角色	IP	主机名	软件
ansible控制	192.168.98.165	ansible1	ansible
节点1	192.168.98.166	ansible2
节点2	192.168.98.167	ansible3

一、准备 ansible 环境，安装好 ansible

1.1 安装 epel 源

dnf install https://mirrors.aliyun.com/epel/epel-release-latest-9.noarch.rpm

[root@ansible1 ~]# dnf install https://mirrors.aliyun.com/epel/epel-release-latest-9.noarch.rpm -y

[root@ansible1 ~]# ls /etc/yum.repos.d/
dnf.repo  docker-ce.repo  epel-cisco-openh264.repo  epel.repo  epel-testing.repo  redhat.repo

1.2 安装anible

dnf install ansible -y

[root@ansible1 ~]# dnf install ansible -y
Updating Subscription Management repositories.
Unable to read consumer identity

This system is not registered with an entitlement server. You can use "rhc" or "subscription-manager" to register.
.....

1.3 验证安装是否成功

ansible --version

[root@ansible1 ~]# ansible --version
ansible [core 2.14.17]
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.9/site-packages/ansible
  ansible collection location = /root/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible
  python version = 3.9.19 (main, Aug 23 2024, 00:00:00) [GCC 11.5.0 20240719 (Red Hat 11.5.0-2)] (/usr/bin/python3)
  jinja version = 3.1.2
  libyaml = True

1.4 配置目标主机，编辑映射关系

编辑 /etc/hosts 文件，把需要安装 tomcat 的服务器 IP 添加进去

[root@ansible1 ~]# vim /etc/hosts
[root@ansible1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.98.165 ansible1
192.168.98.166 ansible2
192.168.98.167 ansible3

二、使用Playbook来实现tomcat远程批量安装

2.1 创建项目目录、清单目录及文件

[root@ansible1 ~]# ls
apache-tomcat-11.0.9.tar.gz jdk-21_linux-x64_bin.tar.gz
[root@ansible1 ~]# mkdir -p remote_dnftomcat/inventory
[root@ansible1 ~]# ls
apache-tomcat-11.0.9.tar.gz jdk-21_linux-x64_bin.tar.gz  remote_dnftomcat
[root@ansible1 ~]# cd remote_dnftomcat/inventory/
[root@ansible1 inventory]# ls
[root@ansible1 inventory]# vim hosts
[root@ansible1 inventory]# cat hosts
[server]
ansible[2:3]
[root@ansible1 inventory]# ls
hosts
[root@ansible1 inventory]# cd ..
[root@ansible1 remote_dnftomcat]# tree .
.
└── inventory
    └── hosts

1 directory, 1 file

2.2 创建 ansible.cfg 配置文件

与 inventory 目录同级

[root@ansible1 remote_dnftomcat]# vim ansible.cfg
[root@ansible1 remote_dnftomcat]# cat ansible.cfg
[defaults]
inventory=inventory/hosts
[root@ansible1 remote_dnftomcat]# ls
ansible.cfg  inventory
[root@ansible1 remote_dnftomcat]# tree .
.
├── ansible.cfg
└── inventory
    └── hosts

1 directory, 2 files

2.3 创建 playbook.yaml 文件

1. 创建 下载目录（file）
2. 下载 JDK、tomcat（get_url）
3. 解压 JDK、tomcat（unarchive）[可用 unarchive 模块或者 shell 模块，使用 tar 命令]
4. 部署 JDK、tomcat

1. 下载 JDK
   进入oracle官网： oracle，复制链接，回到虚拟机 wget 下载

下载：wget https://download.oracle.com/java/21/latest/jdk-21_linux-x64_bin.tar.gz

# 下载JDK
[root@ansible1 ~]# wget https://download.oracle.com/java/21/latest/jdk-21_linux-x64_bin.tar.gz

2. 解压 JDK
   解压：tar -zxf jdk-21_linux-x64_bin.tar.gz -C /usr/local

# 解压
[root@ansible1 ~]# tar -zxf jdk-21_linux-x64_bin.tar.gz -C /usr/local

/etc/profile
vim /etc/profile 在末行添加以下内容：

3. 部署JDK

export JAVA_HOME=/usr/local/jdk-21.0.6/，export：导出JAVA的安装目录
export PATH=$PATH:$JAVA_HOME/bin，要将JAVA_HOME这个命令放到PATH中

4. 下载 tomcat
   进入tomcat官网： tomcat，复制链接，回到虚拟机wget下载

下载：wget https://dlcdn.apache.org/tomcat/tomcat-11/v11.0.9/bin/apache-tomcat-11.0.9.tar.gz
解压：tar -zxf apache-tomcat-11.0.5.tar.gz -C /usr/local/

[root@ansible1 ~]# wget https://dlcdn.apache.org/tomcat/tomcat-11/v11.0.9/bin/apache-tomcat-11.0.9.tar.gz
--2025-07-05 21:44:10--  https://dlcdn.apache.org/tomcat/tomcat-11/v11.0.9/bin/apache-tomcat-11.0.9.tar.gz

# 解压
[root@ansible1 ~]# tar -zxf apache-tomcat-11.0.9.tar.gz -C /usr/local/
[root@ansible1 ~]# ls
apache-tomcat-11.0.9.tar.gz jdk-21_linux-x64_bin.tar.gz

5. 解压 tomcat 包

6. 部署 tomcat

export TOMCAT_HOME=/usr/local/apache-tomcat-11.0.5/
export PATH=$PATH:$TOMCAT_HOME/bin

7. 刷新文件
   刷新文件让配置生效，验证 JDK 是否安装成功、tomcat 是否配置成功

source /etc/profile
java -version

8. 启动 tomcat

startup.sh

• 剧本（playbook）内容：

[root@ansible1 remote_dnftomcat]# vim playbook.yaml

2.4 执行 playbook

2.5

2.6 测试安装结果
