Posted 2022-05-06 清风明月li

安装ansible

nginx  yum install ansible -y

方法一、使用命令批量发送

SQL  1、创建相应的目录  mkdir -p /opt/node-export cd /opt/node-export/ 2、下载node-exporter和创建对应的启动文件  wget https://github.com/prometheus/node_exporter/releases/download/v1.3.1/node_exporter-1.3.1.linux-amd64.tar.gz tar xf node_exporter-1.3.1.linux-amd64.tar.gz node_exporter-1.3.1.linux-amd64/ 3、启动文件 cat node-exporter.service [Unit] Description=Prometheus node_exporter Requires=network.target remote-fs.target After=network.target remote-fs.target [Service] Type=simple User=root Group=root ExecStart=/opt/node_exporter/node_exporter --web.listen-address=0.0.0.0:9100 ExecReload=/bin/kill -HUP $MAINPID KillMode=process Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target 4、创建对应的ip地址 [root@k8s-master node-export]# cat iplist.txt [20220504] 172.16.5.122 172.16.5.146 5、远程拷贝文件 [root@k8s-master node-export]# ansible 20220504 -m copy -a "src=./node_exporter dest=/opt/node-exporter/  backup=yes" -i iplist.txt [WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details 172.16.5.122 | CHANGED =>     "ansible_facts":         "discovered_interpreter_python": "/usr/bin/python"     ,     "changed": true,     "checksum": "6b88b4e8e0b109cb70d0410fea7df35692fe1216",     "dest": "/opt/node-exporter/node_exporter",     "gid": 0,     "group": "root",     "md5sum": "e105cbe3e43cc6e133a83358db009d36",     "mode": "0644",     "owner": "root",     "size": 18228926,     "src": "/root/.ansible/tmp/ansible-tmp-1651660508.81-32118-215511342287544/source",     "state": "file",     "uid": 0 172.16.5.146 | CHANGED =>     "ansible_facts":         "discovered_interpreter_python": "/usr/bin/python"     ,     "changed": true,     "checksum": "6b88b4e8e0b109cb70d0410fea7df35692fe1216",     "dest": "/opt/node-exporter/node_exporter",     "gid": 0,     "group": "root",     "md5sum": "e105cbe3e43cc6e133a83358db009d36",     "mode": "0644",     "owner": "root",     "size": 18228926,     "src": "/root/.ansible/tmp/ansible-tmp-1651660508.8-32120-197167126853989/source",     "state": "file",     "uid": 0 6、发送服务自启动配置文件 [root@k8s-master node-export]# ansible 20220504 -m copy -a "src=./files/node-exporter.service  dest=/usr/lib/systemd/system/  backup=yes" -i iplist.txt [WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details 172.16.5.122 | CHANGED =>     "ansible_facts":         "discovered_interpreter_python": "/usr/bin/python"     ,     "changed": true,     "checksum": "8523709e50be5c4e1218feafa8b22baf30e5e682",     "dest": "/usr/lib/systemd/system/node-exporter.service",     "gid": 0,     "group": "root",     "md5sum": "2168230bbf44d0bf8bff4539bce3a357",     "mode": "0644",     "owner": "root",     "size": 367,     "src": "/root/.ansible/tmp/ansible-tmp-1651660799.58-4285-252476952854520/source",     "state": "file",     "uid": 0 7、创建自启动文件 [root@k8s-master node-export]# ansible 20220504 -m shell -a "systemctl enable node-exporter.service" -i iplist.txt [WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details 172.16.5.146 | CHANGED | rc=0 >> Created symlink from /etc/systemd/system/multi-user.target.wants/node-exporter.service to /usr/lib/systemd/system/node-exporter.service. 172.16.5.122 | CHANGED | rc=0 >> Created symlink from /etc/systemd/system/multi-user.target.wants/node-exporter.service to /usr/lib/systemd/system/node-exporter.service. 8、赋权限 [root@k8s-master node-export]# ansible 20220504 -m shell -a "chmod 755 /opt/node-exporter/node_exporter" -i iplist.txt 9、自启动文件 [root@k8s-master node-export]# ansible 20220504 -m shell -a "systemctl start node-exporter.service" -i iplist.txt  [WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details 172.16.5.146 | CHANGED | rc=0 >> 172.16.5.122 | CHANGED | rc=0 >>

方法二、ansible 部署Prometheus node_exporter通过playbook

1、编写site.yaml文件

YAML 1、创建工作目录 [root@k8s-master ~]# mkdir -p /opt/node-export [root@k8s-master ~]# cd /opt/node-export/ 2、配置site.yaml [root@k8s-master node-export]# cat  site.yaml - hosts: node-exporter   tasks:     - name: copy node_exporter       copy:         src: /opt/node-export/node_exporter         dest: /opt/node-exporter/         owner: root         group: root         mode: 755     - name: copy node-exporter.service       copy:         src: files/node-exporter.service         dest: /usr/lib/systemd/system/       notify:         - call restart service     - name: 开机自启动       shell: systemctl enable node-exporter.service     - name: 启动服务       shell: systemctl start node-exporter.service

2、创建node_exporter二进制文件和相关的配置

2.1、创建目录files

CoffeeScript [root@k8s-master node-export]# mkdir files [root@k8s-master node-export]# cd files/ [root@k8s-master files]#wget  https://github.com/prometheus/node_exporter/releases/download/v1.3.1/node_exporter-1.3.1.linux-amd64.tar.gz

备注:files文件里面包含node_exporter二进制文件；开机自启文件node-exporter.service；node_exporter开机自启服务自定义端口配置node-exporter

2.2、编辑node_exporter开机自启动服务等配置文件

Makefile [root@k8s-master node-export]# cat  files/node-exporter.service [Unit] Description=Prometheus node_exporter Requires=network.target remote-fs.target After=network.target remote-fs.target [Service] Type=simple User=root Group=root ExecStart=/opt/node_exporter/node_exporter --web.listen-address=0.0.0.0:9100 ExecReload=/bin/kill -HUP $MAINPID KillMode=process Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target

2.3、给/etc/ansible/hosts添加所有的主机

CoffeeScript [root@k8s-master node-export]# vim /etc/ansible/hosts [node-exporter] 172.16.5.122 172.16.5.146

2.4、执行ansible-playbook

Go [root@k8s-master node-export]# ansible-playbook site.yaml
