现在介绍如何使用ansible安装node。
下面是安装node的信息：
node_dir: /data node_version: 0.10.21 node_port: 3301
可以看到node的版本是0.10.21，测试的node应用服务监听3301端口
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node的playbook结构
09:33:16 # tree node_* node_delete ├── files ├── handlers ├── meta │ └── main.yml ├── tasks │ ├── delete.yml │ └── main.yml ├── templates └── vars └── main.yml node_install ├── files │ └── node-0.10.21.tar.gz ├── handlers ├── meta │ └── main.yml ├── tasks │ ├── copy.yml │ ├── delete.yml │ └── main.yml ├── templates │ └── app.js └── vars └── main.yml 12 directories, 11 files
playbook安装node的是
09:32:54 # cat node_install.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- common
- node_installplaybook删除node的是
09:34:18 # cat node_delete.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- node_delete下面是安装与测试过程
1、安装node环境
09:42:34 # time ansible-playbook node_install.yml --extra-vars "host=172.17.0.3 user=root" -k SSH password: PLAY [172.17.0.3] ************************************************************* GATHERING FACTS *************************************************************** ok: [172.17.0.3] TASK: [common | Install initializtion require software] *********************** changed: [172.17.0.3] TASK: [node_install | Copy Node Software To Redhat Client] ******************** changed: [172.17.0.3] TASK: [node_install | Create Node Install Dir] ******************************** ok: [172.17.0.3] TASK: [node_install | Uncompression Node Software To Redhat Client] *********** changed: [172.17.0.3] TASK: [node_install | Mkdir Soft Link To Redhat Client] *********************** changed: [172.17.0.3] => (item=npm) changed: [172.17.0.3] => (item=node) changed: [172.17.0.3] => (item=forever) TASK: [node_install | Copy Node Test Config To Redhat Client] ***************** changed: [172.17.0.3] TASK: [node_install | Start Node Start App In Redhat Client] ****************** changed: [172.17.0.3] TASK: [node_install | Delete Node compression Software In Redhat Client] ****** changed: [172.17.0.3] PLAY RECAP ******************************************************************** 172.17.0.3 : ok=9 changed=7 unreachable=0 failed=0 real 0m17.806s user 0m5.550s sys 0m0.550s
2、安装后测试

Node install success!3、删除node
09:47:07 # time ansible-playbook node_delete.yml --extra-vars "host=172.17.0.3 user=root" -k SSH password: PLAY [172.17.0.3] ************************************************************* GATHERING FACTS *************************************************************** ok: [172.17.0.3] TASK: [node_delete | Stop Node Service In RedHat Client] ********************** changed: [172.17.0.3] TASK: [node_delete | Delete Redis Install Dir In RedHat Client] *************** changed: [172.17.0.3] TASK: [node_delete | Delete Node Soft Link Script] **************************** changed: [172.17.0.3] => (item=npm) changed: [172.17.0.3] => (item=node) changed: [172.17.0.3] => (item=forever) PLAY RECAP ******************************************************************** 172.17.0.3 : ok=4 changed=3 unreachable=0 failed=0 real 0m8.048s user 0m1.853s sys 0m0.244s
4、删除后测试
09:47:21 # ssh 172.17.0.3 root@172.17.0.3‘s password: Last login: Mon Aug 4 09:44:49 2014 from 172.17.42.1 root@b9a9e6f2caed:~ 09:47:54 # ps -ef|grep node root 12937 12923 0 09:47 pts/0 00:00:00 grep node root@b9a9e6f2caed:~ 09:47:56 # ll /data/ total 12 drwxr-xr-x 4 root root 4096 Jun 26 15:59 mysql drwxr-xr-x 2 root root 4096 Jun 5 10:21 soft drwxr-xr-x 3 root root 4096 Jul 16 13:37 webroot
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/node_install），然后放到/etc/ansible目录里，下面是内容
