二，Master server安装及配置：
1，建组及用户：
groupadd mfs
useradd -g mfs mfs
2，编译及安装：
./configure --prefix=/usr/local/mfs --sysconfdir=/etc --localstatedir=/var/lib --with-default-user=mfs --with-default-group=mfs --disable-mfschunkserver --disable-mfsmount
make && make install
3，更改相关文件：
[root@localhost mfs]# cd /etc/
[root@localhost etc]# cp mfsmaster.cfg.dist mfsm
mfsmaster.cfg.dist mfsmetalogger.cfg.dist
[root@localhost etc]# cp mfsmaster.cfg.dist mfsmaster.cfg
[root@localhost etc]# cp mfsmetalogger.cfg.dist mfsmetalogger.cfg
[root@localhost etc]# cp mfsexports.cfg.dist mfsexports.cfg
[root@localhost mfs]# cd /var/lib/mfs/
[root@localhost mfs]# cp metadata.mfs.empty metadata.mfs
[root@localhost etc]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.0.180 mfsmaster
4，启动服务：
[root@localhost mfs]# /usr/local/mfs/sbin/mfsmaster start
working directory: /var/lib/mfs
lockfile created and locked
initializing mfsmaster modules ...
loading sessions ... ok
sessions file has been loaded
exports file has been loaded
loading metadata ...
create new empty filesystemmetadata file has been loaded
no charts data file - initializing empty charts
master <-> metaloggers module: listen on *:9419
master <-> chunkservers module: listen on *:9420
main master server module: listen on *:9421
mfsmaster daemon initialized properly
root@localhost mfs]# /usr/local/mfs/sbin/mfscgiserv
starting simple cgi server (host: any , port: 9425 , rootpath: /usr/local/mfs/share/mfscgi)
三，Matelogger Server安装及配置：
1，建组及用户：
groupadd mfs
useradd -g mfs mfs
mkdir -p /var/bak/mfschunk01/
chown mfs.mfs /var/bak/mfschunk01/
2，编译及安装：
./configure --prefix=/usr/local/mfs --sysconfdir=/etc --localstatedir=/var/lib --with-default-user=mfs --with-default-group=mfs --disable-mfschunkserver --disable-mfsmount
make && make install
3，更改相关文件：
[root@localhost mfs-1.6.17]# cd /etc/
[root@localhost etc]# cp mfsmetalogger.cfg.dist mfsmetalogger.cfg
[root@localhost etc]# vi /etc/mfsmetalogger.cfg
MASTER_HOST = mfsmaster
MASTER_PORT = 9419
#去掉上面2行的注释
[root@localhost etc]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 sworddb.com localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
114.80.160.5 kuafu.com
192.168.0.178 mfsmaster
4，启动服务：
[root@localhost etc]# /usr/local/mfs/sbin/mfsmetalogger start
working directory: /var/lib/mfs
lockfile created and locked
initializing mfsmetalogger modules ...
mfsmetalogger daemon initialized properly
四，Chunk Server 1 安装及配置：
1，建组及用户：
groupadd mfs
useradd -g mfs mfs
2，编译及安装：
./configure --prefix=/usr/local/mfs --sysconfdir=/etc --localstatedir=/var/lib --with-default-user=mfs --with-default-group=mfs --disable-mfsmaster
make && make install
3，更改相关文件：
[root@localhost mfs-1.6.17]# cd /etc/
[root@localhost etc]# cp mfschunkserver.cfg.dist mfschunkserver.cfg
[root@localhost etc]# cp mfshdd.cfg.dist mfshdd.cfg
[root@localhost etc]#
[root@localhost var]# mkdir -p /var/bak/mfschunk01
[root@localhost var]# chown -R mfs:mfs /var/bak/mfschunk01/
[root@localhost var]# vi /etc/mfshdd.cfg
# mount points of HDD drives
#
#/mnt/hd1
#/mnt/hd2
#etc.
/var/bak/mfschunk01/
[root@sworddb mfschunk02]# vi /etc/mfschunkserver.cfg
WORKING_USER = mfs
WORKING_GROUP = mfs
MASTER_HOST = mfsmaster
MASTER_PORT = 9420
MASTER_TIMEOUT = 60
#去掉上面5行前的注释
~
[root@localhost var]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
#192.168.0.180 magicdb.com
192.168.0.180 mfsmaster
4，启动服务：
[root@localhost var]# /usr/local/mfs/sbin/mfschunkserver start
working directory: /var/lib/mfs
lockfile created and locked
initializing mfschunkserver modules ...
hdd space manager: scanning folder /var/bak/mfschunk01/ ...
hdd space manager: /var/bak/mfschunk01/: 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
注：重复上面步骤安装Chunk Server 2,有以下2个需要注意的地方：
mkdir -p /var/bak/mfschunk02/
[root@localhost var]# vi /etc/mfshdd.cfg
# mount points of HDD drives
#
#/mnt/hd1
#/mnt/hd2
#etc.
/var/bak/mfschunk02/
五，Client 安装及配置：
1，安装FUSE:
[root@youxia197 local]# tar -zxvf fuse-2.7.4.tar.gz
[root@youxia197 local]# cd fuse-2.7.4
[root@youxia197 fuse-2.7.4]# ./configure
[root@youxia197 fuse-2.7.4]# make && make install
2，编译及安装：
[root@youxia197 local]# cd mfs-1.6.17
./configure --prefix=/usr/local/mfs --sysconfdir=/etc --localstatedir=/var/lib --with-default-user=mfs --with-default-group=mfs --enable-mfsmount --disable-mfsmaster --disable-mfschunkserver
[root@youxia197 mfs-1.6.17]# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH
3，连接mfsmaster服务器：
[root@youxia197 opt]# /usr/local/mfs/bin/mfsmount /mnt/mfs/ -H mfsmaster
mfsmaster accepted connection with parameters: read-write,restricted_ip ; root mapped to root:root
[root@youxia197 ~]# df -h | grep mfs
mfs#mfsmaster:9421 157G 529M 156G 1% /mnt/mfs
4，设置文件副本数量为3：
[root@youxia197 opt]# /usr/local/mfs/bin/mfsrsetgoal 3 /mnt/mfs
deprecated tool - use "mfssetgoal -r"
/mnt/mfs:
inodes with goal changed: 5
inodes with goal not changed: 0
inodes with permission denied: 0
[root@youxia197 opt]#
5，复制一个文件到/mnt/mfs目录中，并查看副本数量：
[root@youxia197 mfs]# /usr/local/mfs/bin/mfsgetgoal /mnt/mfs/mfs-1.6.17.tar.gz
/mnt/mfs/mfs-1.6.17.tar.gz: 3
