使用windos电脑模拟搭建集群(四)web环境 linux+nginx+jdk+tomcat

1.使用ansible的playbook自动安装两台web主机的nginx

1.配置模块 主机清单

2.创建 playbook目录并编写安装nginx的playbook

mkdir -p playbookDir/ansible-nginx

[root@mage-monitor- ansible-nginx]# cat install_nginx.yml
- hosts: web
  tasks:
    - name: NGINX | Installing NGINX repo rpm
      yum:
       name: http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
    - name: NGINX | Installing NGINX
      yum:
        name: nginx
        state: latest
    - name: NGINX | Starting NGINX
      service:
        name: nginx
        state: started

3.执行playbook

4.查看nginx服务

5.将nginx设置成开启启动项

2.使用playbook自动安装java环境

1.创建java的playbook目录并编写playbook

[root@mage-monitor- playbookDir]# mkdir ansible-java

2.编写设置远端主机的jdk环境变量配置脚本 set_jdk.sh

#!/bin/bash

echo "export JAVA_HOME=${HOME}/jdk" >> ~/.bash_profile
echo 'export CLASSPATH=.:${JAVA_HOME}/lib' >> ~/.bash_profile
echo 'export PATH=${JAVA_HOME}/bin:$PATH' >> ~/.bash_profile
source ~/.bash_profile

3.编写 安装java 环境的 playbook

---
- hosts: web
  tasks:
    - name: .copy jdk to remote host
      copy: src=jdk-8u161-linux-x64.tar.gz dest=~
    - name: .tar jdk
      shell: tar zxf jdk-8u161-linux-x64.tar.gz
    - name: .create soft link
      shell: ln -s ~/jdk1..0_161 jdk
    - name: .copy script to remote
      copy: src=set_jdk.sh dest=~
    - name: .execute script
      shell: /bin/bash set_jdk.sh
    - name: .copy tomcat to remote host
      copy: src=apache-tomcat-8.0..tar.gz dest=~
    - name: .tar  tomcat
      shell: tar zxf apache-tomcat-8.0..tar.gz
    - name: .start tomcat
      shell: /apache-tomcat-8.0./bin/startup.sh 

4.执行playbook

[root@mage-monitor- ansible-java]# ansible-playbook intall-java.yml  

5.检查tomcat进程，如果存在进程，标识jdk环境变量没问题和tomcat也安装成功了，如果环境变量配置不成功，tomcat压根无法启动。

5.页面测试一下
