ansible批量安裝node-exporter

安裝ansible

Nginx  yum install ansible -y

方法一、使用指令批量發送

SQL  1、建立相應的目錄  mkdir -p /opt/node-export cd /opt/node-export/ 2、下載下傳node-exporter和建立對應的啟動檔案  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、啟動檔案 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、建立對應的ip位址 [root@k8s-master node-export]# cat iplist.txt [20220504] 172.16.5.122 172.16.5.146 5、遠端拷貝檔案 [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、發送服務自啟動配置檔案 [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、建立自啟動檔案 [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、賦權限 [root@k8s-master node-export]# ansible 20220504 -m shell -a "chmod 755 /opt/node-exporter/node_exporter" -i iplist.txt 9、自啟動檔案 [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通過playbook

1、編寫site.yaml檔案

YAML 1、建立工作目錄 [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: 開機自啟動       shell: systemctl enable node-exporter.service     - name: 啟動服務       shell: systemctl start node-exporter.service

2、建立node_exporter二進制檔案和相關的配置

2.1、建立目錄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

備注:files檔案裡面包含node_exporter二進制檔案；開機自啟檔案node-exporter.service；node_exporter開機自啟服務自定義端口配置node-exporter

2.2、編輯node_exporter開機自啟動服務等配置檔案

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、給/etc/ansible/hosts添加所有的主機

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

2.4、執行ansible-playbook

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