ansible批量部署tomcat

1.1 构建目录结构

此操作是安装nginx+mysql+tomcat+db的目录结构，可以参考一下，不错~
mkdir -p /ansible/roles/{nginx,mysql,tomcat,db}/{defaults,files,handlers,meta,tasks,templates,vars}

• defaults 默认寻找路径
• tasks 存放playbooks路径
• files 存放文件和脚本包，copy模块文件搜索路径
• templates 模版存放路径
• handlers notify调用部分playbook存放路径
• vars roles内变量存放路径

1.2 文件目录结构

[root@qtbackup ~]# tree /ansible/
/ansible/
├── playbook
│   └── playbook.yml
├── roles
│   ├── db
│   │   ├── defaults
│   │   ├── files
│   │   ├── handlers
│   │   ├── meta
│   │   ├── tasks
│   │   ├── templates
│   │   └── vars
│   ├── mysql
│   │   ├── defaults
│   │   ├── files
│   │   ├── handlers
│   │   ├── meta
│   │   ├── tasks
│   │   ├── templates
│   │   └── vars
│   ├── nginx
│   │   ├── defaults
│   │   ├── files
│   │   ├── handlers
│   │   ├── meta
│   │   ├── tasks
│   │   ├── templates
│   │   └── vars
│   └── tomcat
│       ├── defaults
│       ├── files
│       │   ├── apache-tomcat-8.0.29.tar.gz
│       │   ├── jdk-8u73-linux-x64.gz
│       │   ├── tomcat-initscript.sh
│       │   └── tomcat-users.xml
│       ├── handlers
│       │   └── main.yml
│       ├── meta
│       ├── tasks
│       │   └── main.yml
│       ├── templates
│       │   └── tomcat-users.xml
│       └── vars
├── ssh_key.sh       ###自动分发sshkey脚本 （下边会完整贴出来）
├── web.retry
└── web.yml          ####总调用文件

34 directories, 11 files
[root@qtbackup ~]#

1.3 在ansible目录创建一个总调用文件

- hosts: bgo   ####这个是hosts定义个主机组名字，如果是单台主机可以直接写地址
  remote_user: root          ####执行用户
  roles:                     #####解释配置文件目录，因为我们这次装的是tomcat所以注释其他的
 #   - nginx
 #   - mysql
    - tomcat
 #   - db

1.4 创建tomcat安装playbook文件

vim   /ansible/roles/tomcat/tasks/main.yml

#这个是用yum模块安装jdk，有需要的可以用
#- name: install java
#  yum: name=java-1.8.0-openjdk.x86_64   state=present

===============================================================
#创建用户
- name: group
  group: name=tomcat
- name: user
  user: name=tomcat group=tomcat home=/usr/tomcat
  sudo: True

##############################这个源码包安装JDK#############################
#复制jdk到tmp目录下
- name: copy jdk-8u73-linux-x64.gz
  copy: src=jdk-8u73-linux-x64.gz dest=/tmp/jdk-8u73-linux-x64.gz
#解压jdk包到/application
- name: Extract archive jdk
  command: /bin/tar xf /tmp/jdk-8u73-linux-x64.gz -C /application
#改名
- name: java
  shell: mv /application/jdk1.8.0_73 /application/java
#添加环境变量
- name: add /etc/profile
  lineinfile: dest=/etc/profile regexp="^JAVA_HOME=" line="JAVA_HOME=/application/java/"
- name: add /etc/profile
  lineinfile: dest=/etc/profile regexp="^CLASS_PATH=" line="CLASS_PATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib"
- name: add /etc/profile
  lineinfile: dest=/etc/profile regexp="^PATH=$PATH:$JAVA_HOME" line="PATH=$PATH:$JAVA_HOME/bin"
- name: add /etc/profile
  lineinfile : dest=/etc/profile regexp="^export JAVA_HOME" line="export JAVA_HOME"

##########################安装tomcat###########################################
- name: copy tomcat_tar_gz
  copy: src=apache-tomcat-8.0.29.tar.gz dest=/tmp/apache-tomcat-8.0.29.tar.gz
#解压tomcat到opt目录
- name: Extract archive
  command: /bin/tar xf /tmp/apache-tomcat-8.0.29.tar.gz -C /opt
#创建软连接
- name: Symlink install directory
  file: src=/opt/apache-tomcat-8.0.29/ dest=/application/tomcat state=link
#赋予目录权限
- name: Change ownership of Tomcat installation
  file: path=/application/tomcat/ owner=tomcat group=tomcat state=directory recurse=yes
#推送配置文件
- name: Configure Tomcat users
  template: src=tomcat-users.xml dest=/application/tomcat/conf/
  notify: restart tomcat
#安装tomcat。init启动脚本
- name: Install Tomcat init script
  copy: src=tomcat-initscript.sh dest=/etc/init.d/tomcat mode=0755
#开启tomcat
- name: Start Tomcat
  service: name=tomcat state=started enabled=yes

1.5 通过notify调用handlers

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

1.6 语法检测===执行安装

cd /ansible
ansible-playbook web.yml --syntax-check  #检查语法
ansible-playbook web.yml  #执行
