ansible-playbook批量部署Tomcat

偏执的太偏执、 2022-02-24 01:58 273阅读 0赞

通过ansible-playbook，批量部署tomcat。

*  将所有部署tomcat的主机分为javaserver组：

# vim /etc/ansible/hosts
    [javaserver]
    192.168.30.128
    192.168.30.129
    192.168.30.130

*  创建管理目录：

# mkdir -p tomcat/roles/tomcat_install/{files,handlers,meta,tasks,templates,vars}
    
    # cd tomcat/

说明：

files：存放需要同步到异地服务器的源码文件及配置文件； 
    handlers：当资源发生变化时需要进行的操作，若没有此目录可以不建或为空； 
    meta：存放说明信息、说明角色依赖等信息，可留空； 
    tasks：tomcat安装过程中需要进行执行的任务； 
    templates：用于执行tomcat安装的模板文件，一般为脚本； 
    vars：本次安装定义的变量

    │       └── vars
    │           └── main.yml
    └── tomcat.yml
    
    8 directories, 10 files

--------------------

*  创建tomcat入口文件，用来调用tomcat\_install：

# vim tomcat.yml 
    
    #用于批量安装Tomcat
    - hosts: javaserver
      remote_user: root
      gather_facts: True
    
      roles:
        - tomcat_install

*  创建变量：

# vim roles/tomcat_install/vars/main.yml

#定义tomcat安装中的变量
    JDK_VER: 191
    TOMCAT_VER: 8.5.39
    TOMCAT_VER_MAIN: "{ { TOMCAT_VER.split('.')[0] }}"
    DOWNLOAD_URL: https://mirrors.shu.edu.cn/apache/tomcat/tomcat-{ {  TOMCAT_VER_MAIN }}/v{ {  TOMCAT_VER }}/bin/apache-tomcat-{ {  TOMCAT_VER }}.tar.gz
    
    TOMCAT_URL: tomcat
    TOMCAT_PORT: 8080
    SOURCE_DIR: /software
    JDK_DIR: /usr/local/jdk
    TOMCAT_DIR: /usr/local/tomcat
    DATA_DIR: /data/tomcat

*  创建模板文件：

环境变量jdk\_PATH

# vim roles/tomcat_install/templates/jdk_PATH

JAVA_HOME={
       { JDK_DIR }}
    JAVA_BIN={
       { JDK_DIR }}/bin
    JRE_HOME={
       { JDK_DIR }}/jre
    PATH=$PATH:{
       { JDK_DIR }}/bin:{
       { JDK_DIR }}/jre/bin
    CLASSPATH={
       { JDK_DIR }}/jre/lib:{
       { JDK_DIR }}/lib:{
       { JDK_DIR }}/jre/lib/charsets.jar

tomcat启动脚本

# vim roles/tomcat_install/templates/tomcat

#!/bin/sh
    # chkconfig: 345 99 10
    # description: Auto-starts tomcat
    # /etc/init.d/tomcatd
    # Tomcat auto-start
    # Source function library.
    #. /etc/init.d/functions
    # source networking configuration.
    #. /etc/sysconfig/network
    prog="tomcat"
    RETVAL=0
    
    CATALINA_HOME={ {  TOMCAT_DIR }}
    
    start()
    { 
            if [ -f $CATALINA_HOME/bin/startup.sh ];
              then
                echo $"Starting $prog"
                    $CATALINA_HOME/bin/startup.sh
                RETVAL=$?
                echo " OK"
                return $RETVAL
            fi
    }
    stop()
    { 
            if [ -f $CATALINA_HOME/bin/shutdown.sh ];
              then
                echo $"Stopping $prog"
                    $CATALINA_HOME/bin/shutdown.sh
                RETVAL=$?
                #sleep 1
                ps -ef |grep $CATALINA_HOME |grep -v grep |grep -v PID | awk '{print $2}'|xargs kill -9
                echo " OK"
                # [ $RETVAL -eq 0 ] && rm -f /var/lock/...
                return $RETVAL
            fi
    }
    case "$1" in
     start)
            start
            ;;
     stop)
            stop
            ;;
     restart)
             echo $"Restaring $prog"
             $0 stop && sleep 1 && $0 start
             ;;
     *)
            echo $"Usage: $0 {start|stop|restart}"
            exit 1
            ;;
    esac
    exit $RETVAL

*  环境准备prepare.yml：

# vim roles/tomcat_install/tasks/prepare.yml

- name: 关闭firewalld 
      service: name=firewalld state=stopped enabled=no
      
    - name: 临时关闭 selinux
      shell: "setenforce 0"
      failed_when: false
    
    - name: 永久关闭 selinux
      lineinfile:
        dest: /etc/selinux/config
        regexp: "^SELINUX="
        line: "SELINUX=disabled"
    
    - name: 添加EPEL仓库
      yum: name=epel-release state=latest
    
    - name: 安装常用软件包
      yum:
        name:
          - vim
          - lrzsz
          - net-tools
          - wget
          - curl
          - bash-completion
          - rsync
          - gcc
          - unzip
          - git
        state: latest
    
    - name: 更新系统
      shell: "yum update -y"
      args:
        warn: False

*  文件拷贝copy.yml：

# vim roles/tomcat_install/tasks/copy.yml

- name: 创建software目录
      file: name={ {  SOURCE_DIR }} state=directory mode=0755 recurse=yes
    
    #本地files目录下要准备好jdk包
    - name: 拷贝jdk包
      copy: src=jdk-8u{ {  JDK_VER }}-linux-x64.tar.gz dest={ {  SOURCE_DIR }} owner=root group=root
    
    - name: 解压jdk包
      unarchive: src={ {  SOURCE_DIR }}/jdk-8u{ {  JDK_VER }}-linux-x64.tar.gz dest={ {  SOURCE_DIR }} owner=root group=root
    
    - name: 目录重命名
      shell: "if [ ! -d { { JDK_DIR }} ]; then mv { { SOURCE_DIR }}/jdk1.8.0_{ { JDK_VER }}/ { { JDK_DIR }}; fi"
    
    - name: 拷贝环境变量jdk_PATH
      template: src=jdk_PATH dest={ {  SOURCE_DIR }} owner=root group=root
    
    - name: 加入环境变量jdk_PATH
      shell: "if [ `grep { { JDK_DIR }}/bin /etc/profile |wc -l` -eq 0 ]; then cat { { SOURCE_DIR }}/jdk_PATH >> /etc/profile && source /etc/profile; fi"

*  下载安装install.yml：

# vim roles/tomcat_install/tasks/install.yml

#当前主机下没有tomcat包
    - name: 下载tomcat包
      get_url: url={ {  DOWNLOAD_URL }} dest={ {  SOURCE_DIR }} owner=root group=root
    
    #当前主机files目录下已有tomcat包
    #- name: 拷贝现有tomcat包到所有主机
    # copy: src=apache-tomcat-{ { TOMCAT_VER }}.tar.gz dest={ { SOURCE_DIR }}
    
    - name: 解压tomcat包
      unarchive: src={ {  SOURCE_DIR }}/apache-tomcat-{ {  TOMCAT_VER }}.tar.gz dest={ {  SOURCE_DIR }} owner=root group=root
    
    - name: 目录重命名
      shell: "if [ ! -d { { TOMCAT_DIR }} ]; then mv { { SOURCE_DIR }}/apache-tomcat-{ { TOMCAT_VER }}/ { { TOMCAT_DIR }}; fi"
    
    - name: 加入环境变量_1
      lineinfile:
        dest: "{ { TOMCAT_DIR }}/bin/catalina.sh"
        insertbefore: "cygwin=false"
        line: "CATALINA_HOME={ { TOMCAT_DIR }}"
    
    - name: 加入环境变量_2
      lineinfile:
        dest: "{ { TOMCAT_DIR }}/bin/catalina.sh"
        insertbefore: "cygwin=false"
        line: "JAVA_HOME={ { JDK_DIR }}"
    
    - name: 加入环境变量_3
      lineinfile:
        dest: "{ { TOMCAT_DIR }}/bin/catalina.sh"
        insertbefore: "cygwin=false"
        line: "JRE_BIN={ { JDK_DIR }}/bin"
    
    - name: 加入环境变量_4
      lineinfile:
        dest: "{ { TOMCAT_DIR }}/bin/catalina.sh"
        insertbefore: "cygwin=false"
        line: "JRE_HOME={ { JDK_DIR }}/jre"
    
    - name: 加入环境变量_5
      lineinfile:
        dest: "{ { TOMCAT_DIR }}/bin/catalina.sh"
        insertbefore: "cygwin=false"
        line: "CLASSPATH={ { JDK_DIR }}/jre/lib:{ { JDK_DIR }}/lib:{ { JDK_DIR }}/jre/lib/charsets.jar"
    
    - name: 拷贝tomcat启动脚本_1
      template: src=tomcat dest=/usr/bin/ owner=root group=root mode=0755
    
    - name: 拷贝tomcat启动脚本_2
      template: src=tomcat dest=/etc/init.d/ owner=root group=root mode=0755
    
    - name: 启动tomcat并开机启动
      service:
        name: tomcat
        state: restarted
        enabled: yes

*  引用文件main.yml：

# vim roles/tomcat_install/tasks/main.yml
    
    #引用prepare、copy、install模块
    - include: prepare.yml
    - include: copy.yml
    - include: install.yml

*  执行安装：

# ansible-playbook tomcat.yml

# netstat -lntp |grep java
    tcp6       0      0 :::8009                 :::*                    LISTEN      41113/java          
    tcp6       0      0 :::8080                 :::*                    LISTEN      41113/java          
    tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      41113/java

# chkconfig --list |grep tomcat
    
    tomcat         	0:off	1:off	2:on	3:on	4:on	5:on	6:off

tomcat安装目录是`/usr/local/tomcat`，日志目录是`/usr/local/tomcat/logs`。

测试安装没有问题，jdk包无法直接通过地址下载，需要先下载好，放到files目录下；如果本地没有下载好的tomcat包，安装会慢一点。已存放至个人gitgub：[ansible-playbook][]
