ansible部署tomcat及 include机制

一、本文尝试着使用ansible部署tomcat，test为测试工程

roles以下：

[lansgg@node1 ansible_playbook]$ pwd
/opt/lansgg/ansible_playbook
[lansgg@node1 ansible_playbook]$ ls
hosts  roles  site.yml
[lansgg@node1 ansible_playbook]$ tree
.
├── hosts
├── roles
│   └── http
│       ├── default
│       ├── files

11 directories, 10 files
[lansgg@node1 ansible_playbook]$

main.yml 以下：

[lansgg@node1 tasks]$ cat main.yml 
- name: 将jdk压缩包copy到远程主机 jdk-7u72-linux-x64.tar.gz
  copy: src=jdk-7u72-linux-x64.tar.gz dest=/opt/lansgg/
- name: 解压jdk压缩包 jdk-7u72-linux-x64.tar.gz
  shell: chdir=/opt/lansgg tar zxvf jdk-7u72-linux-x64.tar.gz
- name: 将tomcat压缩包copy到远程主机 apache-tomcat-7.0.68.tar.gz
  copy: src=apache-tomcat-7.0.68.tar.gz dest=/opt/lansgg
- name: 解压tomcat压缩包
  shell: chdir=/opt/lansgg tar zxvf apache-tomcat-7.0.68.tar.gz
- name: 将tomcat压缩包 从新命名为 tomcat
  shell: chdir=/opt/lansgg mv apache-tomcat-7.0.68 tomcat
- name: 将用户的 .bashrc 模板文件 copy 到远程主机
  copy: src=.bashrc dest=`ansible_user_dir`/
- name: 将用户的 .bash_profile 模板文件 copy 到远程主机
  copy: src=.bash_profile dest=`ansible_user_dir`/
- name: 首次启动tomcat
  shell: chdir=`ansible_user_dir`/tomcat/bin nohup ./startup.sh &
- name: 将 test 工程 copy 到远程主机
  copy: src=/opt/lansgg/ansible_playbook/roles/http/meta/test dest=`ansible_user_dir`/tomcat/webapps/
  tags: 
   - updateconf
  notify:
   - stop tomcat service
   - start tomcat service
- name: 将某些模板文件 copy 到远程主机
  template: src=test.yml dest=`ansible_user_dir`/tomcat/webapps/test/test.html

handlers:

[lansgg@node1 handlers]$ more main.yml 
- name: stop tomcat service
  shell: "ps -ef |grep `ansible_user_dir`/tomcat |grep -v grep |awk '{print $2}' |xargs kill -9"
- name: start tomcat service
  shell: chdir=`ansible_user_dir`/tomcat/bin nohup ./startup.sh &

执行结果：

[lansgg@node1 ansible_playbook]$ ansible-playbook -i hosts site.yml

核实测试主机：

[lansgg@node1 ansible_playbook]$ ansible -i hosts http -m shell -a 'ps -ef|grep tomcat |grep -v grep'
192.168.100.131 | success | rc=0 >>

[lansgg@node1 ansible_playbook]$

[lansgg@node1 ansible_playbook]$ curl http://192.168.100.131:8080/test/test.html
this is a test 
hostname:v2.lansgg.com
abcdefg
[lansgg@node1 ansible_playbook]$

测试更新操做：

1.一、修改测试文件：

[lansgg@node1 ansible_playbook]$ echo "abcdefg" >> roles/http/meta/test/test.html

执行：

[lansgg@node1 ansible_playbook]$ ansible-playbook -i hosts site.yml --tags=updateconf

二、ansible 中的include 机制

测试目的，能够随意指定要操做的主机组 和 要操做的状态

[lansgg@node1 ansible_playbook]$ pwd
/opt/lansgg/ansible_playbook
[lansgg@node1 ansible_playbook]$ tree
.
├── hosts
├── roles
│   └── test
│       └── tasks
│           ├── del.yml
│           ├── main.yml
│           └── touch.yml
└── test.yml

3 directories, 5 files
[lansgg@node1 ansible_playbook]$

tasks：

[lansgg@node1 ansible_playbook]$ cat roles/test/tasks/touch.yml 
- name: touch file
  shell: touch /tmp/123
[lansgg@node1 ansible_playbook]$ cat roles/test/tasks/del.yml 
- name: del file
  shell: rm /tmp/123
[lansgg@node1 ansible_playbook]$ cat roles/test/tasks/main.yml 
- name: include touch yml
  include: touch.yml
  when: "state=='touch'"
- name: include del yml
  include: del.yml
  when: "state=='del'"
[lansgg@node1 ansible_playbook]$ 
[lansgg@node1 ansible_playbook]$ cat test.yml 
- hosts: '`testhost`'
  remote_user: lansgg
  roles:
   - test
[lansgg@node1 ansible_playbook]$ cat hosts
[http]
192.168.100.131
[db]
192.168.100.132
[lansgg@node1 ansible_playbook]$

执行并查看结果：

[lansgg@node1 ansible_playbook]$ ansible-playbook -i hosts test.yml --extra-vars "testhost=http state=touch"

PLAY [http] ******************************************************************* 

GATHERING FACTS *************************************************************** 
ok: [192.168.100.131]

TASK: [test | touch file] ***************************************************** 
changed: [192.168.100.131]

TASK: [test | del file] ******************************************************* 
skipping: [192.168.100.131]

PLAY RECAP ******************************************************************** 
192.168.100.131            : ok=2    changed=1    unreachable=0    failed=0

上面是建立文件，咱们也能够删除操做

[lansgg@node1 ansible_playbook]$ ansible-playbook -i hosts test.yml --extra-vars "testhost=http state=del"

PLAY [http] ******************************************************************* 

GATHERING FACTS *************************************************************** 
ok: [192.168.100.131]

TASK: [test | touch file] ***************************************************** 
skipping: [192.168.100.131]

TASK: [test | del file] ******************************************************* 
changed: [192.168.100.131]

PLAY RECAP ******************************************************************** 
192.168.100.131            : ok=2    changed=1    unreachable=0    failed=0   

[lansgg@node1 ansible_playbook]$ ansible -i hosts http -m shell -a 'ls -l /tmp/'
192.168.100.131 | success | rc=0 >>
total 0

[lansgg@node1 ansible_playbook]$

能够以命令式的方式控制要操做的主机及状态 （对 db 主机组操做)

[lansgg@node1 ansible_playbook]$ ansible-playbook -i hosts test.yml --extra-vars "testhost=db state=touch"

PLAY [db] ********************************************************************* 

GATHERING FACTS *************************************************************** 
ok: [192.168.100.132]

TASK: [test | touch file] *****************************************************

TASK: [test | del file] ******************************************************* 
skipping: [192.168.100.132]

PLAY RECAP ******************************************************************** 
192.168.100.132            : ok=2    changed=1    unreachable=0    failed=0   

[lansgg@node1 ansible_playbook]$ ansible -i hosts db -m shell -a 'ls -l /tmp/'
192.168.100.132 | success | rc=0 >>
total 0
