3 playbook使用实例

一 playbook安装nginx

1.1 前期准备

/home/yx/nginx_install/files/nginx-1.12.2.tar.gz  #nginx安装包
/home/yx/nginx_install/templates/install_nginx.sh # nginx安装脚本
/home/yx/nginx_install/templates/nginx.conf # nginx配置文件
/home/yx/nginx_install/templates/index.html # 首页展示

/home/yx/nginx_install/templates/index.php # php首页展示


ansible 192.168.6.220 -m copy -a "src=/home/yx/nginx_install dest=/home/yx/ mode=0755"  # 然后批量拷贝文件到指定主机

1.2 编译安装nginx

- hosts: 192.168.6.220
  remote_user: root
  vars:
  - nginx_version: 1.12.2
  - nginx_web_dir: /home/yx/server/nginx
  - nginx_user: yx
  tasks:
  - name: 拷贝nginx软件包
    copy: src=/home/yx/nginx_install/files/nginx-1.12.2.tar.gz  dest=/tmp/nginx-1.12.2.tar.gz owner=yx group=yx
  - name: 解压
    shell: tar -zxf /tmp/nginx-{{ nginx_version }}.tar.gz -C /tmp
  - name: 开始编译并安装
    shell: cd /tmp/nginx-1.12.2/ && bash /home/yx/nginx_install/templates/install_nginx.sh
  - name: 创建logs和vhost目录
    file: path={{ nginx_web_dir }}/{{item}}  state=directory
    with_items:
      - vhost
      - logs
  - name: 更改新创建目录的属主为yx
    shell: sudo chown -R yx:yx {{ nginx_web_dir }}
  - name: 删除解压完的nginx目录
    shell: rm -rf /tmp/nginx-{{ nginx_version }}

  - name: 拷贝指定nginx配置文件 
    template: src=/home/yx/nginx_install/templates/nginx.conf dest=/home/yx/server/nginx/config/ owner=yx group=yx mode=0644
  - name: 拷贝测试主机文件
    template: src=/home/yx/nginx_install/templates/vhost.conf dest=/home/yx/server/nginx/config/vhost/ owner=yx group=yx mode=0644
  - name: 设置指定的首页展示html
    template: src=/home/yx/nginx_install/templates/index.html dest={{ nginx_web_dir }}/vhost/index.html owner={{ nginx_user }} group={{ nginx_user }} mode=0644
  - name: 设置指定的首页展示php
    template: src=/home/yx/nginx_install/templates/index.php dest={{ nginx_web_dir }}/vhost/ owner={{ nginx_user }} group={{ nginx_user }} mode=0644
  #handlers:
  - name: 启动nginx服务
    shell: sudo /home/yx/server/nginx/sbin/nginx


# vars指定参数   with_items:是循环创建目录

然后执行 ansible-playbook install_nginx.yaml -s -K
解释
-s 使用sudo
-K 提示密码使用sudo，sudo表示提权操作

二 playbook安装mysql

2.1 编译安装mysql

前期说明文件存放位置

# 存放mysql安装包
ls files/
mysql-boost-5.7.19.tar.gz
#####配置文件和脚本
ls templates/
install_mysql.sh  my.cnf  mysqld

ploybook文件

- hosts: 192.168.10.227
  remote_user: root
  vars:
  - mysql_version: 5.7.19
  - mysql_dir: /home/yx/server/mysql
  - mysql_user: yx
  - ip: 192.168.6.220
  tasks:
  - name: 安装依赖环境
    shell: sudo yum install -y ncurses-devel cmake
  - name: 创建mysql各自目录
    shell: mkdir -p {/home/yx/server/mysql/tmp,/home/yx/server/mysql/mysqldata,/home/yx/server/mysql/etc,/home/yx/server/mysql/mysqllog/binlog}
  - name: 拷贝文件
    copy: src=/home/yx/mysql_install/files/mysql-boost-5.7.19.tar.gz  dest=/tmp/ owner=yx group=yx
  - name: 解压
    shell: tar -zxf /tmp/mysql-boost-{{ mysql_version }}.tar.gz -C /tmp
  - name: 开始编译并安装
    shell: cd /tmp/mysql-{{ mysql_version }}/ && bash /home/yx/mysql_install/templates/install_mysql.sh
  - name: 更改新创建目录的属主为yx
    shell: sudo chown -R yx:yx {{ mysql_dir }}
  - name: 删除解压完的mysql目录
    shell: rm -rf /tmp/mysql-{{ mysql_version }}
  - name: 初始化数据库
    shell: /home/yx/server/mysql/bin/mysqld --initialize-insecure --user=yx --basedir=/home/yx/server/mysql --datadir=/home/yx/server/mysql/mysqldata

  - name: 拷贝指定mysql配置文件 
    template: src=/home/yx/mysql_install/templates/my.cnf dest=/home/yx/server/mysql/etc/ owner=yx group=yx mode=0644
  - name: 拷贝mysql启动脚本
    template: src=/home/yx/mysql_install/templates/mysqld dest=/etc/init.d/
  - name: 添加权限
    shell: sudo chmod +x /etc/init.d/mysqld
  - name: 启动mysql
    shell: /etc/init.d/mysqld start

执行 ansible-playbook install_mysql.yaml
