通过ansible的playbook实现服务器批量初始化工作，会节省大量时间，提高工作效率
ansible模块目录结构
$ tree roles/ roles/ └── base ├── defaults ├── files │ ├── puppet.conf │ ├── yum65.repo │ ├── yum67.repo │ └── yum.repo ├── handlers │ └── main.yml ├── meta ├── tasks │ ├── chkconfig.yml │ ├── hostname.yml │ ├── main.yml │ ├── ntpd.yml │ ├── puppet.yml │ ├── repo.yml │ └── route.yml ├── templates │ ├── hosts.j2 │ └── static-routes.j2 └── vars └── main.yml
入口文件的site.yml
$ more site.yml --- - hosts: all remote_user: test become: yes become_method: sudo roles: - base
模版文件template
修改主机名 $ more base/templates/hosts.j2 127.0.0.1 {{ ansible_fqdn }} localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 {{ ansible_fqdn }} localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.1 puppet.server 添加静态路由，需要重启网络 $ more base/templates/static-routes.j2 any net 10.0.0.0/8 gw {{ gateway }} any net 172.0.0.0/8 gw {{ gateway }} any net 192.168.1.0/24 gw {{ gateway }}
可以在base/vars/main.yml中定义变量，由于环境特殊，我在命令行中使用变量。
yml中定义使用变量的格式如下
name:value
task中的入口文件
$ more base/tasks/main.yml --- - include: ntpd.yml - include: repo.yml - include: route.yml - include: hostname.yml - include: chkconfig.yml - include: puppet.yml
时间同步
$ more base/tasks/ntpd.yml --- - name: sync datatime command: /usr/sbin/ntpdate 202.120.2.101 - name: sync hwclock command: /sbin/hwclock -w
更具不同系统版本配置yum源
$ more base/tasks/repo.yml --- - name: configure RedHat5 yum repo copy: force=yes src=yum.repo dest=/etc/yum.repos.d/rhel-debuginfo.repo owner=root group=root mode=0644 when: ansible_distribution_major_version == '5' - name: configure RedHat6.5 yum repo copy: force=yes src=yum65.repo dest=/etc/yum.repos.d/rhel-debuginfo.repo owner=root group=root mode=0644 when: ansible_distribution_version == '6.5' - name: configure RedHat6.7 yum repo copy: force=yes src=yum67.repo dest=/etc/yum.repos.d/rhel-debuginfo.repo owner=root group=root mode=0644 when: ansible_distribution_version == '6.7'
配置路由
$ more base/tasks/route.yml - name: config static route template: force=yes src=static-routes.j2 dest=/etc/sysconfig/static-routes owner=root group=root mode=0644 notify: restart network
批量配置服务器的hostname(动态inventory脚本实现)
$ more base/tasks/hostname.yml --- - name: install facter yum: name=facter state=latest - name: install rubygem-json yum: name=rubygem-json state=latest - hostname: name={{ hostname }} - name : gather facts again setup : - name: config hosts template: force=yes src=hosts.j2 dest=/etc/hosts owner=root group=root mode=0644
关闭iptables，sendmail和selinux
$ more base/tasks/chkconfig.yml - name: chkconfig off iptables shell: /sbin/chkconfig iptables off - name: stop iptables service: name=iptables state=stopped - name: chkconfig off sendmail shell: /sbin/chkconfig sendmail off - name: stop sendmail service: name=sendmail state=stopped - name: stop selinux command: /sbin/setenforce 0
