ansible-playbook批量部署Tomcat

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

• 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
