运维自动化之ansible playbook安装nginx
上次介绍了如何使用ansible playbook安装mysql（http://dl528888.blog.51cto.com/2382721/1437882），这次介绍一下如何使用playbook安装nginx。
下面是安装nginx的信息：
nginx_user: www nginx用户 nginx_port: 80 nginx监听端口 nginx_web_dir: /data/webroot/nginx nginx的目录 nginx_version: 1.4.3 nginx的版本 pcre_version: 8.33 pcre的版本 pretended_name: Tengine 为了安全起见，把nginx名字改为tengine pretended_version: 1.5.2 隐藏版本，换个tengine的版本
备注：此playbook仅能对centos或者redhat的6.x版本进行安装。
下面是安装nginx的playbook结构
09:33:15 # tree nginx_* nginx_delete ├── files ├── handlers ├── meta │ └── main.yml ├── tasks │ ├── delete.yml │ └── main.yml ├── templates └── vars └── main.yml nginx_install ├── files │ └── nginx-1.4.3.tar.gz ├── handlers ├── meta │ └── main.yml ├── tasks │ ├── copy.yml │ ├── delete.yml │ ├── install.yml │ └── main.yml ├── templates │ ├── index.html │ ├── index.php │ ├── install_nginx.sh │ ├── nginx │ ├── nginx.conf │ └── vhost.conf └── vars └── main.yml 12 directories, 17 files
playbook的nginx安装是
09:34:04 # cat nginx_install.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- common
- pcre_install
- nginx_install
playbook的nginx删除为
09:35:06 # cat nginx_delete.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- nginx_delete
- pcre_delete
1、安装nginx
09:26:58 # time ansible-playbook nginx_install.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem PLAY [192.168.240.17] ********************************************************* GATHERING FACTS *************************************************************** ok: [192.168.240.17] TASK: [common | Install initializtion require software] *********************** changed: [192.168.240.17] TASK: [pcre_install | Copy Pcre Software To Redhat Client] ******************** changed: [192.168.240.17] TASK: [pcre_install | Uncompression Pcre Software In Redhat Client] *********** changed: [192.168.240.17] TASK: [pcre_install | Delete Pcre Software In Redhat Client] ****************** changed: [192.168.240.17] TASK: [nginx_install | Copy Nginx Software To Redhat Client] ****************** changed: [192.168.240.17] TASK: [nginx_install | Uncompression Nginx Software To Redhat Client] ********* changed: [192.168.240.17] TASK: [nginx_install | Copy Nginx Start Script To Redhat Client] ************** changed: [192.168.240.17] TASK: [nginx_install | Copy Nginx Config To Redhat Client] ******************** changed: [192.168.240.17] TASK: [nginx_install | Copy Nginx Vhost Config to RedHat Client] ************** changed: [192.168.240.17] TASK: [nginx_install | Create Nginx User In Redhat Client] ******************** changed: [192.168.240.17] TASK: [nginx_install | Create Nginx Dir] ************************************* changed: [192.168.240.17] => (item=vhost) changed: [192.168.240.17] => (item=logs) TASK: [nginx_install | Modify Nginx Dir Permission In Redhat Client] ********** changed: [192.168.240.17] => (item=/data/webroot/nginx) changed: [192.168.240.17] => (item=/usr/local/nginx-1.4.3) TASK: [nginx_install | Create Index Html To Redhat Client] ******************** changed: [192.168.240.17] TASK: [nginx_install | Install Check Script In Redhat Client] ***************** changed: [192.168.240.17] TASK: [nginx_install | Start Nginx Service In Redhat Client] ****************** changed: [192.168.240.17] TASK: [nginx_install | Add Boot Start Nginx Service In Redhat Client] ********* changed: [192.168.240.17] TASK: [nginx_install | Delete Nginx compression Software In Redhat Client] **** changed: [192.168.240.17] PLAY RECAP ******************************************************************** 192.168.240.17 : ok=18 changed=17 unreachable=0 failed=0 real 0m53.357s user 0m2.433s sys 0m0.341s
2、安装后测试
[root@ip-10-10-240-21 local]# ps -ef|grep nginx
root 27791 1 0 21:27 ? 00:00:00 nginx: master process /usr/local/nginx-1.4.3/sbin/nginx -c /usr/local/nginx-1.4.3/conf/nginx.conf

3、删除nginx
09:28:02 # time ansible-playbook nginx_delete.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem PLAY [192.168.240.17] ********************************************************* GATHERING FACTS *************************************************************** ok: [192.168.240.17] TASK: [nginx_delete | stop nginx service] ************************************* changed: [192.168.240.17] TASK: [nginx_delete | Delete Nginx Boot Start Script] ************************* changed: [192.168.240.17] TASK: [nginx_delete | Delete Nginx Dir] *************************************** changed: [192.168.240.17] TASK: [nginx_delete | Delete Nginx User] ************************************** changed: [192.168.240.17] TASK: [nginx_delete | Delete Nginx Service Start Script] ********************** changed: [192.168.240.17] TASK: [pcre_delete | Delete Pcre] ********************************************* changed: [192.168.240.17] PLAY RECAP ******************************************************************** 192.168.240.17 : ok=7 changed=6 unreachable=0 failed=0 real 0m30.222s user 0m0.774s sys 0m0.126s
4、删除后测试
[root@ip-10-10-240-21 local]# ps -ef|grep nginx root 28417 26349 0 21:37 pts/0 00:00:00 grep nginx [root@ip-10-10-240-21 local]# chkconfig --list|grep nginx [root@ip-10-10-240-21 local]# ll /etc/init.d/nginx ls: cannot access /etc/init.d/nginx: No such file or directory [root@ip-10-10-240-21 local]# ll /usr/local/ total 44 drwxr-xr-x. 2 root root 4096 Sep 23 2011 bin drwxr-xr-x. 2 root root 4096 Sep 23 2011 etc drwxr-xr-x. 2 root root 4096 Sep 23 2011 games drwxr-xr-x. 2 root root 4096 Sep 23 2011 include drwxr-xr-x. 2 root root 4096 Jul 10 22:43 lib drwxr-xr-x. 2 root root 4096 Sep 23 2011 lib64 drwxr-xr-x. 2 root root 4096 Sep 23 2011 libexec drwxr-xr-x. 2 root root 4096 Sep 23 2011 sbin drwxr-xr-x. 5 root root 4096 May 12 2013 share drwxr-xr-x. 3 root root 4096 May 12 2013 src drwxr-xr-x 5 zabbix zabbix 4096 Jul 8 02:17 zabbix
可与看到都删除了。
如果大家想使用我的例子，可以从github里下载（地址是https://github.com/dl528888/ansible-examples/tree/master/nginx_install），然后放到/etc/ansible目录里，下面是内容
