main vars onf xtra sta ans playbooks == enabled
1.1 構建目錄結構
此操作是安裝nginx+mysql+tomcat+db的目錄結構，可以參考一下，不錯~
mkdir -p /ansible/roles/{nginx,mysql,tomcat,db}/{defaults,files,handlers,meta,tasks,templates,vars}
- defaults 默認尋找路徑
- tasks 存放playbooks路徑
- files 存放文件和腳本包，copy模塊文件搜索路徑
- templates 模版存放路徑
- handlers notify調用部分playbook存放路徑
- vars roles內變量存放路徑
1.2 文件目錄結構
[[email protected] ~]# 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 ###自動分發sshkey腳本 （下邊會完整貼出來） ├── web.retry └── web.yml ####總調用文件34 directories, 11 files [[email protected] ~]#
1.3 在ansible目錄創建一個總調用文件
- hosts: bgo ####這個是hosts定義個主機組名字，如果是單臺主機可以直接寫地址 remote_user: root ####執行用戶 roles: #####解釋配置文件目錄，因為我們這次裝的是tomcat所以註釋其他的 # - nginx # - mysql - tomcat # - db
1.4 創建tomcat安裝playbook文件
vim /ansible/roles/tomcat/tasks/main.yml #這個是用yum模塊安裝jdk，有需要的可以用 #- name: install java # yum: name=java-1.8.0-openjdk.x86_64 state=present =============================================================== #創建用戶 - name: group group: name=tomcat - name: user user: name=tomcat group=tomcat home=/usr/tomcat sudo: True ##############################這個源碼包安裝JDK############################# #復制jdk到tmp目錄下 - name: copy jdk-8u73-linux-x64.gz copy: src=jdk-8u73-linux-x64.gz dest=/tmp/jdk-8u73-linux-x64.gz #解壓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 #添加環境變量 - 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" ##########################安裝tomcat########################################### - name: copy tomcat_tar_gz copy: src=apache-tomcat-8.0.29.tar.gz dest=/tmp/apache-tomcat-8.0.29.tar.gz #解壓tomcat到opt目錄 - name: Extract archive command: /bin/tar xf /tmp/apache-tomcat-8.0.29.tar.gz -C /opt #創建軟連接 - name: Symlink install directory file: src=/opt/apache-tomcat-8.0.29/ dest=/application/tomcat state=link #賦予目錄權限 - 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 #安裝tomcat。init啟動腳本 - name: Install Tomcat init script copy: src=tomcat-initscript.sh dest=/etc/init.d/tomcat mode=0755 #開啟tomcat - name: Start Tomcat service: name=tomcat state=started enabled=yes
1.5 通過notify調用handlers
- name: restart tomcat
service: name=tomcat state=restarted
1.6 語法檢測===執行安裝
cd /ansible ansible-playbook web.yml --syntax-check #檢查語法 ansible-playbook web.yml #執行
