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
安装mysql脚本
