Ansible-下部
ansible-playbook
playbook是由一个或多个模块组成的，使用多个不同的模块，完成一件事情。
ansible软件特点
可以实现批量管理
可以实现批量部署
ad-hoc(批量执行命令)---针对临时性的操作
ansible clsn -m command -a "hostname" <- 批量执行命令举例
编写剧本-脚本(playbook)---针对重复性的操作
ansible核心功能
pyYAML-----用于ansible编写剧本所使用的语言格式（saltstack---python）
rsync-ini语法 sersync-xml语法 ansible-pyYAML语法
paramiko---远程连接与数据传输
Jinja2-----用于编写ansible的模板信息
剧本编写规则说明
YAML三板斧
缩进
YAML使用一个固定的缩进风格表示层级结构,每个缩进由两个空格组成, 不能使用tabs
冒号
以冒号结尾的除外，其他所有冒号后面所有必须有空格。
短横线
表示列表项，使用一个短横杠加一个空格。
多个项使用同样的缩进级别作为同一列表。
剧本书写格式
- hosts: 172.16.1.7 处理指定服务器 (空格)hosts:(空格)172.16.1.7task: 剧本所要干的事情; (空格)(空格)task:- name: （两个空格）-（空格）name:command: echo hello clsn linux （四个空格）command:(空格) 剧本格式示例[root@m01 ansible-playbook]# vim rsync.yaml- hosts: 172.16.1.41 tasks: - name: Install Rsync yum: name=rsync state=installed剧本检查方法

剧本编写内容扩展：剧本任务编写多个任务
- hosts: all tasks: - name: restart-network cron: name='restart network' minute=00 hour=00 job='/usr/sbin/ntpdate time.nist.gov >/dev/null 2>&1' - name: sync time cron: name='sync time' minute=*/5 job="/usr/sbin/ntpdate pool.ntp.com >/dev/null 2>&1"剧本编写内容扩展：剧本任务编写多个主机- hosts: 172.16.1.7 tasks: - name: restart-network cron: name='restart network' minute=00 hour=00 job='/usr/sbin/ntpdate time.nist.gov >/dev/null 2>&1' - name: sync time cron: name='sync time' minute=*/5 job="/usr/sbin/ntpdate pool.ntp.com >/dev/null 2>&1"- hosts: 172.16.1.31 tasks: - name: show ip addr to file shell: echo $(hostname -i) >> /tmp/ip.txt剧本编写方式
多主机单任务编写方式
多主机多任务编写方式
不同主机多任务编写方式

目录规划
[root@m01 ~]# mkdir /etc/ansible/ansible_playbook/{file,conf,scripts} -p [root@m01 ~]# tree /etc/ansible/ansible_playbook//etc/ansible/ansible_playbook/├── conf└── file└── scripts需提前准备好的文件
rsync配置文件
准备对应的配置文件存放至/etc/ansible/ansible_playbook/conf/

准备nfs配置文件exports
[root@m01 ansible_playbook]# cat /etc/ansible/ansible_playbook/conf/nfs_exports /data/ 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)Sersync软件包

[root@m01 ansible_playbook]# ll /etc/ansible/ansible_playbook/file/-rw-r--r-- 1 root root 727290 Aug 1 12:04 sersync.tar.gzsersync配置文件
准备sersync实时同步的配置文件

基础环境：所有机器统一的配置
1.需要关闭firewalld以及selinux、epel仓库、ssh端口、优化基础配置
2.需要安装rsync和nfs-utils
3.准备www用户
4.需要准备/etc/rsync.pass密码文件
5.需要准备全网备份脚本
基础的playbook剧本
[root@m01 ansible_playbook]# cat base.yaml - hosts: all tasks: - name: Install Epel Repos get_url: url=http://mirrors.aliyun.com/repo/epel-7.repo dest=/etc/yum.repos.d/epel.repo - name: Install Rsync Nfs-Utils yum: name=rsync,nfs-utils state=installed - name: Create Group WWW group: name=www gid=666 - name: Create User WWW user: name=www uid=666 group=666 create_home=no shell=/sbin/nologin - name: Create Rsync_Client_Pass copy: content='1' dest=/etc/rsync.pass mode=600 - name: Create Scripts Directory file: path=/server/scripts recurse=yes state=directory - name: Push File Scripts copy: src=./scripts/rsync_backup_md5.sh dest=/server/scripts/ - name: Crontable Scripts cron: name="backup scripts" hour=01 minute=00 job="/bin/bash /server/scripts/rsync_backup_md5.sh &>/dev/null"应用环境：Rsync
1.安装rsync
2.配置rsync（配置变更，一定要进行重载操作）
3.创建虚拟用户，权限调整
4.创建目录/data/ /backup
5.启动rsync
6.配置邮箱->邮箱的发件人->校验的脚本
[root@m01 ansible_playbook]# cat rsync.yaml - hosts: backup tasks: - name: Installed Rsync Server yum: name=rsync,mailx state=installed - name: configure Rsync Server copy: src=./conf/rsyncd.conf dest=/etc/rsyncd.conf notify: Restart Rsync Server - name: Create Virt User copy: content='rsync_backup:1' dest=/etc/rsync.password mode=600 - name: Create Data file: path=/data state=directory recurse=yes owner=www group=www mode=755 - name: Create Backup file: path=/backup state=directory recurse=yes owner=www group=www mode=755 - name: Start RsyncServer service: name=rsyncd state=started enabled=yes - name: Push Check Scripts copy: src=./scripts/rsync_check_backup.sh dest=/server/scripts/ - name: Crond Check Scripts cron: name="check scripts" hour=05 minute=00 job="/bin/bash /server/scripts/rsync_check_backup.sh &>/dev/null"应用环境：NFS
1.安装nfs-utils
2.配置nfs （当修改了配置，触发重载操作）
3.创建目录，授权
4.启动
[root@m01 ansible_playbook]# cat nfs.yaml - hosts: nfs tasks: - name: Installed Nfs Server yum: name=nfs-utils state=installed - name: Configure Nfs Server copy: src=./conf/exports dest=/etc/exports notify: Restart Nfs Server - name: Create Share Data file: path=/data state=directory recurse=yes owner=www group=www mode=755 - name: Start Nfs Server service: name=nfs-server state=started enabled=yes handlers: - name: Restart Nfs Server service: name=nfs-server state=restarted应用环境：Sersync
1.下载sersync
2.解压，改名，配置
3.启动
[root@m01 ansible_playbook]# cat sersync.yaml - hosts: nfs tasks: - name: Scp Sersync copy: src=./file/sersync2.5.4_64bit_binary_stable_final.tar.gz dest=/usr/local/sersync.tar.gz - name: Zip shell: cd /usr/local && tar xf sersync.tar.gz && mv GNU-Linux-x86 sersync args: creates: /usr/local/sersync - name: configure Sersync copy: src=./conf/confxml.xml dest=/usr/local/sersync/ - name: Start Sersync shell: /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml应用环境：WEB
挂载nfs共享的目录
[root@m01 ansible_playbook]# cat web.yaml - hosts: web tasks: - name: Mount NFS Server Share Data mount: src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=mounted包含include
