ansible批量部署巡检
二、ansible安装 有脚本可以 直接传公钥
1、 准备环境----关闭防火墙和selinux
环境:
主机:4台 1个控制节点 3个被控制节点
解析:本地互相解析(所有机器)
vim /etc/hosts
配置ssh公钥认证:控制节点需要发送ssh公钥给所有被控制节点
[[email protected] ~]# ssh-keygen -p -f /root/.ssh/id_rsa -p 跳过密码 -f 存放目录
[[email protected] ~]# ssh-copy-id -i 192.168.1.10 #所有被控节点机器
所有机器:
systemctl stop firewalld && setenforce 0
安装
安装:控制节点
配置EPEL网络yum源
[[email protected] ~]# yum install -y epel-release
安装ansible
[[email protected] ~]# yum install -y ansible
3.查看版本
[[email protected] ~]# ansible --version
4.看帮助
[[email protected] ~]# ansible --help


ansible基础----inventory主机清单
官方文档: http://docs.ansible.com/ansible/intro_inventory.html#>
inventory文件通常用于定义要管理主机的认证信息,例如ssh登录用户名、密码以及key相关信息。
查看配置文件:
[[email protected] ~]# rpm -qc ansible
/etc/ansible/ansible.cfg
/etc/ansible/hosts #ansible主机清单文件
-q:—query查询
1.主配置文件:
/etc/ansible/ansible.cfg #主要设置一些ansible初始化的信息,比如日志存放路径、模块、等配置信息
2.主机清单文件:
默认位置/etc/ansible/hosts 这个比较重要
1.主配置文件:
/etc/ansible/ansible.cfg #主要设置一些ansible初始化的信息,比如日志存放路径、模块、等配置信息
2.主机清单文件:
默认位置/etc/ansible/hosts 这个比较重要

主配置文件
步骤;vim /etc/ansible/hosts 主清单文件
语法;ansible web3 -m ping
主语法 主机名 -m 模块 -o 在一行显示

定义一个组,可以有多个主机
步骤;vim /etc/ansible/hosts 主清单文件
语法;ansible webss -m ping
主语法 总组名 -m 模块 -o 在一行显示

playbook剧本详解


检测语法是否合格; ansible-playbook --syntax-check wenjian.yml
playbook: wenjian.yml 合格语法

这里主要用到两个功能,fetch和copy,其中copy是将文件拷贝到远程机器,二fetch是把文件从远程拷贝到本机,下面分别做说明(需要注意的是不支持文件夹的拷贝):
实现需要巡检的节点免密登陆到ansible的服务器
ssh免密登录
1、简洁操作
主机A免密码登录主机B:将A的公钥上传到主机B
1.1、 在主机A创建密钥对
ssh-keygen #创建证书
#然后均回车(选择默认)

1.2、将公钥文件上传至免登录主机B
ssh-copy-id -i ~/.ssh/id_rsa.pub -p 50028 [email protected](端口不是22的情况)
ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.198.132

编写传输巡检日志脚本
vim scp.sh
# !/bin/sh
#echo "$processid 请管理员注意,99.88 拼接服务暂停服务 " >>monitor.log
#echo 启动了 | mailx -s "test" [email protected] -f [email protected]
#cd /email/file/error
filelist=`ls /xunjian/log`
for file in $filelist
do
echo $file
scp /xunjian/log/$file [email protected]:/xunjian/
rm -rf /xunjian/log/$file
done
编写巡检脚本
vim xunjian.sh
#!/bin/bash
#主机信息每日巡检
IPADDR=$(ifconfig eth0|grep 'inet addr'|awk -F '[ :]' '{print $13}')
#环境变量PATH没设好,在cron里执行时有很多命令会找不到
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
source /etc/profile

Debian上Crontab的使用
配置计划任务每天执行
一、Crontab的安装
*1、Debian下面安装Crontab*
apt-get install cron //大部分情况下Debian都已安装。
/etc/init.d/cron restart //重启Crontab
二、Crontab使用方法
1、查看crontab定时执行任务列表
crontab -l
2、添加crontab定时执行任务
crontab -e
输入crontab任务命令时可能会因为crontab默认编辑器的不同。

如上图所示为nano编辑器,使用比较简单,直接在文件末尾按crontab命令格式输入即可,Ctrl+x退出,再输y 回车保存。
另外一种是vi编辑器,首先按i键,在文件末尾按crontab命令格式输入,再按ESC键,再输入:wq 回车即可。
测试计划任务执行成功
