要求rsync >= 3.1
rsync --version
systemctl status rsyncd
1.安装lsyncd
yum install -y lsyncd
lsyncd --version
2.创建日志文件
mkdir /var/log/lsyncd
touch /var/log/lsyncd/lsyncd.{log,status}
3.创建配置文件
mkdir -p /etc/lsyncd
vim /etc/lsyncd.conf
4.配置文件写入以下内容:
settings {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/log/lsyncd/lsyncd.status",
pidfile = "/var/run/lsyncd.pid",
statusInterval = 1,
nodaemon = false,
maxProcesses = 1,
maxDelays = 1,
}
#本地同步
sync {
default.rsync,
source = "/data/source",
target = "/data/target",
}
#rsync+ssh远程目录同步,需要免key登录
sync {
default.rsyncssh,
source="/data/source",
delete = true,
host="root@192.168.15.6",
targetdir="/data/target",
-- 忽略文件路径规则,可用table也可用外部配置文件
-- excludeFrom = "/etc/lsyncd_exclude.lst",
exclude={
".txt" --需排除的文件
},
rsync = {
binary = "/usr/bin/rsync", --需先安装好rsync
archive = true, --归档
compress = false, --压缩
owner = true, --属主
perms = true, --权限
whole_file = false
},
ssh = {
port = 22
}
}
#rsync-daemon模式,需要配置好rsync的服务端
sync {
default.rsync,
source = "/data/source",
target = "rsync_user@192.168.15.6::backup",
exclude = { ".bak*" },
delete = true,
delay = 30,
init = true,
rsync = {
binary = "/usr/bin/rsync",
archive = true,
compress = true,
verbose = true,
perms = true,
password_file = "/etc/rsync.password",
_extra = {"--bwlimit=200"} --bwlimit 限速,单位kb/s,
}
}
5.启动lsyncd服务
lsyncd -nodaemon /etc/lsyncd.conf
systemctl restart lsyncd
systemctl enable lsyncd
6.rsync-daemon模式
#lsyncd端配置
vim /etc/rsync.password
echo "1234567" > /etc/rsync.password
chmod 600 /etc/rsync.password
#rsync服务端配置
安装rsync
vim /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
strict modes = no
max connections = 100
charset=utf8
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
hosts allow = 192.168.15.20
hosts deny = *
[backup]
path = /data/target/
read only = no
write only = no
list = no
exclude = .svn/
dont compress = *.gz *.tgz *.zip *.z *.bz2 *.tbz
auth users = rsync_user
secrets file = /etc/rsync/rsync.pass
echo 'rsync_user:123456'>/etc/rsync/rsync.pass
chmod 600 /etc/rsync/rsync.pass
#rsync用法
rsync -auv --password-file=/etc/rsync.password --delete /data/source/ rsync_user@192.168.15.6::backup
#lsyncd delete -- 用法如下
