rsync+lsyncd实现实时同步

为了网站的随时可以迁移或者负载均衡，必须保证web根目录的一致性，所以得实时同步
下面是我模拟迁移前的一个web同步：
用于迁移前的数据同步，主要利用rsync+lsync
客户端：192.168.1.135 （网站备份数据）
服务器：192.168.1.136 （网站源数据）
客户端安装rsync：
yum install -y rsync xinetd

为rsync添加配置文件
vi /etc/rsyncd.conf
[root@cm root]# cat /etc/rsyncd.conf
uid = nobody //启动服务的用户
gid = nobody //启动服务的组
use chroot = yes //限制笼环境
max connections = 10 //最大连接数
timeout = 300 //超时时间
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] //模块
#path =/usr/local/nginx-1.6.3/html/home/paixian/root
path = /usr/local/nginx/html/home/paixian/root //模块路径
ignore errors = yes //忽略错误
read only = no //是否只读
write only = no //是否只写
hosts allow = * //访问限制
#hosts deny =
list = false
uid = root
gid = root
auth users = min //认证用户
secrets file = /etc/rsyncd.passwd //认证密码文件

配置认证文件
vi /etc/rsyncd.passwd
[root@cm root]# cat /etc/rsyncd.passwd
min:min //用户：密码
添加权限
chmod 600 /etc/rsyncd.passwd //授权
启动服务
service xinetd restart
检测服务是否启动
ss -tulnp|grep 873

服务器安装rsync
yum install -y rsync xinetd
添加认证文件
vi /etc/rsyncd.passwd
[root@min bin]# cat /etc/rsyncd.passwd
min
授权认证文件
chmod 600 /etc/rsyncd.passwd
测试客户端的rsync
rsync --list-only--password-file=/etc/rsyncd.passwd min@192.168.1.135::data
[root@min bin]# rsync --list-only --password-file=/etc/rsyncd.passwdmin@192.168.1.135::data

安装lsyncd
cd /usr/local
unzip lsyncd-master.zip //解压
cd lsyncd-master
cmake-DCMAKE_INSTALL_PREFIX=/usr/local/lsyncd-2.1.5 //编译指定路径
make && make install
添加配置文件
cd /usr/local/lsyncd-2.1.5
mkdir etc var //创建配置文件和日志文件
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", //源路径
target ="min@192.168.1.135::data", //目标路径
delete="running",
exclude = {".*",".tmp"}, //排除哪些文件
delay = 0, //推迟多少秒，一起发送
init = false,
rsync ={
binary = "/usr/bin/rsync",
archive = true,
compress = true,
verbose = true,
password_file = "/etc/rsyncd.passwd",
_extra ={"--bwlimit=200"}
}
}
启动lrsyncd
cd bin/
./lsyncd -log Exec/usr/local/lsyncd-2.1.5/etc/lsyncd.conf
