web备份方案

发表于

一、服务器环境

    192.168.100.230 web服务器
    192.168.100.20  备份服务器 （rsync服务端）

二、备份服务器安装 rsync 服务端

rpm -qa|grep rsync    //检查是否安装 rsync

yum install -y rsync

vim /etc/rsyncd.conf   //编辑rsyncd服务

rsyncd.conf配置文件如下

#rsyncd.conf start
uid = rsync                                
gid = rsync
use chroot=no
max connections=200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log
ignore errors
read only = false
list = false 
hosts allow = 172.16.1.0/24
#hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password
fake super = yes
[backup]
comment = "backup dir by oldboy"
path = /home/backup  
#备份的目录
创建rsync 服务管理用户
useradd -s /sbin/nologin -M rsync

创建数据备份存储目录
chown -R rsyn.rsync /home/backup

创建认证用户密码文件
echo "rsync_backup:admin.123!@#$"  >/etc/rsync.password
chmod 600 /etc/rsync.password

启动rsync服务
systemctl start rsyncd

三、配置web 服务器端（192.168.100.230）

    确认 rsync是否安装
        rpm -qa|grep rsync
    
    建立认证文件
    
        echo "密码字符串（与rsync一致）"  >/etc/rsync.password
        chmod 600 /etc/rsync.password
    
    web01主机数据传输到backup主机测试测试传输
    
        Push: rsync [OPTION...] SRC... [USER@]HOST::DEST
        交互式：rsync -avz /etc/hosts  rsync_backup@172.16.1.41::backup
        非交互式：rsync -avz /etc/hosts  rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password
        
        
    shell 脚本

objectFilename=('文件夹名称');
sourcePath='/apps/web/';
for(( i=0;i<${#objectFilename[@]};i++)) 
do 
    tar zcf /home/backup/web/source/${objectFilename[i]}-$(date +%Y-%m-%d).tar.gz -C ${sourcePath} ${objectFilename[i]}; 
    rsync -avz /home/backup/web/source/  rsync_backup@192.168.100.20::backup --password-file=/etc/rsync.password
    rm -rf /home/backup/web/source/${objectFilename[i]}-$(date +%Y-%m-%d).tar.gz
done;

四、注意事项

特殊情况 总是提示权限问题修改 服务端

    uid = root                                
    gid = root
    fake super = no


脚本备份大文件有问题
