mfs文件系统配置安装

安装依赖包
yum -y install gcc gcc-c++ glib fuse zlib zlib-devel pkgconfig fuse-devel make

下载mfs
wget http://jaist.dl.sourceforge.net/project/moosefs/moosefs/1.6.26/mfs-1.6.26.tar.gz

创建mfs用户
useradd mfs -s /sbin/nologin
解压源码配置，编译安装。
tar -zxvf mfs-1.6.25.tar.gz && cd mfs-1.6.25 && ./configure --prefix=/usr/local/mfs --with-default-user=mfs --with-default-group=mfs ; make ; make install

useradd mfs -s /sbin/nologin && cd /usr/src/ && tar -zxvf mfs-1.6.25-1.tar.gz && cd mfs-1.6.25 && ./configure --prefix=/usr/local/mfs --with-default-user=mfs --with-default-group=mfs; make; make install
配置元数据服务器
cd /usr/local/mfs/etc/ && mkdir backup && mv *.dist backup/ && cp backup/mfsmaster.cfg.dist ./mfsmaster.cfg && cp backup/mfsexports.cfg.dist ./mfsexports.cfg

mkdir /opt/mfs && cp /usr/local/mfs/var/mfs/metadata.mfs.empty /opt/mfs/metadata.mfs && vi /usr/local/mfs/etc/mfsmaster.cfg

启动元数据服务器
[root@os-M etc]# /usr/local/mfs/sbin/mfsmaster start
working directory: /opt/mfs
lockfile created and locked

if it is not fresh installation then you have to restart all active mounts !!!

master <-> metaloggers module: listen on *:9419

配置chunkserver
[root@os-1 mfs-1.6.25]# cd /usr/local/mfs/etc/
[root@os-1 etc]# mkdir backup
[root@os-1 etc]# mv *.dist backup/
[root@os-1 etc]# ls
backup
[root@os-1 etc]# cp backup/mfschunkserver.cfg.dist ./mfschunkserver.cfg
[root@os-1 etc]# vi mfschunkserver.cfg
[root@os-1 etc]# cp backup/mfshdd.cfg.dist ./mfshdd.cfg
[root@os-1 etc]# vi mfshdd.cfg
[root@os-1 etc]# cat mfschunkserver.cfg |grep -v ^$|grep -v ^#
 MASTER_HOST = 192.168.10.20
 MASTER_PORT = 9420
[root@os-1 etc]# cat mfshdd.cfg
# mount points of HDD drives
#
#/mnt/hd1
/home/mfs
#etc.
[root@os-1 etc]#
#######
cd /usr/local/mfs/etc/ && mkdir backup && mv *.dist backup/ && cp backup/mfschunkserver.cfg.dist ./mfschunkserver.cfg && cp backup/mfshdd.cfg.dist ./mfshdd.cfg && echo "/home/mfs" >> ./mfshdd.cfg && /usr/local/mfs/sbin/mfschunkserver start
#######
启动chunkserver
[root@os-1 etc]# /usr/local/mfs/sbin/mfschunkserver start
working directory: /usr/local/mfs/var/mfs
lockfile created and locked
initializing mfschunkserver modules ...
hdd space manager: scanning folder /home/mfs/ ...
hdd space manager: scanning complete
hdd space manager: /home/mfs/: 0 chunks found
hdd space manager: scanning complete
main server module: listen on *:9422
no charts data file - initializing empty charts
mfschunkserver daemon initialized properly

在master启动监控/usr/local/mfs/sbin/mfscgiserv

挂载mfs（安装mfs客户端，如果在chunkserver或者master上挂载就不用按抓给客户端了）
useradd mfs -s /sbin/nologin
解压，安装和以上安装一样
配置脚本用./configure --prefix=/usr/local/mfs --with-default-user=mfs --with-default-group=mfs --enable-mfsmount && make && make install
echo “export PATH=$PATH:/usr/local/mfs/bin:/usr/local/mfs/sbin” >>/etc/portfile
export PATH=$PATH:/usr/local/mfs/bin:/usr/local/mfs/sbin
mkdir /mnt/mfs /mnt/mfsmeta  #创建挂载点
/usr/local/mfs/bin/mfsmount /mnt/mfs -H masterIP #挂载

df -h #查看挂载情况
