nfs服务端 (nfs)

#1.安装服务
[Thu Jul 08 17:06:06 root@nfs ~]
 # yum install -y nfs-utils
 
#2.修改配置文件
[Thu Jul 08 17:14:01 root@nfs ~]
 # vim /etc/exports
/data/data_gx 172.16.1.0/24(rw,sync,all_squash,anonuid=666,anongid=666)

#3.创建共享目录
[Thu Jul 08 17:15:24 root@nfs ~]
 # mkdir -p /data/data_gx

#4.创建统一用户 wkhs 并且指定其uiD和gid都是666
[Thu Jul 08 17:31:42 root@nfs ~]
 # groupadd -g 666 wkhs
# useradd wkhs -u 666 -g 666 -s /sbin/nologin -M
[Thu Jul 08 17:37:25 root@nfs ~]
 # id wkhs
uid=666(wkhs) gid=666(wkhs) groups=666(wkhs)

给共享目录授权 
Thu Jul 08 18:40:25 root@nfs ~]
 # chown wkhs:wkhs /data/data_gx/


#5.启动服务
[Thu Jul 08 17:37:53 root@nfs ~]
 # systemctl start nfs-server

# 6.将nfs服务加入开机自启
[Thu Jul 08 17:39:59 root@nfs ~]
 # systemctl enable nfs-server
 
 # 7.检查进程
Thu Jul 08 17:40:28 root@nfs ~]
 #  ps -ef|grep [n]fs
root       7217      2  0 17:39 ?        00:00:00 [nfsd4_callbacks]
root       7223      2  0 17:39 ?        00:00:00 [nfsd]
root       7224      2  0 17:39 ?        00:00:00 [nfsd]
root       7225      2  0 17:39 ?        00:00:00 [nfsd]
root       7226      2  0 17:39 ?        00:00:00 [nfsd]
root       7227      2  0 17:39 ?        00:00:00 [nfsd]
root       7228      2  0 17:39 ?        00:00:00 [nfsd]
root       7229      2  0 17:39 ?        00:00:00 [nfsd]
root       7230      2  0 17:39 ?        00:00:00 [nfsd]

# 8.检查rpcbind端口号
[Thu Jul 08 17:41:06 root@nfs ~]
 # netstat -lntup|grep 111
tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN      5706/rpcbind        
tcp6       0      0 :::111                  :::*                    LISTEN      5706/rpcbind        
udp        0      0 0.0.0.0:111             0.0.0.0:*                           5706/rpcbind        
udp6       0      0 :::111                  :::*                                5706/rpcbind

nfs客户端(web01 web02)

# 1.先安装nfs-utils
[Fri Jul 09 00:52:30 root@web01 ~]
 # yum install -y nfs-utils
[Fri Jul 09 00:52:22 root@web02 ~]
 # yum install -y nfs-utils
 
# 2.查看挂载点
[Thu Jul 08 17:44:24 root@web01 ~]
 # showmount -e 172.16.1.31
Export list for 172.16.1.31:
/data/data_gx 172.16.1.0/24

# 3.创建一个用户上传数据的目录
Thu Jul 08 17:45:56 root@web01 ~]
 # mkdir -p /wk/wk_pic

# 4.挂载远端的目录
Thu Jul 08 17:47:52 root@web01 ~]
 # mount -t nfs 172.16.1.31:/data/data_gx /wk/wk_pic
 
 #5.查看挂载
[Thu Jul 08 17:49:55 root@web01 ~]
 # df -h
Filesystem                 Size  Used Avail Use% Mounted on
/dev/sda3                   19G  1.6G   17G   9% /

rsync服务端(backup)

#1.安装rsync
[Thu Jul 08 16:52:31 root@backup ~]
 # yum -y install rsync
 
 #2.修改配置文件
[Thu Jul 08 17:55:12 root@backup ~]
 # vim /etc/rsyncd.conf 
uid = wkhs
gid = wkhs
port = 873
fake super = yes
use chroot = no
max connections = 200
timeout = 600
ignore errors
read only = false
list = false
auth users = wk_nb
secrets file = /etc/wk.pass
log file = /var/log/rsyncd.log
#####################################
[mm]
comment = welcome to oldboyedu backup!
path = /boy/mm

# 3.创建服务启动的用户
[Thu Jul 08 18:02:33 root@backup ~]
 # useradd wkhs -s /sbin/nologin -M
 
# 4.创建虚拟用户的密码文件
密码文件的格式
用户名:密码
[Thu Jul 08 18:04:06 root@backup ~]
 # echo 'wk_nb:123' > /etc/wk.pass
 [Thu Jul 08 18:06:25 root@backup ~]
 # cat /etc/wk.pass
wk_nb:123

# 5.rsync要求密码文件的权限必须是600
[Thu Jul 08 18:06:39 root@backup ~]
 # chmod 600 /etc/wk.pass
 
# 6.创建一个同步的路径
[Thu Jul 08 18:08:09 root@backup ~]
 # mkdir -p /boy/mm
 
# 7.修改同步路径的属主和属组
[Thu Jul 08 18:09:22 root@backup ~]
 # chown wkhs:wkhs /boy/mm
 
# 8.启动rsync服务
[Thu Jul 08 18:10:37 root@backup ~]
 # systemctl start rsyncd
 
 
# 9.加入开机自启
Thu Jul 08 18:11:21 root@backup ~]
 # systemctl enable rsyncd
 
#10..验证服务启动(进程,端口)
# ps -ef|grep [r]sync
root       7236      1  0 18:11 ?        00:00:00 /usr/bin/rsync --daemon --no-detach
[Thu Jul 08 18:13:48 root@backup ~]
 # netstat -lntup|grep 873
tcp        0      0 0.0.0.0:873             0.0.0.0:*               LISTEN      7236/rsync          
tcp6       0      0 :::873                  :::*                    LISTEN      7236/rsync

rsync客户端(nfs)

#1.安装服务
[Thu Jul 08 17:41:59 root@nfs ~]
 # yum -y install rsync
 
 记住所有客户端和服务端要提前把防火墙关闭 还有关闭selinux
[Thu Jul 08 18:49:32 root@nfs ~]
 # setenforce 0
 [Thu Jul 08 18:49:32 root@nfs ~]
 # vim /etc/selinux/config 
SELINUX=disabied
[Thu Jul 08 18:52:05 root@nfs ~]
 # systemctl stop firewalld
[Thu Jul 08 18:52:05 root@nfs ~]
 # systemctl disable firewalld

 免交互
#1 创建密码文件(客户端的密码文件只写密码不写用户)
[Thu Jul 08 18:19:52 root@nfs ~]
 # echo '123' > /tmp/rsync.pass
 [Thu Jul 08 18:20:01 root@nfs ~]
 #  chmod 600 /tmp/rsync.pass
 [Thu Jul 08 18:46:44 root@nfs ~]
 # rsync -avz /data/data_gx/ wk_nb@172.16.1.41::mm --password-file=/tmp/rsync.pass
 
 无差异同步
[Thu Jul 08 18:52:05 root@nfs ~]
 # rsync -avz --delete /data/data_gx wk_nb@172.16.1.41::mm
 

部署sersync(客户端nfs)

# 1.安装sersync的依赖包
[Thu Jul 08 18:55:12 root@nfs ~]
 # yum install rsync inotify-tools -y
 
# 2.创建存放源码包的目录
[Thu Jul 08 18:58:29 root@nfs ~]
 #  mkdir /source_code
 
# 3.获取sersync的安装包
[Thu Jul 08 19:01:01 root@nfs ~]
 # wget http://test.driverzeng.com/other/sersync2.5.4_64bit_binary_stable_final.tar.gz
 
 # 4.绿色软件解压即用
[Thu Jul 08 19:09:34 root@nfs ~]
 # tar xf sersync2.5.4_64bit_binary_stable_final.tar.gz
 
 # 5.创建服务安装目录
[Thu Jul 08 19:09:45 root@nfs ~]
 # mkdir /app
 
 # 6.将软件安装在app目录下
[Thu Jul 08 19:11:33 root@nfs ~]
 # mv GNU-Linux-x86 /app/sersync
 
 # 7.查看程序相关文件
[Thu Jul 08 19:13:14 root@nfs /app/sersync]
 # ll
total 1772
-rwxr-xr-x. 1 root root    2214 Oct 26  2011 confxml.xml
-rwxr-xr-x. 1 root root 1810128 Oct 26  2011 sersync2

# 8.修改配置文件
修改inotify相关的配置
[Thu Jul 08 19:13:16 root@nfs /app/sersync]
 #  vim confxml.xml
 
<inotify>
        <delete start="true"/>
        <createFolder start="true"/>
        <createFile start="true"/>
        <closeWrite start="true"/>
        <moveFrom start="true"/>
        <moveTo start="true"/>
        <attrib start="true"/>
        <modify start="true"/>
    </inotify>
        <closeWrite start="true"/>
        <moveFrom start="true"/>
        <moveTo start="true"/>
        <attrib start="true"/>
        <modify start="true"/>
<sersync>
        <localpath watch="/data/data_gx">
            <remote ip="172.16.1.41" name="mm"/>
            <!--<remote ip="192.168.8.39" name="tongbu"/>-->
            <!--<remote ip="192.168.8.40" name="tongbu"/>-->
        </localpath>
        <rsync>
            <commonParams params="-az"/>
            <auth start="true" users="wk_nb" passwordfile="/tmp/rsync.pass"/>
            <userDefinedPort start="false" port="874"/><!-- port=874 -->
            <timeout start="false" time="100"/><!-- timeout=100 -->
            <ssh start="false"/>
            
 # 9.给密码文件授权
 因为配置文件里的passwordfile="/tmp/rsync.pass"/> 中的存放密码的目录 在前期免交互的时候已经创建过了 所以修改过之后  直接在授权就行了
[Thu Jul 08 19:30:00 root@nfs /app/sersync]
 # chmod 600 /tmp/rsync.pass
 
 #10.使用systemd管理没有启动脚本的服务
 [Thu Jul 08 20:01:34 root@nfs /app/sersync]
 # vim /usr/lib/systemd/system/sersyncd.service
[Unit]
# 描述
Description=This is sersync start service
## 描述
After=xxx
[Service]
## 后台运行
Type=forking
ExecStart=/app/sersync/sersync2 -rdo /app/sersync/confxml.xml
ExecStop=kill -3 `ps -ef|grep [s]ersync|awk '{print $2}'`
ExecReload=kill -1 `ps -ef|grep [s]ersync|awk '{print $2}'`
PrivateTmp=true
[Install]
WantedBy=multi-user.target

# 记住做完之后先杀一下之前开启的进程 然后再重新开启就可以了
