rsync+inotify實現資料實時同步
阿新 • • 發佈:2018-11-14
主伺服器192.168.222.4 CentOS7
從伺服器192.168.222.5 CentOS6
實時同步/home/data1目錄到從伺服器
從伺服器192.168.222.5操作
# yum -y install rsync*
建立rsyncd.conf檔案
vim /etc/rsyncd.conf
uid = root #以root使用者執行rsync服務
gid = root #以root使用者執行rsync服務
use chroot = no #增加對目錄檔案軟連線的備份
max connections = 1200 #最大連線數
timeout = 800 #超時時間
pid file = /var/run/rsyncd.pid #PID存放位置
lockfile = /var/run/rsyncd.lock #鎖檔案存放位置
log file = /var/log/rsyncd.log #日誌存放位置
[synchronization] #認證模組名
path = /home/data1 #同步A伺服器的檔案路徑
ignore errors = yes #忽略無關錯誤資訊
hosts allow = 192.168.222.5 #允許訪問IP
hosts deny = * #除了從主機外拒絕所有
read only = no #允許上傳
write only = no #允許下載
list = yes #允許列出同步目錄
auth users = root #同步的使用者
secrets file = /etc/rsync.pass #存放使用者密碼的檔案
###########可以配置多個同步模組
[download]
path = /home/download
ignore errors = yes
hosts allow = 192.168.222.5
hosts deny = *
read only = no
list = yes
auth users = root
secrets file = /etc/rsync.pass
注:/etc/rsync.pass 檔案格式為username:password檔案許可權必須為600否則服務不正常,hosts allow 定義可為單獨IP也可為網段,網段格式為192.168.222.0/24也可為192.168.222.0/255.255.255.0
建立rsync.pass檔案
# echo “root:password” >> /etc/rsync.pass
# chmod 600 /etc/rsync.pass
啟動服務
# rsync --daemon –v
開機自啟動
# echo “rsync --daemon –v” >> /etc/rc.local

########如果是多個目錄同步需要起兩個sersync程序同時需要兩個啟動配置檔案
cp /usr/local/sersync/confxml.xml /usr/local/sersync/downxml.xml
vi /usr/local/sersync/downxml.xml

配置密碼檔案
echo “password” > /usr/local/sersync/user.pass
注:檔案許可權必須為600否則啟動異常
chmod 600 /usr/local/sersync/user.pass
2.4服務啟動
nohup /usr/local/sersync/sersync2 -r -d -o /usr/local/sersync/confxml.xml > /usr/local/sersync/rsync.log 2>1
#######如果是多個目錄同步需要啟動兩個程序
nohup /usr/local/sersync/sersync2 -r -d -o /usr/local/sersync/downxml.xml > /usr/local/sersync/rsync.log 2>1
-d:啟用守護程序模式
-r:在監控前,將監控目錄與遠端主機用rsync命令推送一遍
-n:指定開啟守護執行緒的數量,預設為10個
-o:指定配置檔案,預設使用confxml.xml檔案
開機啟動寫入/etc/rc.local檔案中
