1. ansible-初始playbook安装nginx
1) 创建一个ansible存放路径
1 [root@test-1 scripts]# mkdir -p /ansible/nginx/{conf,bin}
2) 验证存放路径
1 [root@test-1 bin]# tree /ansible/ 2 /ansible/ 3 └── nginx 4 ├── bin 5 │ └── nginx.yaml 6 └── conf 7 └── site.conf 8 9 3 directories, 2 files
2. 编写playbook的nginx安装yaml文件
1) 编写nginx.yaml配置文件
1 [root@test-1 bin]# vim /ansible/nginx/bin/nginx.yaml 2 [root@test-1 bin]#cat /ansible/nginx/bin/nginx.yaml 3 - hosts: web1 4 remote_user: root 5 vars: 6 hello: Ansible 7 8 tasks: 9 - name: Add repo 10 yum_repository: 11 name: nginx 12 description: nginx repo 13 baseurl: http://nginx.org/packages/centos/7/$basearch/ 14 gpgcheck: no 15 enabled: 1 16 - name: Install nginx 17 yum: 18 name: nginx 19 state: latest 20 - name: Copy nginx configuration file 21 copy: 22 src: /ansible/nginx/conf/site.conf 23 dest: /etc/nginx/conf.d/site.conf 24 - name: Start nginx 25 service: 26 name: nginx 27 state: started 28 - name: Create wwwroot directory 29 file: 30 dest: /var/www/html 31 state: directory 32 - name: Create test page index.html 33 shell: echo "hello {{hello}}" > /var/www/html/index.html
2) 编写nginx的配置文件
1 [root@test-1 bin]# vim /ansible/nginx/conf/site.conf 2 [root@test-1 bin]# cat /ansible/nginx/conf/site.conf 3 server { 4 listen 80; 5 server_name www.ctnrs.com; 6 location / { 7 root /var/www/html; 8 index index.html; 9 } 10 }
3. 验证playbook是否正确
1) 验证
1 [root@test-1 bin]# ansible-playbook /ansible/nginx/bin/nginx.yaml --syntax-check 2 [WARNING]: log file at /var/log/ansible/ansible.log is not writeable and we cannot create it, aborting 3 4 5 playbook: /ansible/nginx/bin/nginx.yaml
提示：
验证配置文件正确，没问题
4. 执行ansible-playbook远程安装
1) 执行安装nginx
1 [root@test-1 bin]# ansible-playbook /ansible/nginx/bin/nginx.yaml 2 3 PLAY [web1] ****************************************************************************************************************************************************************************************************************************************************************** 4 5 TASK [Gathering Facts] ******************************************************************************************************************************************************************************************************************************************************* 6 ok: [192.168.200.132] 7 ok: [192.168.200.133] 8 9 TASK [Add repo] ************************************************************************************************************************************************************************************************************************************************************** 10 ok: [192.168.200.132] 11 ok: [192.168.200.133] 12 13 TASK [Install nginx] ********************************************************************************************************************************************************************************************************************************************************* 14 changed: [192.168.200.132] 15 changed: [192.168.200.133] 16 17 TASK [Copy nginx configuration file] ***************************************************************************************************************************************************************************************************************************************** 18 ok: [192.168.200.132] 19 ok: [192.168.200.133] 20 21 TASK [Start nginx] *********************************************************************************************************************************************************************************************************************************************************** 22 changed: [192.168.200.133] 23 changed: [192.168.200.132] 24 25 TASK [Create wwwroot directory] ********************************************************************************************************************************************************************************************************************************************** 26 ok: [192.168.200.132] 27 ok: [192.168.200.133] 28 29 TASK [Create test page index.html] ******************************************************************************************************************************************************************************************************************************************* 30 changed: [192.168.200.133] 31 changed: [192.168.200.132] 32 33 PLAY RECAP ******************************************************************************************************************************************************************************************************************************************************************* 34 192.168.200.132 : ok=7 changed=3 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 35 192.168.200.133 : ok=7 changed=3 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
5. 验证是否部署成功
1) 验证
1 [root@test-1 bin]# ansible web1 -m shell -a "ps -ef |grep nginx" 2 [WARNING]: log file at /var/log/ansible/ansible.log is not writeable and we cannot create it, aborting 3 4 192.168.200.132 | CHANGED | rc=0 >> 5 root 17792 1 0 15:04 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf 6 nginx 17793 17792 0 15:04 ? 00:00:00 nginx: worker process 7 root 17970 17965 68 15:22 pts/1 00:00:00 /bin/sh -c ps -ef |grep nginx 8 root 17972 17970 0 15:22 pts/1 00:00:00 grep nginx 9 10 192.168.200.133 | CHANGED | rc=0 >> 11 root 17881 1 0 15:04 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf 12 nginx 17882 17881 0 15:04 ? 00:00:00 nginx: worker process 13 root 18058 18053 73 15:22 pts/1 00:00:00 /bin/sh -c ps -ef |grep nginx 14 root 18060 18058 0 15:22 pts/1 00:00:00 grep nginx 15 16 17 [root@test-1 bin]# ansible web1 -m shell -a "netstat -lntup |grep 80" 18 [WARNING]: log file at /var/log/ansible/ansible.log is not writeable and we cannot create it, aborting 19 20 192.168.200.132 | CHANGED | rc=0 >> 21 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 17792/nginx: master 22 23 192.168.200.133 | CHANGED | rc=0 >> 24 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 17881/nginx: master
2) 模拟浏览器请求
1 [root@test-1 scripts]# curl 192.168.200.132 -H "Host:www.ctnrs.com" 2 hello Ansible 3 [root@test-1 scripts]# curl 192.168.200.133 -H "Host:www.ctnrs.com" 4 hello Ansible
