监控到Centos7-001机器上的网站内容发生变化时,就同步Centos7-001:/var/www/html/目录到Centos7-002上
Centos7-001上所做的操作
- 安装 rsync
# yum install rsync -y
-
生成密钥对
[[email protected] ~]# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory ‘/root/.ssh‘. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: SHA256:3e6TNDwQTTP5BeDBusXs/7Ma/sx7LFVmSpa8PVEDNaY [email protected] The key‘s randomart image is: +---[RSA 2048]----+ | +*++= | | ..++o.+| | =.E oo| | .o.+ *.+| | S .*.o *o| | ..* o.o| | ..* o.| | .+ *.o| | .+oO*| +----[SHA256]-----+
- 传递公钥给 Centos7-002(可查看Centos机器上是否生成 /root/.ssh/authorized_keys文件)
# ssh-copy-id [email protected]
Are you sure you want to continue connecting (yes/no)? yes
[email protected]‘s password:
- 安装 inotify-tools 工具
# yum install epel-release -y
# yum install inotify-tools -y
# rpm -q inotify-tools
- 利用 inotifywait 命令监控本机的 /var/www/html/目录,如发生变化就同步到Centos7-002:/web_backup上(写一个脚本 inotify.sh),在后台运行此脚本(Centos7-002上需要先安装 rsync)
[[email protected] ~]# cat inotify.sh
#!/bin/bash
dir=/var/www/html/
remote_dir=192.168.195.129:/web_backup
inotifywait -rqm -e modify,create,move,delete $dir | while read a b c
do
rsync -azP --delete $dir [email protected]$remote_dir
done
- 在本地上的/var/www/html/创建文件、目录,删除文件、目录,修改文件、目录
cd /var/www/html/ cp -f /etc/passwd ./ mkdir apeng mkdir aa echo inotify > aa/test.txt
Centos7-002上所做的操作
- 安装 rsync
# yum install rsync -y
- 观察本机的 /web-back目录
