Ansible使用playbook批量安装Java

Posted 2022-04-22 SoloGuy

1.首先在ansible主机上看一下目录结构：（示例选择jdk8u221的源码包，其他版本可以自行替换）

2.hosts配置如下：（本次示例只演示1台机器）

install.yml内容如下：

- hosts: mysql
  tasks:
    - name: 拷贝安装包和脚本
      copy: 
        src: "item.src"
        dest: /root
        owner: root
        group: root
        mode: 755
      with_items: 
        - src: "jdk-8u221-linux-x64.tar.gz"
        - src: "java-install.sh"
    - name: 执行安装
      shell: cd /root && sh java-install.sh jdk-8u221-linux-x64.tar.gz

java-install.sh内容如下：

#!/bin/bash
#调用函数库
[ -f /etc/init.d/functions ] && source /etc/init.d/functions
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
source /etc/profile

#Require root to run this script.
[ $(id -u) -gt 0 ] && echo "请用root用户执行此脚本！" && exit 1

if [ $# != 1 ]; then
   echo "Usage: java-install.sh jdk*.tgz"
   exit 1
fi

echo "Unarchiving jdk..."
tar -xzf $1 -C /usr/local/
mv /usr/local/jdk* /usr/local/jdk

echo "make /etc/profile..."
cat >> /etc/profile << EOF
export JAVA_HOME=/usr/local/jdk
export JRE_HOME=/usr/local/jdk/jre
export CLASSPATH=.:/usr/local/jdk/lib:/usr/local/jdk/lib
export PATH=/usr/local/jdk/bin:$PATH
EOF
cat >> ~/.bashrc << EOF
export JAVA_HOME=/usr/local/jdk
export JRE_HOME=/usr/local/jdk/jre
export CLASSPATH=.:/usr/local/jdk/lib:/usr/local/jdk/lib
export PATH=/usr/local/jdk/bin:$PATH
EOF

source /etc/profile
source ~/.bashrc

java -version
if [ $? == 0 ];then
   echo "java安装完成"
fi

3.部署阶段：

验证机器连通性：

检查语法：

执行安装：

安装完成检查：
