####主機：
backup nfs01
####系統環境：
[root@backup ~]# cat /etc/redhat-release CentOS release 6.8 (Final) [root@backup ~]# uname -r 2.6.32-642.el6.x86_64 [root@backup ~]# /etc/init.d/iptables status iptables: Firewall is not running. [root@backup ~]# getenforce Disabled ####安裝包 yum install keepalived -y

####修改backup rsyncd.conf配置文件
######rsync_config_______________start ##rsyncd.conf start## uid = www gid = www use chroot = no max connections = 200 timeout = 300 pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log file = /var/log/rsyncd.log ignore errors read only = false list = false hosts allow = 172.16.1.0/24 #hosts deny = 0.0.0.0/32 auth users = rsync_backup secrets file = /etc/rsync.password [backup] path = /backup/ [nfsbackup] path = /nfsbackup/ [web01backup] path = /web01backup/ [data] path = /data #rsync_config_______________end
####修改rsync匿名用戶為www uid為888，添加一個模塊/data
--------------------------------------------------
--------------------------------------------------
####添加用戶
useradd -s /sbin/nologin -M -u888 www id www mkdir /data chown -R www.www /web01backup /nfsbackup /backup /data
####修改nfs01的sersync配置文件，將rsync的模塊改為data
<?xml version="1.0" encoding="ISO-8859-1"?> <head version="2.5"> <host hostip="localhost" port="8008"></host> <debug start="false"/> <fileSystem xfs="false"/> <filter start="false"> <exclude expression="(.*)\.svn"></exclude> <exclude expression="(.*)\.gz"></exclude> <exclude expression="^info/*"></exclude> <exclude expression="^static/*"></exclude> </filter> <inotify> <delete start="true"/> <createFolder start="true"/> <createFile start="false"/> <closeWrite start="true"/> <moveFrom start="true"/> <moveTo start="true"/> <attrib start="false"/> <modify start="false"/> </inotify> <sersync> <localpath watch="/data"> <remote ip="172.16.1.41" name="data"/> <!--<remote ip="192.168.8.39" name="tongbu"/>--> <!--<remote ip="192.168.8.40" name="tongbu"/>--> </localpath> <rsync> <commonParams params="-az --delete"/> <auth start="true" users="rsync_backup" passwordfile="/etc/rsync.password"/> <userDefinedPort start="false" port="874"/><!-- port=874 --> <timeout start="false" time="100"/><!-- timeout=100 --> <ssh start="false"/> </rsync> <failLog path="/var/log/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins execute once--> <crontab start="false" schedule="600"><!--600mins--> <crontabfilter start="false"> <exclude expression="*.php"></exclude> <exclude expression="info/*"></exclude> </crontabfilter> </crontab> <plugin start="false" name="command"/> </sersync> <plugin name="command"> <param prefix="/bin/sh" suffix="" ignoreError="true"/> <!--prefix /opt/tongbu/mmm.sh suffix--> <filter start="false"> <include expression="(.*)\.php"/> <include expression="(.*)\.sh"/> </filter> </plugin> <plugin name="socket"> <localpath watch="/opt/tongbu"> <deshost ip="192.168.138.20" port="8009"/> </localpath> </plugin> <plugin name="refreshCDN"> <localpath watch="/data0/htdocs/cms.xoyo.com/site/"> <cdninfo domainname="ccms.chinacache.com" port="80" username="xxxx" passwd="xxxx"/> <sendurl base="http://pic.xoyo.com/cms"/> <regexurl regex="false" match="cms.xoyo.com/site([/a-zA-Z0-9]*).xoyo.com/images"/> </localpath> </plugin> </head>

####在backup啟動rpcbind nfs服務，共用/data目錄
[root@backup data]# cat /etc/exports #share /data by oldboy for bingbing at 20160425 /data/www 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888) /data/bbs 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888) /data/blog 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
####啟動服務
chkconfig rpcbind on
chkconfig nfs on
####將web服務的掛載ip改為172.16.1.3
umount -lf /application/nginx-1.10.2/html/www/uploads umount -lf /application/nginx-1.10.2/html/bbs umount -lf /application/nginx-1.10.2/html/blog/wp-content
####NFS客戶端內核優化
cat >>/etc/sysctl.conf<<EOF net.core.wmem_default = 8388608 net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 EOF sysctl -p
####客戶端掛載優化
mount -t nfs -o nosuid,noexec,nodev,noatime,nodiratime,rsize=131072,wsize=131072 172.16.1.3:/data/www /application/nginx-1.10.2/html/www/uploads mount -t nfs -o nosuid,noexec,nodev,noatime,nodiratime,rsize=131072,wsize=131072 172.16.1.3:/data/bbs /application/nginx-1.10.2/html/bbs mount -t nfs -o nosuid,noexec,nodev,noatime,nodiratime,rsize=131072,wsize=131072 172.16.1.3:/data/blog /application/nginx-1.10.2/html/blog/wp-content
####解決nfs服務停止keepalived不跳到backup的問題，編寫腳本
[root@m01 storage]# cat check_nfs.sh #!/bin/bash if [ `showmount -e localhost|wc -l` -lt 4 ];then /etc/init.d/keepalived stop fi
####啟動服務，加入開機自啟動
/etc/init.d/keepalived start
chkconfig keepalived on
