使用Ansible部署Nginx

2017-07-20 00:30 381 查看

基于学习的目的，演示使用ansible往远程linux服务器上部署nginx。

创建playbook相关目录和文件

mkdir ansible-study
mkdir -p ansible-study/files
mkdir -p ansible-study/templates
touch ansible-study/hosts
touch ansible-study/web-notls.yml

创建主部署文件web-notls.yml

文件路径：./playbook/ansible-nginx

- name: Configure webserver with nginx
hosts: webservers
sudo: True
tasks:
- name: Nginx Install rpm
yum:
name: http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm 
- name: Nginx install nginx
yum:
name: nginx
state: latest
- name: copy nginx config file
copy: src=files/nginx.conf dest=/etc/nginx/sites-available/default

- name: copy index.html
template:
src: templates/index.html.j2
dest: /usr/share/nginx/html/index.html
mode: 0644

- name: restart nginx
service: name=nginx state=restarted

编辑一个nginx配置文件

运行Playbook之前，它还需要2个额外的文件，首先，需要定义个nginx的配置文件

通常来讲，Ansible会将一般文件放在名为files的子目录中，将Jinja2模版文件放在名为templates的子目录中。

文件路径：./playbook/ansible-nginx/files

server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html
index index.html index.htm;

server_name localhost;

location / {
try_files $uri $uri/ = 404;
}
}

创建一个定制的首页

添加一个定制的首页，用来测试Nginx的服务正常与否。

文件路径：./playbook/ansible-nginx/templates

<html>
<head>
<title>Welcome to ansible</title>
</head>
<body>
<h1>nginx,configured by Ansible</h1>
<p>If you can see this,Ansible successfully installed nginx.</p>
<p>{{ ansible_managed }}</p>
</body>
</html>

运行playbook，部署nginx

执行playbook需要使用ansible-playbook命令，按照如下方法运行playbook

LS-MacBook-Pro:ansible-study wangzhen$ ansible-playbook web-notls.yml
[DEPRECATION WARNING]: Instead of sudo/sudo_user, use become/become_user and make sure become_method is 'sudo' (default).
This feature will be removed in a
future release. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
