爲了網站的隨時可以遷移或者負載均衡，必須保證web根目錄的一致性，所以得實時同步
下面是我模擬遷移前的一個web同步：
用於遷移前的數據同步，主要利用rsync+lsync
客戶端：192.168.1.135 （網站備份數據）
服務器：192.168.1.136 （網站源數據）
客戶端安裝rsync：
yum install -y rsync xinetd
爲rsync添加配置文件
vi /etc/rsyncd.conf
[root@cm root]# cat /etc/rsyncd.conf
uid = nobody //啓動服務的用戶
gid = nobody //啓動服務的組
use chroot = yes //限制籠環境
max connections = 10 //最大連接數
timeout = 300 //超時時間
strict modes = yes
pid file = /var/run/rsync/rsyncd.pid
#lock file = /var/run/rsync/rsyncd.lock
log file = /var/log/rsync/rsyncd.log
[data] //模塊
#path =/usr/local/nginx-1.6.3/html/home/paixian/root
path = /usr/local/nginx/html/home/paixian/root //模塊路徑
ignore errors = yes //忽略錯誤
read only = no //是否只讀
write only = no //是否只寫
hosts allow = * //訪問限制
#hosts deny =
list = false
uid = root
gid = root
auth users = min //認證用戶
secrets file = /etc/rsyncd.passwd //認證密碼文件
配置認證文件
vi /etc/rsyncd.passwd
[root@cm root]# cat /etc/rsyncd.passwd
min:min //用戶：密碼
添加權限
chmod 600 /etc/rsyncd.passwd //授權
啓動服務
service xinetd restart
檢測服務是否啓動
ss -tulnp|grep 873
服務器安裝rsync
yum install -y rsync xinetd
添加認證文件
vi /etc/rsyncd.passwd
[root@min bin]# cat /etc/rsyncd.passwd
min
授權認證文件
chmod 600 /etc/rsyncd.passwd
測試客戶端的rsync
rsync --list-only--password-file=/etc/rsyncd.passwd [email protected]::data
[root@min bin]# rsync --list-only --password-file=/etc/[email protected]::data

安裝lsyncd
cd /usr/local
unzip lsyncd-master.zip //解壓
cd lsyncd-master
cmake-DCMAKE_INSTALL_PREFIX=/usr/local/lsyncd-2.1.5 //編譯指定路徑
make && make install
添加配置文件
cd /usr/local/lsyncd-2.1.5
mkdir etc var //創建配置文件和日誌文件
vi etc/lsyncd.conf //添加配置文件
[root@min root]# cat/usr/local/lsyncd-2.1.5/etc/lsyncd.conf
settings {
logfile ="/usr/local/lsyncd-2.1.5/var/lsyncd.log",
statusFile ="/usr/local/lsyncd-2.1.5/var/lsyncd.status",
inotifyMode ="CloseWrite",
maxProcesses = 7,
-- nodaemon =true,
}
sync {
default.rsync,
source ="/usr/local/nginx-1.6.3/html/home/root", //源路徑
target ="[email protected]::data", //目標路徑
delete="running",
exclude = {".*",".tmp"}, //排除哪些文件
delay = 0, //推遲多少秒，一起發送
init = false,
rsync ={
binary = "/usr/bin/rsync",
archive = true,
compress = true,
verbose = true,
password_file = "/etc/rsyncd.passwd",
_extra ={"--bwlimit=200"}
}
}
啓動lrsyncd
cd bin/
./lsyncd -log Exec/usr/local/lsyncd-2.1.5/etc/lsyncd.conf
