1. 部署ansible
通过 ansible playbook 实现以上服务 的安装与配置
1）安装部署 ansible
[root@localhost ~]# yum -y install epel-release # 安装系统扩展源
[root@localhost ~]# yum makecache fast # 新建缓存
[root@localhost ~]# yum -y install ansible # 安装ansible
·
2） 部署 SSH 免密登陆
[root@localhost ~]# ssh-keygen
[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
3) 编辑 hosts 清单
[root@localhost ~]# vim /etc/ansible/hosts
[tomcatservers]
192.168.116.103
192.168.116.104
[tomcat-1]
192.168.116.103
[tomcat-2]
192.168.116.104
[nginxservers]
192.168.116.105
192.168.116.106
[keepalived-m]
192.168.116.105
[keepalived-s]
192.168.116.106
4） 编写Tomcat playbook

file: path=/usr/local/maven/conf/settings.xml state=absent
- name: aliyun
copy: src=/root/settings.xml dest=/usr/local/maven/conf/
- name: create webapp
shell: mvn archetype:generate -DgroupId=cn.kgc.kgcweb -DartifactId=kgcweb -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
args:
chdir: /root
- name: mvn package
shell: mvn package
args:
chdir: /root/kgcweb
- name: copy kgcwev.war
copy: src=/root/kgcweb/target/kgcweb.war dest=/usr/local/tomcat/webapps/ remote_src=yes
- name: copy sh
copy: src=/root/tomcat_start.sh dest=/root/
- name: start tomcat
shell: sh /root/tomcat_start.sh

- name: update nginx.conf
lineinfile: "path=/usr/local/nginx/conf/nginx.conf insertafter='^ location / {$' line=' proxy_pass http://www.tomcat.servers/kgcweb/index.jsp;'"
- name: start nginx
shell: nginx
6） 部署 Keeplived

<html>
<body>
<h2>Hello World!</h2>
This is Tomcaat server
