使用Ansible-playbook部署Nginx+Tomcat

准备环境

测试服务器4台

192.168.14.10 操作机

192.168.14.20 主机

192.168.14.30 主机

192.168.14.40 主机

操作机

1. 安装epel源

yum -y install epel-release

2. 通过epel安装Ansible

yum -y install ansible

3. 配置主机群组

vim /etc/ansible/hosts
#在文件最后添加
[webs]
192.168.14.10  把操作机也添加
192.168.14.20
192.168.14.30
192.168.14.40

4. 使用ssh连接主机群组

#一路回车
ssh-keygen
Enter file in which to save the key (/root/.ssh/id_rsa):
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:F5ZCtmMkn3+04fsT2n+yRY/WNW3pFREYc7j1qSTg14I root@localhost.localdomain
The key's randomart image is:

#输入root密码
[root@localhost ~]# ssh-copy-id 192.168.14.10 
[root@localhost ~]# ssh-copy-id 192.168.14.20
[root@localhost ~]# ssh-copy-id 192.168.14.30
[root@localhost ~]# ssh-copy-id 192.168.14.40

5. 测试是否连接主机群组

ansible webs -m ping
192.168.14.10 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
192.168.14.30 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
192.168.14.40 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
192.168.14.20 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}

6. 使用playbook一键部署

cd /etc/ansible
vim nginx.yml

7. yml文件

---
- hosts: webs
  tasks:
    - name: "安装组件"
      yum: name={{ item }} state=latest
      with_items:
        - openssl-devel
        - zlib-devel
        - pcre-devel
        - gcc
        - gcc-c++
    - name: "解压源码包"
      unarchive: src=nginx-1.4.7.tar.gz dest=/root
    - name: "编译"
      shell: chdir=/root/nginx-1.4.7 ./configure && make && make install
    - name: "分发配置文件"
      copy: src=nginx.conf dest=/usr/local/nginx/conf/nginx.conf
    - name: "启动nginx"
      shell: /usr/local/nginx/sbin/nginx
    - name: "安装djk环境"
      yum: name=java-1.8.0-openjdk state=latest
    - name: "创建tomcat目录"
      shell: mkdir /opt/tomcat
    - name: "解压tomcat源码包"
      unarchive: src=apache-tomcat-7.0.47.tar.gz dest=/opt/tomcat
    - name: "启动tomcat"
      shell: nohup /opt/tomcat/apache-tomcat-7.0.47/bin/startup.sh &

8. nginx配置文件

 location / {
            root   html;
            index  index.html index.htm index.jsp;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        location ~ \.jsp$ {
            proxy_pass   http://127.0.0.1:8080;
        }

完成
