使用Ansible自动配置Nginx服务

1、首先安装好Ansible环境，具体步骤请见Ansible安装

2、先创建hosts文件（为后面编写脚本安装JDK做铺垫）

[root@localhost /]# vi hosts

[jdktest]

192.168.186.133 ansible_ssh_user=guxiong ansible_ssh_pass=private
192.168.186.134 ansible_ssh_user=guxiong ansible_ssh_pass=private 

注：记得/etc/ansible/hosts也要加入

3、创建文件夹

[root@localhost /]#  

makedir roles

       nginx-install

             default  

             files

                   ngnix-install         

                       

                 nginx-install.tar.gz

          handler

          meta

          tasks    main.yml

          templates  install-nginx.sh   nginx.conf

          vars   main.yml

4、编辑tasks下面的main.yml

 - name: create direc
    shell: mkdir -p {{ nginx_path }}
  - name: copy nginx file to remote client
    copy: src=nginx-install.tar.gz dest=/home/{{ user }}
  - name: untar nginx
    shell: tar -zxf nginx-install.tar.gz
  - name: configure install-nginx.sh user template
    template: src=install-nginx.sh dest=/home/{{ user }}/nginx-install/install-nginx.sh
  - name: cd install direc and excu install
    shell: cd /home/{{ user }}/nginx-install && sh install-nginx.sh
  - name: configure nginx.conf use template
    template: src=nginx.conf dest={{ nginx_path }}/conf/nginx.conf
  - name: rm nginxfiles
    shell: rm -rf /home/{{ user }}/nginx-install*

5、编辑templates下的 install-nginx.sh

#!/bin/bash

mkdir -p {{ nginx_path }}
cd nginx-1.9.3-hide-version
./configure --prefix={{ nginx_path }} --with-http_ssl_module --with-http_gunzip_module --with-http_stub_status_module --with-http_gzip_static_module --with-zlib=../zlib-1.2.8 --with-pcre=../pcre-8.38 --add-module=../nginx_upstream_check_module-master --add-module=../ngx_cache_purge-2.3  && make && make install
sleep 6
exit 0

6、将使用到的变量编辑vars下的main.yml

user: guxiong
nginx_host: 192.168.186.134
nginx_port: 3080
nginx_path: /home/guxiong/nginx1.9.0

7、ansible-playbook安装　　

[root@localhost /]# ansible-playbook nginx-install.yml --extra-var "host_cluster=jdktest user=guxiong nginx_host=192.168.186.134 nginx_port=3080 nginx_path=/home/guxiong/nginx1.9.0"
