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-01 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-01 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/bashecho "export JAVA_HOME=${HOME}/jdk" >> ~/.bash_profileecho 'export CLASSPATH=.:${JAVA_HOME}/lib' >> ~/.bash_profileecho 'export PATH=${JAVA_HOME}/bin:$PATH' >> ~/.bash_profilesource ~/.bash_profile

 

 

3.编写 安装java 环境的 playbook

---- hosts: web   tasks:    - name: 1.copy jdk to remote host      copy: src=jdk-8u161-linux-x64.tar.gz dest=~    - name: 2.tar jdk       shell: tar zxf jdk-8u161-linux-x64.tar.gz    - name: 3.create soft link      shell: ln -s ~/jdk1.8.0_161 jdk     - name: 4.copy script to remote      copy: src=set_jdk.sh dest=~    - name: 5.execute script      shell: /bin/bash set_jdk.sh    - name: 6.copy tomcat to remote host      copy: src=apache-tomcat-8.0.50.tar.gz dest=~    - name: 7.tar  tomcat      shell: tar zxf apache-tomcat-8.0.50.tar.gz    - name: 8.start tomcat      shell: /apache-tomcat-8.0.50/bin/startup.sh

4.执行playbook

[root@mage-monitor-01 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
