zabbix -proxy zabbix_agent.conf
11.ansible学习链接：https://www.cnblogs.com/keerya/p/7987886.html
步骤1：
安装ansible
1.安装epel-release
```javascript
yum install epel-release
```
2.安装ansible
yum install ansible
步骤2：
在server端生成密钥对 ssh-keygen -t rsa -f /root/.ssh/id_rsa -N ‘’
将公钥传输到被管理节点，建立信用关系
ssh-copy-id +主机ip或主机名
步骤3：
ping模块测试主机间的连通性
```javascript
ansible 192.168.91.142 -m ping (方法一)
ansible 192.168.91.142, -m ping 或 ansible 192.168.91.142,IP地址 -m ping （方法二）可多个ip测试ping
（在主机清单中需要配置该IP）
```
192.168.91.142 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
copy模块
touch /tmp/a.conf -- 创建一个文件
ansible 192.168.91.142 -m copy -a "src=/tmp/a.conf dest=/tem/a.conf" --执行将主机文件copy到指定主机ip的文件目录下
主机清单
1. 作用：一、用于读取主机ip或主机名称，二、实现主机分组
2.配置（vim /etc/ansible/hosts）：
(1)主机清单文件中添加ip或主机名
（2）在主机清单文件中添加一个分组，然后再添加ip或主机名到分组中
--列出所有清单ip ansible all -i /etc/ansible/hosts --list-hosts --列出组ip清单 ansible 组名 -i /etc/ansible/hosts --list-hosts
command 和 shell
