swd fin private 創建文件 process tp5 做的 color done 監控到Centos7-001機器上的網站內容發生變化時，就同步Centos7-001:/var/www/html/目錄到Centos7-002上
Centos7-001上所做的操作
- 安裝 rsync
# yum install rsync -y-
生成密鑰對
[root@centos7-001 ~]# 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 root@centos7-001 The key‘s randomart image is: +---[RSA 2048]----+ | +*++= | | ..++o.+| | =.E oo| | .o.+ *.+| | S .*.o *o| | ..* o.o| | ..* o.| | .+ *.o| | .+oO*| +----[SHA256]-----+ - 傳遞公鑰給 Centos7-002(可查看Centos機器上是否生成 /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: - 安裝 inotify-tools 工具
# yum install epel-release -y
# yum install inotify-tools -y
# rpm -q inotify-tools- 利用 inotifywait 命令監控本機的 /var/www/html/目錄，如發生變化就同步到Centos7-002:/web_backup上(寫一個腳本 inotify.sh),在後臺運行此腳本(Centos7-002上需要先安裝 rsync)
[root@centos7-001 ~]# 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 $dir root@$remote_dir
done- 在本地上的/var/www/html/創建文件、目錄，刪除文件、目錄，修改文件、目錄
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
- 安裝 rsync
# yum install rsync -y- 觀察本機的 /web-back目錄
