CentOS下搭建文件共享服务
nfs部署以及优化
Server端配置
安装rpm服务包
yum install -y nfs-utils
创建数据挂载点
mkdir -p /data
编辑exports文件
vi /etc/exports
[root@localhost /]# cat /etc/exports
/data/ 192.168.211.0/24(rw,sync,no_root_squash)
启/停服务
/etc/init.d/rpcbind stop
/etc/init.d/nfs stop
/etc/init.d/rpcbind start
/etc/init.d/nfs start
确认
exportfs –v
[root@localhost /]# exportfs -v
/data 192.168.211.0/24(rw,wdelay,no_root_squash,no_subtree_check,sec=sys,rw,no_root_squash,no_all_squash)
[root@localhost /]#
Client配置
查看showmount命令得安装服务包
yum install -y nfs-utils
查看nfs server共享目录
showmount -e 192.168.211.128
[root@localhost /]# showmount -e 192.168.211.128
Export list for 192.168.211.128:
/data 192.168.211.0/24
[root@localhost /]#
创建client挂载点
mkdir -p /nfs-data/
挂载nfs共享目录
mount -t nfs 192.168.211.128:/data/ /nfs-data/
确认
[root@localhost nfs-data]# df -h

[root@localhost nfs-data]#
exports配置参数详细说明
rw:读写
ro：只读
sync同步模式，由内存数据写入硬盘
async不同步，内存数据定期写入磁盘
no_root_squash,root用户对共享目录拥有最高权限。
root_squash：root用户对共享目录权限不高，只有普通用户权限，限制了root
all_squash：不管使用nfs用户是谁，都会被限定为一个指定的普通用户身份。
anonuid、anongid：要和root_squash和all_squash一起使用，用于指定nfs用户限定后的uid和gid，前提是本机/etc/passwd中存在这个uid和gid。
showmount参数说明
showmount –e 加ip查看nfs共享情况
exportfs参数说明
-a全部挂载或者卸载
-r重新挂载
-u卸载某一个目录
-v显示共享的目录
samba部署和优化
Server端配置
安装软件
yum install -y samba samba-client
备份主配置文件
cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
编辑主配置文件
vim /etc/samba/smb.conf
# --------------------------- Logging Options -----------------------------
#
# Log File let you specify where to put logs and how to split them up.
#
# Max Log Size let you specify the max size log files should reach
///保持默认
# logs split per machine
log file = /var/log/samba/log.%m
# max 50KB per log file, then rotate
max log size = 50
# ----------------------- Standalone Server Options ------------------------
#
# Scurity can be set to user, share(deprecated) or server(deprecated)
#
# Backend to store user information in. New installations should
# use either tdbsam or ldapsam. smbpasswd is available for backwards
# compatibility. tdbsam requires no further configuration.
///保持默认
security = user
passdb backend = tdbsam
# --------------------------- Printing Options -----------------------------
#
# Load Printers let you load automatically the list of printers rather
# than setting them up individually
#
# Cups Options let you pass the cups libs custom options, setting it to raw
# for example will let you use drivers on your Windows clients
#
# Printcap Name let you specify an alternative printcap file
#
# You can choose a non default printing system using the Printing option
///保持默认
load printers = yes
cups options = raw
///***自定义***
map to guest = bad user
guest account = nobody
encrypt password = yes
smb passwd file = /etc/samba/smbpasswd
#============================ Share Definitions ==============================
///***自定义配置share ***
[share]
comment = share all
path = /tmp/samba
browseable = yes
guest ok = yes
writable = yes
printable = no
create mask = 0644
directory mask = 0755
///***自定义配置Non-share ***
[myshare]
comment = share for users
path = /samba
browseable = yes
writable = yes
public = no
guest ok = no
force user = root
printable = no
create mask = 0644
directory mask = 0755
创建share目录
mkdir /tmp/samba
chmod 777 /tmp/samba/
touch /tmp/samba/sharefiles
echo "Hello,world" >/tmp/samba/sharefiles
创建non-share目录
mkdir /samba
chmod 777 /samba
测试
testparm
建立用户
useradd user1
useradd user2
pdbedit -a user1
pdbedit -a user2
查看
pdbedit -L
Client配置
安装client软件
yum install samba-client
linux client 浏览共享
smbclient //192.168.211.128/myshare -U user1
挂载
mount -t cifs //192.168.211.128/myshare /mnt -o username=user1,password=root1234
window访问：
file://192.168.211.128
