建议 cp eth0 eth0:0
ifup eth0:0
修改 vim/etc/hosts

WORKING_USER = mfs
WORKING_GROUP = mfs
设置挂载点
cat >mfsexports.cfg<<EOF
#ALLOW "meta"
* . rw #启用回收站
#ALLow everything but "meta"
10.0.0.0/24 / rw,alldirs,mppall=mfs:mfs,password=111111 #设置：网段，挂载目录，权限，用户密码

yum install fuser* zlib* -y
tar zxf mfs-1.6.27-5.tar.gz
cd mfs-16.27

echo "exprt PATH=$PATH:/application/mfs/sbin:/application/mfs/bin" >>/etc/profile
tail -l /etc/profile
cp mfsmetalogger.cfg.dist mfsmetalogger.cfg
vim mfsmetalogger.cfg
MASTER_HOST = mfsmaster.etiantian.org #修改maste的 ip地址或者域名
启动
/application/mfs/sbin/mfsmetalogger start
netstat -lntup |grep mfs
netstat -lntup |grep 94
netstat -an |grep -i est
chown -R mfs /application/mfs/var/mfs
tail -f /var/log/messages
设置开机启动
echo "/application/mfs/sbin/mfsmetalogger start" >>/etc/rc.local
data安装
roupadd mfs
useradd -g mfs mfs -s /sbin/nologin
yum install fuser* zlib* -y
tar zxf mfs-1.6.27-5.tar.gz
cd mfs-16.27
./configure --prefix=/application/mfs-1.6.27 --with-default-user=mfs --with-default-group=mfs
make
make install
ln -s /application/mfs-1.6.27 /application/mfs
ll /aaplication/ |grep mfs
设置环境变量
echo "exprt PATH=$PATH:/application/mfs/sbin:/application/mfs/bin" >>/etc/profile
tail -l /etc/profile
vim mfschunkserver.cfg
MASTER_HOST = mfsmaster.etiantian.org # 修改master ip地址或者域名
修改挂载目录
vim /application/mfs/etc/mfs/mfshdd.cfg
/msfdata #可以设置多个
chown -R mfs.mfs /msfdata
启动
/application/mfs/sbin/mfschunkserver start
vim mfschunkserver.cfg
其它几台server 安装一样
安装客户端
如果客户端没有fuse 需要安装
wget http://nchc.dl.sourceforge.net/project/fuse/fuse-2.X/2.9.2/fuse-2.9.2.tar.gz
./configure
make
make install
roupadd mfs
useradd -g mfs mfs -s /sbin/nologin
yum install fuser* zlib* -y
tar zxf mfs-1.6.27-5.tar.gz
cd mfs-16.27
./configure --prefix=/application/mfs-1.6.27 --with-default-user=mfs --with-default-group=mfs
make
make install
ln -s /application/mfs-1.6.27 /application/mfs
ll /aaplication/ |grep mfs
方法（1）设置开机自动加载fuse到内核
echo "/modprobe fuse" >/etc/sysconfig/modules/fuse.modules
chmod 755 /etc/sysconfig/modules/fuse.modules
方法（2）设置开机自动加载fuse到内核
echo "modprobe fuse" >>/etc/ec.modules
chmod 755 /etc/rc.modules
挂载
/application/mfs/bin/mfsmount /mnt/mfs -H mfsmster.etiantian.org -o mfspassword=111111
搭建完成
随便创建几个文件 分别在master和backup查看日志
cat /application/mfs/var/mfs/changelog_ml
查看文件命令
mfsfileinfo 1
设置副本：为3份
mfssetgoal -r 3 a1
查看数量
mfsfileinfo al/10
测试
创建文件
dd if=/dev/zero of=/mnt/mfs/test/10m.img bs=1M count=10
mfsfileinfo test/10m.img
查看删除文件时间
mfsgettrashtime 10m.img
设置文件删除时间
mfssettrashtime -r 1200 /a2
客户端挂载回收站
mfsmaster.etiantian.org -m /mnt/mfs-trash/
还原文件
移动删除的文件到 undel下即可
mv 0000002\|a2\|oldboy.txt undel/
备份master与master恢复1
需要备份下面两个文件
/application/mfs/var/
/application/mfs//etc/
脚本
while true
do
cd /application/mfs
rsyrc -azv var /opt/ >/dev/null 2>&1
rsyrc -azv etc /opt/ >/dev/null 2>&1
usleep 500000
done
sh -x bakmeta.sh
sh bakmeta.sh &
恢复master
新安装机器用上面备份的文件直接覆盖即可
mfsmetarestore -a
/application/mfs/sbin/mfsmaster start
客户端需要重新挂载
umount /mnt/mfs
/application/mfs/bin/mfsmount /mnt/mfs -H mfsmster.etiantian.org -o mfspassword=111111
备份master与master恢复2
首先该ip地址
建议 cp eth0 eth0:0
ifup eth0:0
修改 vim/etc/hosts
把上面备份好的rsyrc -azv etc /opt/ 拷贝到 /application/mfs 下面
mfsmetalogger -s
cd /application/mfs
mfsmetalogger -m metadata_ml.mfs.back* -o metadata.mfs changelog_ml*
mfsmaster start
netstat -lntup |grep 94
mfscgiserv start
解决单点故障
利用keepalived+inotify 实现 mfs master的高可用
