ansible部署nginx客户端
# ls tasks/main.yml

- name: sent nginx
copy: src=nginx-1.12.0.tar.gz dest=/tmp/nginx-1.12.0.tar.gz ##将安装包推送到远端，会调用files目录下的安装包。
- name: tar nginx
shell: cd /tmp;tar -xf nginx-1.12.0.tar.gz ##解压缩安装包。
- name: install packages
yum: name={{ item }} state=latest ##使用with循环安装依赖包。
with_items:
- openssl-devel
- pcre-devel
- name: install nginx
shell: cd /tmp/nginx-1.12.0;./configure --user=nginx --group=nginx --prefix=/opt/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre;make && make install ##编译安装nginx
- name: useradd nginx
shell: useradd nginx -s /sbin/nologin ##添加nginx用户。
- name: copy nginx.conf
template: src=nginx.conf dest=/opt/nginx/conf/nginx.conf ##将本地配置好的配置文件推送到远端，会调用templates目录下的文件。
tags: copynginx.conf ##打一个标签。
- name: start nginx
shell: /opt/nginx/sbin/nginx ##开启nginx服务
notify: reload nginx ##触发器，当复制过去的文件有差异时便会出发handlers模块里的文件。
nginx配置文件，里面定义了一些变量，使得可以被用来安装多台nginx。
# ls templates/
nginx.conf
# cat templates/nginx.conf

worker_processes{{ ansible_processor_vcpus }}; ###ansible带的变量，可以通过命令ansible 192.168.40.147 -m setup找到客户机相应的值。
