ansible- 安装nginx

zhaolu

　　实际应用- 安装nginx
　　cd  /etc/ansible
　　mkdir nginx_install
　　mkdir  -p nginx_install/roles/{common,delete,install}/{handlers,files,meta,tasks,templates,vars}
　　说明：roles目录下有三个角色，common为一些准备操作，delete为删除nginx的操作，install为安装nginx的操作
　　每个角色下面又有几个目录，handlers下面是当发生改变时要执行的操作，通常用在配置文件发生改变，重启服务。files为安装时用到的一些文件，meta为说明信息，说明角色依赖等信息，tasks里面是核心的配置文件，templates通常存一些配置文件，启动脚本等模板文件，vars下为定义的变量
　　cd  nginx_install/roles
　　vim  ./common/tasks/main.yml //内容如下
　　- name: Install initializtion require software
　　yum: name=` item ` state=installed
　　with_items:
　　- gcc
　　- zlib-devel
　　- pcre-devel
　　vim  ./install/vars/main.yml
　　nginx_user: www
　　nginx_port: 80
　　nginx_web_dir: /data/www
　　nginx_version: 1.4.3
　　ls ./install/files/
　　nginx-1.4.3.tar.gz
　　说明： 我们需要把源码包放到 files目录里面
　　ls ./install/templates
　　index.html index.php install_nginx.sh nginx nginx.conf vhost.conf
　　说明： 需要再templates下面准备好 默认页、安装nginx的shell脚本、nginx启动脚本、nginx配置文件以及虚拟主机配置文件

　　vim ./install/tasks/copy.yml
　　- name: Copy Nginx Software To Redhat Client
　　copy: src=nginx-` nginx_version `.tar.gz dest=/tmp/nginx-` nginx_version `.tar.gz owner=root group=root
　　when: ansible_os_family == "RedHat" and ansible_distribution_version|int >=6
　　- name: Uncompression Nginx Software To Redhat Client
　　shell: tar zxf /tmp/nginx-` nginx_version `.tar.gz -C /usr/local/
　　when: ansible_os_family == "RedHat" and ansible_distribution_version|int >=6
　　- name: Copy Nginx Start Script To Redhat Client
　　template: src=nginx dest=/etc/init.d/nginx owner=root group=root mode=0755
　　when: ansible_os_family == "RedHat" and ansible_distribution_version|int >=6
　　- name: Copy Nginx Config To Redhat Client
　　template: src=nginx.conf dest=/usr/local/nginx-` nginx_version `/conf/ owner=root group=root mode=0644

　　- name: Copy Nginx Vhost Config to RedHat Client

　　when: ansible_os_family == "RedHat" and ansible_distribution_version|int >=6
　　说明： 首先把压缩包拷贝到/tmp/目录下，然后解压到/usr/local/下，再拷贝启动脚本到/etc/init.d/下，再拷贝nginx.conf以及vhost.conf
