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