篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ansible安装tomcat8 最终版相关的知识,希望对你有一定的参考价值。
假如你要在一台机器安装多个tomcat或者安装多台tomcat,你可以选择
假设现在tomcat有三个,分别为cxx,wxx,sxx
多建立对应的yml文件,一个项目一个
copy.yml,install.yml,delete.yml 分别一个
我选择第二种方法,变量可以定义在一个文件中
借用ansible生成动态的hosts优势
#!/usr/bin/python # coding:utf-8 import sqlite3 import sys try: import json except ImportError: import simplejson as json def grouplist(): inventory = {} inventory[‘local‘] = [‘127.0.0.1‘] sfile=‘/etc/ansible/books.txt‘ with open(sfile,‘rb‘) as f: for i in f.readlines(): group=i.strip().split()[0] name=i.strip().split()[1] if not group in inventory: inventory[group] = { ‘hosts‘: [] } inventory[group][‘hosts‘].append(name) print json.dumps(inventory, indent=4) def hostinfo(name): vars = {} vars = { ‘admin‘: ‘Jane Jolie‘, ‘datacenter‘: 1 } print json.dumps(vars, indent=4) if __name__ == ‘__main__‘: if len(sys.argv) == 2 and (sys.argv[1] == ‘--list‘): grouplist() elif len(sys.argv) == 3 and (sys.argv[1] == ‘--host‘): hostinfo(sys.argv[2]) else: print "Usage: %s --list or --host <hostname>" % sys.argv[0] sys.exit(1)
这个配置文件,指明端口和分组。cxx就是分组,后面的端口,你懂的。
cat books.txt cxx 192.168.1.3 sc_tomcat 8005 8080 wxx 192.168.1.3 sc_tomcat 8006 8081 sxx 192.168.1.3 sc_tomcat 8007 8082
先来说ansible部分吧
目录结构
[[email protected] roles]# tree . ├── copy │ ├── default │ ├── files │ │ └── ROOT │ │ └── test.html │ ├── meta │ │ └── test │ │ └── test.html │ └── tasks │ ├── copy.yml │ ├── delete.yml │ ├── install.yml │ ├── main.bak │ ├── main.yml │ ├── main.yml.v1 │ └── main.yml.v2 ├── delete │ ├── default │ ├── files │ │ └── ROOT │ │ └── test.html │ ├── handlers │ │ └── main.yml │ ├── meta │ │ └── test │ │ └── test.html │ ├── tasks │ │ ├── copy.yml │ │ ├── delete.yml │ │ ├── install.yml │ │ ├── main.bak │ │ ├── main.yml │ │ ├── main.yml.v1 │ │ └── main.yml.v2 │ ├── templates │ │ ├── server.xml │ │ └── tomcat.sh │ └── vars │ └── main.yml └── install ├── default ├── files │ └── ROOT │ └── test.html ├── handlers │ └── main.yml ├── meta │ └── test │ └── test.html ├── tasks │ ├── copy.yml │ ├── delete.yml │ ├── install.yml │ ├── main.bak │ ├── main.yml │ ├── main.yml.v1 │ └── main.yml.v2 ├── templates │ ├── server.xml │ └── tomcat.sh └── vars └── main.yml
对比以前的变化是
cd /etc/ansible/tomcat/roles install中的install.yml 文件改变了 cd /etc/ansible/tomcat/roles/install/tasks [[email protected] tasks]# cat install.yml - name: pro file: path=/opt/apps/{{cxx_pro_dir}} state=directory - name: tar shell: chdir=/opt/ea rm -rf {{cxx_dir}} && cp -r tomcat {{cxx_dir}} - name: copy server.xml template: src=server.xml dest=/opt/ea/{{cxx_dir}}/conf/ force=yes mode=0644 - name: rm webapps file: dest=/opt/ea/{{cxx_dir}}/webapps/ state=absent - name: copy tomcat.sh copy: src=/opt/src/tomcat.sh dest=/opt/ea/{{cxx_pro_dir}}.sh owner=tomcat group=tomcat - name: modify tomcat.sh shell: chdir=/opt/ea sed -i ‘s%/ea/tomcat%/ea/{{cxx_dir}}%g‘ {{cxx_pro_dir}}.sh - name: modify file: path=/opt/ea/{{cxx_dir}}/ owner=tomcat group=tomcat mode=0755 - name: chown file: path=/opt/ea/{{cxx_dir}}/ state=directory recurse=yes owner=tomcat group=tomcat - name: 首次启动tomcat shell: cd /opt/ea && source /etc/profile && sudo -i -u tomcat nohup sh {{cxx_pro_dir}}.sh start & - name: copy test copy: src=/etc/ansible/tomcat/roles/install/meta/test dest=/opt/apps/{{cxx_pro_dir}}/
cd /etc/ansible/tomcat/roles/install/vars 变量文件有大改变 说明cxx_pro_dir 也可以指明wxx_pro_dir,你可以把它当做变量,上面的install.yml引用这个变量而已。 [[email protected] vars]# cat main.yml cxx_pro_dir: "{{ cxx_pro_dir }}" cxx_dir: "{{ cxx_dir }}" cxx_port1: "{{ cxx_port1 }}" cxx_port2: "{{ cxx_port2 }}"
ansible部分完结。
因为有好多主机,不想手动书写ansible执行文件,可以用python脚本自动生成
主要想自动生成这样的脚本
ansible-playbook -i /etc/ansible/test.py copy.yml --extra-vars "host=192.168.1.3"
ansible-playbook -i /etc/ansible/test.py install.yml --extra-vars "host=192.168.1.3 cxx_pro_dir=cxx cxx_dir=cxx_tomcat cxx_port1=8005 cxx_port2=8080"
以下python脚本,读取生成的
声明 什么cxx都是变量,你可以随便取名字
# !/usr/bin/env python # coding:utf-8 #import sqlite3 import sys try: import json except ImportError: import simplejson as json dfile=‘/etc/ansible/ansible.sh
‘‘‘ cxx 172.29.12.196 sc_tomcat 8005 8080 ‘‘‘ def ansiblec(host,cxx_pro_dir=None,cxx_dir=None,cxx_port1=None,cxx_port2=None): if cxx_port1==None: stringa = ‘ansible-playbook -i /etc/ansible/test.py copy.yml --extra-vars "host=%s"‘ %(host) return stringa else: stringb = ‘ansible-playbook -i /etc/ansible/test.py install.yml --extra-vars "host=%s cxx_pro_dir=%s cxx_dir=%s cxx_port1=%s cxx_port2=%s"‘ %(host,cxx_pro_dir,cxx_dir,cxx_port1,cxx_port2) return stringb def grouplist(): inventory = {} sfile = ‘/etc/ansible/books.txt‘ with open(sfile, ‘rb‘) as f: iplist=[] glist=[] for i in f.readlines(): group = i.strip().split()[0] grouptomcat=group+"_"+"tomcat" name = i.strip().split()[1] cxx_port1=i.strip().split()[3] cxx_port2=i.strip().split()[4] iplist.append(ansiblec(name)) glist.append(ansiblec(name,group,grouptomcat,cxx_port1,cxx_port2)) # if not group in inventory: # inventory[group] = { # ‘hosts‘: [] # } # inventory[group][‘hosts‘].append(name) # for ip in inventory.iteritems(): # ipt= ip[1][‘hosts‘][0] ipset=set(iplist) gset=set(glist) # print json.dumps(inventory, indent=4) with open(dfile,‘wb‘) as f1: for i in ipset: line = str(i) + "\n" f1.write(line) for i in gset: line = str(i) + "\n" f1.write(line) f1.close() def hostinfo(name): vars = {} vars = { ‘admin‘: ‘Jane Jolie‘, ‘datacenter‘: 1 } print json.dumps(vars, indent=4) if __name__ == ‘__main__‘: grouplist()
直接执行这个脚本后,自动生成
/etc/ansible/ansible.sh
里面包含就是
ansible-playbook -i /etc/ansible/test.py copy.yml --extra-vars "host=192.168.1.3"
ansible-playbook -i /etc/ansible/test.py install.yml --extra-vars "host=192.168.1.3 cxx_pro_dir=cxx cxx_dir=cxx_tomcat cxx_port1=8005 cxx_port2=8080"
这样,通过两个python脚本,只需要一个配置文件,写明端口和应用名称,自动生成创建脚本。
剩余没有解决的问题
1.root权限,ansible最好不要用root权限
2.context.xml没有加入到模板里面去,主要做集群,可以自己添加
3.lib包,比如集群包没有,主要做session共享的集群包
4.没有自动启动脚本,这个需要写下tomcat的启动脚本
这是自己个人的想法,比以前快点。
