客户这里，有很多linux主机，都是centos7的，我们需要定期每天对linux主机进行巡检，然后把巡检结果集中保存，方便对主机状态检查。我收集了一个巡检脚本，如下所示：
#!bin/bash
#主机信息每日巡检
IPADDR=$(ifconfig eth0 | grep ‘\<inet\>‘ | awk ‘{print $2}‘)
#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
[ $(id -u) -gt 0 ] && echo "请用root用户执行此脚本！" && exit 1
centosVersion=$(awk ‘{print $(NF-1)}‘ /etc/redhat-release)
VERSION="2018.08.28"
#日志相关
LOGPATH="$PROGPATH/var/log/HostDailyCheck"
[ -e $LOGPATH ] || mkdir $LOGPATH

脚本会将巡检结果保存到/var/log/HostDailyCheck/路径下，以时间方式进行命名
可以查看巡检内容
配置计划任务，定期每日执行0 23 * * * bash /root/HostDailyCheck.sh
因为日常运维主机是windows，需要配置第三方软件作为服务器。如果是linux的话，配置rsync服务器会比较简单。
下载地址：
https://www.backupassist.com/rsync/
安装cwRsyncServer_4.2.0_Installer
下一步
下一步
这个安装路径，也是作为rsync同步保存的路径
Service account：rsync（新建的一个系统账户）
Type password：123456（密码）
Confirm password：123456（密码）
Install （安装）
Close（关闭），安装完成
开始-设置-控制面板-管理工具-服务
找到RsyncSever选项，双击打开
启动类型：自动
点“启动”
应用-确定
在window7中创建一个存放文件的目录（rsync同步用的），我这里创建的是G:\linux_server_log
右击目录，打开属性——安全，把安装rsyncd时，设置的帐号添加进来，并设置权限为完全控制（我安装rsyncd的时候，设置了帐号是rsync，密码123456）：
修改配置文件：
打开G:\linux_server_log\ICW\rsyncd.conf
修改内容大致如下：
use chroot = false
strict modes = false
hosts allow = *
log file = rsyncd.log
# Module definitions
# Remember cygwin naming conventions : c:\work becomes /cygwin/c/work
#
[172.31.101.12]
path = /cygdrive/g/linux_server_log/172.31.101.12
read only = false
transfer logging = yes
auth users = rsync
secrets file = etc/rsyncd.secrets.txt
UID = 0
GID = 0
[172.31.101.24]
path = /cygdrive/g/linux_server_log/172.31.101.24
read only = false
transfer logging = yes
auth users = rsync
secrets file = etc/rsyncd.secrets.txt
UID = 0
GID = 0
[172.31.101.20]
path = /cygdrive/g/linux_server_log/172.31.101.20
read only = false
transfer logging = yes
auth users = rsync
secrets file = etc/rsyncd.secrets.txt
UID = 0
GID = 0
说明：
1、[172.31.101.12],[172.31.101.24]就是同步文件的目录，我这里以linux主机ip地址方式命名，方便区分，有多个客户端需要进行rsync同步的话就要配置中添加多个配置
2、注意path路径，path = /cygdrive/是固定的，不要改，后面连接的/g/linux_server_log/172.31.101.12，则是我们刚才所建的目录路径，刚才我是建在G盘的，g/linux_server_log/172.31.101.12
其他参数详解：
read only = true #客户端只读
list = no#不允许列出文件
hosts allow=192.168.0.141 #允许连接IP，多个IP中间用英文状态下逗号隔，不限制IP填写*即可
auth users =rsync #允许连接的用户名
secrets file = etc/rsyncd.secrets #存放用户名密码的认证文件路径
建rsync同步帐号密码文件：
进入：G:\linux_server_log\ICW\etc，创建文件：rsyncd.secrets，文件里输入 rsync:123456，rsync是同步帐号，123456是同步密码
cwRsyncServer服务端安装设置完成
基于centos7 安装
yum install rsync -y然后创建rsync客户端同步密码文件
vim /root/rysnc_passwd.txtch
设置密码文件权限
chmod 600 /root/rysnc_passwd.txt测试rsync数据同步
rsync -vza --progress /var/log/HostDailyCheck --port=873 rsync@172.31.101.110::172.31.101.45 --password-file=/root/rysnc_passwd.txt
同步正常
关于rsync工具使用和命令参数，参考https://jaywcjlove.gitee.io/linux-command/c/rsync.html
然后我们编写同步脚本
touch /root/rysncbak.sh
cat << EOF > /root/rysncbak.sh
#!/bin/sh
rsync -vza --progress /var/log/HostDailyCheck --port=873 rsync@172.31.101.110::172.31.101.45 --password-file=/root/rysnc_passwd.txt
EOF
chmod +x /root/rysncbak.sh脚本完成后，开启加护任务，每天定时执行
crontab -e按照如下方式编写计划任务
至此每天都会定时运行主机巡检脚本，同时会将巡检结果同步
完成所有的配置后，我们每天就可以收集到所有linux主机日志状态检查
工作又轻松了
windows上配置rsync服务器收集linux主机巡检报告
