1、本文嘗試着使用ansible部署tomcat，test爲測試工程
roles如下：
[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 │ │ ├── apache-tomcat-7.0.68.tar.gz │ │ ├── jdk-7u72-linux-x64.tar.gz │ │ └── ROOT │ │ └── test.html │ ├── handlers │ │ └── main.yml │ ├── meta │ │ └── test │ │ └── test.html │ ├── tasks │ │ ├── bak.yml │ │ └── main.yml │ ├── templates │ │ └── test.yml │ └── vars └── site.yml 11 directories, 10 files [lansgg@node1 ansible_playbook]$
main.yml 如下：
[lansgg@node1 tasks]$ cat main.yml - name: 將jdk壓縮包copy到遠程主機 jdk-7u72-linux-x64.tar.gz copy: src=jdk-7u72-linux-x64.tar.gz dest=/opt/lansgg/ - name: 解壓jdk壓縮包 jdk-7u72-linux-x64.tar.gz shell: chdir=/opt/lansgg tar zxvf jdk-7u72-linux-x64.tar.gz - name: 將tomcat壓縮包copy到遠程主機 apache-tomcat-7.0.68.tar.gz copy: src=apache-tomcat-7.0.68.tar.gz dest=/opt/lansgg - name: 解壓tomcat壓縮包 shell: chdir=/opt/lansgg tar zxvf apache-tomcat-7.0.68.tar.gz - name: 將tomcat壓縮包 重新命名爲 tomcat shell: chdir=/opt/lansgg mv apache-tomcat-7.0.68 tomcat - name: 將用戶的 .bashrc 模板文件 copy 到遠程主機 copy: src=.bashrc dest=`ansible_user_dir`/ - name: 將用戶的 .bash_profile 模板文件 copy 到遠程主機 copy: src=.bash_profile dest=`ansible_user_dir`/ - name: 首次啓動tomcat shell: chdir=`ansible_user_dir`/tomcat/bin nohup ./startup.sh & - name: 將 test 工程 copy 到遠程主機 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: 將某些模板文件 copy 到遠程主機 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 &執行結果：

覈實測試主機：
[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 54034 1 6 13:09 ? 00:00:06 /opt/lansgg/jdk1.7.0_72/jre/bin/java -Djava.util.logging.config.file=/opt/lansgg/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/opt/lansgg/tomcat/endorsed -classpath /opt/lansgg/tomcat/bin/bootstrap.jar:/opt/lansgg/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/opt/lansgg/tomcat -Dcatalina.home=/opt/lansgg/tomcat -Djava.io.tmpdir=/opt/lansgg/tomcat/temp org.apache.catalina.startup.Bootstrap start [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]$
測試更新操作：
1.1、修改測試文件：
[lansgg@node1 ansible_playbook]$ echo "abcdefg" >> roles/http/meta/test/test.html
執行：
[lansgg@node1 ansible_playbook]$ ansible-playbook -i hosts site.yml --tags=updateconf PLAY [http] ******************************************************************* GATHERING FACTS *************************************************************** ok: [192.168.100.131] TASK: [http | 將 test 工程 copy 到遠程主機] *************************** changed: [192.168.100.131] NOTIFIED: [http | stop tomcat service] **************************************** changed: [192.168.100.131] NOTIFIED: [http | start tomcat service] *************************************** changed: [192.168.100.131] PLAY RECAP ******************************************************************** 192.168.100.131 : ok=4 changed=3 unreachable=0 failed=0 [lansgg@node1 ansible_playbook]$ [lansgg@node1 ansible_playbook]$ curl http://192.168.100.131:8080/test/test.html this is a test hostname:hostname 1111111111111111111111111111 [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 54236 1 24 13:11 ? 00:00:05 /opt/lansgg/jdk1.7.0_72/jre/bin/java -Djava.util.logging.config.file=/opt/lansgg/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/opt/lansgg/tomcat/endorsed -classpath /opt/lansgg/tomcat/bin/bootstrap.jar:/opt/lansgg/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/opt/lansgg/tomcat -Dcatalina.home=/opt/lansgg/tomcat -Djava.io.tmpdir=/opt/lansgg/tomcat/temp org.apache.catalina.startup.Bootstrap start [lansgg@node1 ansible_playbook]$
2、ansible 中的include 機制
測試目的，可以隨意指定要操作的主機組 和 要操作的狀態
[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]$
執行並查看結果：
[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
上面是創建文件，我們也可以刪除操作
[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]$
可以以命令式的方式控制要操作的主機及狀態 （對 db 主機組操作)
[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] ***************************************************** changed: [192.168.100.132] 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 -rw-rw-r-- 1 lansgg lansgg 0 Mar 9 16:20 123 [lansgg@node1 ansible_playbook]$
刪除操作：
[lansgg@node1 ansible_playbook]$ ansible-playbook -i hosts test.yml --extra-vars "testhost=db state=del" PLAY [db] ********************************************************************* GATHERING FACTS *************************************************************** ok: [192.168.100.132] TASK: [test | touch file] ***************************************************** skipping: [192.168.100.132] TASK: [test | del file] ******************************************************* changed: [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 [lansgg@node1 ansible_playbook]$
