3，开始安装rsync软件
在192.168.0.51，192.168.0.50，192.168.0.53按照如下顺序安装rsync软件
3.1，查看线上rsync版本
通过rsync -h找到查看帮助，找到 --version参数。
[root@localhost ~]# rsync --version
rsync version 3.0.6 protocol version 30

3.2，下载
wget
3.3，编译安装
# 解压缩
[root@localhost root]# tar -xvf rsync-3.0.6.tar.gz
[root@localhost rsync-3.0.6]# cd rsync-3.0.6
# 通过./configure --help查看编译参数，这里选取--prefix参数
[root@localhost rsync-3.0.6]# ./configure --prefix=/usr/local/rsync-3.0.6/

[root@localhost rsync-3.0.6]#
[root@localhost rsync-3.0.6]# make install
mkdir -p /usr/local/rsync-3.0.6/bin
/usr/bin/install -c -m 755 rsync /usr/local/rsync-3.0.6/bin
mkdir -p /usr/local/rsync-3.0.6/share/man/man1
mkdir -p /usr/local/rsync-3.0.6/share/man/man5
if test -f rsync.1; then /usr/bin/install -c -m 644 rsync.1 /usr/local/rsync-3.0.6/share/man/man1; fi
if test -f rsyncd.conf.5; then /usr/bin/install -c -m 644 rsyncd.conf.5 /usr/local/rsync-3.0.6/share/man/man5; fi
[root@localhost rsync-3.0.6]#
3.3，check命令
[root@localhost ~]# rsync -h
rsync version 3.0.6 protocol version 30

看来已经安装好，命令可以直接使用。
3.4，配置rsyncd.conf启动参数文件
[root@localhost ~]# vim /etc/rsyncd.conf
uid=nginx #用户id名称
gid=nginx #用户所属组ID
use chroot=no
max connections=10
strict modes=yes
port=873
address=192.168.0.50 #本机地址，3台IP地址都填写自己的IP地址
#ignore erros
read only=no
list=no
auth users=nginx
secrets file=/etc/rsync.pas #密码认证文件地址
hosts allow=192.168.0.51,192.168.0.53 #允许rsync同步的ip地址，除了本机地址的其它2个ip地址。
pid file=/home/nginx/rsync/rsyncd.pid
lock file=/home/nginx/rsync/rsync.lock
log file=/home/nginx/rsync/rsyncd.log
[web]
path=/usr/local/nginx/ # 这里的web就是rsync同步的参数名字，path就是同步的目录
comment=mirror for web
3.5，添加认证文件
# 创建认证文件
[root@localhost ~]# vim /etc/rsync.pas
nginxpasspd #密码
nginx:nginxpasswd #用户名：密码
【PS】：不这样设置两行就会用户验证失败。
# 赋予权限
[root@localhost ~]# chmod 600 /etc/rsync.pas
3.6，创建目录并赋予权限
# 创建目录
mkdir -p /usr/local/nginx
mkdir -p /home/nginx/rsync
mkdir -p /usr/local/nginx/web
# 赋予权限
chown -R nginx.nginx /usr/local/nginx /home/nginx/rsync/ /usr/local/nginx/web
3.7，启动rsync服务
[root@localhost ~]# rsync --daemon --config=/etc/rsyncd.conf
[root@localhost ~]# ps -eaf|grep rsync
root 1387 1 0 Jun28 ? 00:00:00 rsync --daemon --config=/etc/rsyncd.conf
root 3201 3136 0 00:50 pts/0 00:00:00 grep rsync
[root@localhost ~]#
启动成功
3.8，测试rsync功能
一些调试报错经历：
[root@localhost ]#
rsync -vzrt --delete --progress --itemize-changes --exclude-from=/home/nginx/exclude_fastdfs.txt /data/fastdfs/data nginx@192.168.0.53::web --password-file=/etc/rsync.pas
password file must not be other-accessible
continuing without password file
Password:
@ERROR: auth failed on module web
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
[root@localhost ]#
说明：这是因为/etc/rsync.pas的权限不对，应该设置为600。如：chmod 600 /etc/rsync.pas
[root@localhost inotify-tools-3.14]#
rsync -vzrt --delete --progress --itemize-changes --exclude-from=/home/nginx/exclude_fastdfs.txt /data/fastdfs/data nginx@192.168.0.53::fastdfs --password-file=/home/nginx/rsync.pas
@ERROR: auth failed on module fastdfs
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
[root@localhost inotify-tools-3.14]# ll
去查看192.168.0.53的log信息
[root@localhost inotify-tools-3.14]# tail -f /home/nginx/rsync/rsyncd.log
2014/06/28 17:24:14 [19031] auth failed on module web from unknown (192.168.0.50): missing secret for user "nginx"

2014/06/28 17:28:21 [19198] connect from UNKNOWN (192.168.0.50)
2014/06/28 17:28:21 [19198] auth failed on module web from unknown (192.168.0.50): missing secret for user "nginx"
2014/06/28 17:28:48 [19488] name lookup failed for 192.168.0.50: Name or service not known
去192.168.0.53上面修改认证文件
[root@localhost data]# vim /etc/rsync.pas
nginxpasswd
nginx: nginxpasswd
将原来只有一行密码的改成如此2行，就好使了，能使用rsync功能了。
测试验证，在192.168.0.50的空目录下，建立测试文件 1.txt，2.txt
[root@localhost data]# cd /usr/local/nginx/web
[root@localhost web]# ll
总用量 0
[root@localhost web]# vim 1.txt
[root@localhost web]# vim 2.txt
[root@localhost web]# mkdir test
[root@localhost web]# vim ./test/3.txt
[root@localhost web]# ll /usr/local/nginx/web
总用量 12
-rw-r--r--. 1 nginx nginx 6 6月 28 19:18 1.txt
-rw-r--r--. 1 nginx nginx 6 6月 28 19:18 2.txt
drwxr-xr-x. 2 nginx nginx 4096 6月 28 19:22 test
[root@localhost web]#
在rsync同步之前，先去53上面check下目标目录，为空目录，如下所示：
[root@localhost web]# ll /usr/local/nginx/web
总用量 0
[root@localhost web]#
在192.168.0.50上执行rsync命令，同步目录
[root@localhost web]# /usr/bin/rsync -auzv --progress --delete /usr/local/nginx/web nginx@192.168.0.53::webroot --password-file=/etc/rsync.pas

再去192.168.0.53上check下，看到文件已经同步过来，测试成功，如下所示：
[root@localhost web]# ll
总用量 12
-rw-r--r--. 1 nginx nginx 6 6月 28 19:18 1.txt
