ansible部署tomcat及 include机制

1、本文尝试着使用ansible部署tomcat，test为测试工程

roles如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

[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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

[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 重新命名为 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:

1 2 3 4 5

[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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

核实测试主机：

1 2 3 4 5

[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]$

1 2 3 4 5

[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]$

测试更新操作：

1.1、修改测试文件：

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

执行：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

2、ansible 中的include 机制

测试目的，可以随意指定要操作的主机组 和 要操作的状态

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

[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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[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

上面是创建文件，我们也可以删除操作

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

[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机及状态 （对 db 主机组操作)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

[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]$

删除操作：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

[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]$
