ansible实战__使用安装包安装nginx

目录结构

[root@master tar_install_nginx]# tree

文件解释

nginx-1.22.1.tar.gz

nginx安装包，其他版本也可以

nginx.service

为了设置系统启动（systemctl start nginx）等

具体文件

nginx_install_tar.yaml

自定义yum文件

- hosts: node2
  tasks:
    - name: 安装编译环境和依赖包
      yum:
        name:
          - gcc
          - gcc-c++
          - pcre
          - pcre-devel
          - zlib
          - zlib-devel
          - openssl
          - openssl-devel
    - name: 复制解压nginx安装包
      unarchive:
        src: ~/ansible/tar_install_nginx/nginx-1.22.1.tar.gz
        dest: ~/
    - name: 创建文件夹
      file:
        path: /usr/local/nginx
        state: directory
    - name: 安装nginx至/usr/local/nginx
      shell: cd /root/nginx-1.22.1;./configure --prefix=/usr/local/nginx && make && make install
    - name: 编写系统启动脚本
      template:
        src: nginx.service
        dest: /usr/lib/systemd/system/
    - name: 启动nginx服务
      service:
        name: nginx
        state: started
        enabled: yes
    - name: 打开80端口
      firewalld:
        port: 80/tcp
        permanent: yes
        immediate: yes
        state: enabled

检查yml文件格式是否正确，没有报错则没问题

[root@master yum_install_nginx]# ansible-playbook -i ../hosts nginx_install.yaml --syntax-check

playbook: nginx_install.yaml

查看操作哪些机器节点

[root@master yum_install_nginx]# ansible-playbook -i ../hosts nginx_install.yaml --list-hosts

playbook: nginx_install.yaml

  play #1 (node2): node2        TAGS: []
    pattern: [u'node2']
    hosts (1):
      node2

执行，注意yaml文件没有和主机清单文件在同一目录，需要指定主机清单文件路径

[root@master yum_install_nginx]# ansible-playbook -i ../hosts nginx_install.yaml
