centos6.5下搭建fastdfs分布式存储
FastDFS分布式文件系统环境介绍系统：centos6.5_64_mini
FastDFS版本：FastDFS_v5.01
实验节点如下：（注：以下两个节点的安装及配置完全相同）
SERVER1 IP:192.168.100.250
SERVER2 IP:192.168.100.251
1：安装定时同步相关
#yum install -y ntpdate
#cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
#ntpdate us.pool.ntp.org
2：配置时间同步
#crontab -e
3：输入以下代码
*/10 * * * * /usr/sbin/ntpdate us.pool.ntp.org | logger -t NTP
4：安装相关依赖包
#yum -y install gcc gcc-c++ openssl openssl-devel pcre-devel perl wget
#mkdir /yunwei8/soft
#cd /yunwei8/soft
5：下载所需的安装包至soft文件夹下
# wget http://down.yunwei8.com/soft/linux/libevent-2.0.21-stable.tar.gz
# wget http://down.yunwei8.com/soft/linux/FastDFS_v5.01.tar.gz
#wget http://down.yunwei8.com/soft/linux/fastdfs-nginx-module_v1.15.tar.gz
#wget http://down.yunwei8.com/soft/linux/nginx-1.6.0.tar.gz
6：删除自带libevent
#rpm -qa libevent
#rpm -e --nodeps libevent-1.4.13-4.el6.x86_64
7：安装libevent-2.0.21
#cd /yunwei8/soft/
#tar -zxvf libevent-2.0.21-stable.tar.gz
#cd libevent-2.0.21-stable
#./configure
#make && make install
8：为libevent创建软链接到/lib库下，64位系统对应/lib64
#ln -s /usr/local/lib/libevent* /lib64/
#ln -s /usr/local/lib/libevent* /lib/
9：安装FastDFS_v5.01
#cd /yunwei8/soft
#tar -zxvf FastDFS_v5.01.tar.gz
#cd FastDFS/
#./make.sh
#./make.sh install
10：配置跟踪器tracker server
10.1建立文件夹
#mkdir -p /yunwei8/data/fastdfs
10.2修改tracker参数,找到base_path=/home/yuqing/fastdfs修改如下
#vi /etc/fdfs/tracker.conf
base_path=/yunwei8/data/fastdfs
11：启动tracker服务
#/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
#echo '/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf' >> /etc/rc.local
12：配置存储服务storage server，并修改相关参数
#mkdir -p /yunwei8/data/fastdfs 注：（若tracker和storage在不同服务器则需建立）
#mkdir /yunwei8/data/images
#vi /etc/fdfs/storage.conf
找到base_path=/home/yuqing/fastdfs，修改如下
base_path=/yunwei8/data/fastdfs
找到store_path0=/home/yuqing/fastdfs，修改如下
store_path0=/yunwei8/data/images
找到tracker_server=192.168.209.121:22122，修改如下
tracker_server=192.168.100.251:22122
tracker_server=192.168.100.250:22122
13：启动storage服务
#/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
会显示一长串如下的内容
mkdir data path: 00 ...
mkdir data path: 01 ...
mkdir data path: 02 ...
mkdir data path: 03 ...
mkdir data path: 04 ...
mkdir data path: 05 ...
mkdir data path: 06 ...
写入开机自启动
#echo '/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf' >> /etc/rc.local
14：在storage server安装nginx模块
#cd /yunwei8/soft/
#tar -zxvf fastdfs-nginx-module_v1.15.tar.gz
#tar -zxvf nginx-1.6.0.tar.gz
#cd nginx-1.6.0
#./configure --prefix=/yunwei8/server/nginx --add-module=../fastdfs-nginx-module/src
#make && make install
15：修改nginx参数配置如下
#vi /yunwei8/server/nginx/conf/nginx.conf
worker_processes1;
events {
worker_connections1024;
}
http {
include mime.types;
default_typeapplication/octet-stream;
sendfile on;
keepalive_timeout65;
server {
listen 80;
server_namelocalhost;
location /group1/M00 {
alias /data/images/data;
ngx_fastdfs_module;
}
}
}
16：编写nginx 启动脚本
#vi /etc/init.d/nginx
输入以下代码并保存
#!/bin/sh## nginx - this script starts and stops the nginx daemin## chkconfig: - 85 15 # description:Nginx is an HTTP(S) server, HTTP(S) reverse \# proxy and IMAP/POP3 proxy server# processname: nginx# config: /yunwei8/server/nginx/conf/nginx.conf# pidfile: /yunwei8/server/nginx/logs/nginx.pid# Source function library.. /etc/rc.d/init.d/functions# Source networking configuration.. /etc/sysconfig/network# Check that networking is up.[ "$NETWORKING" = "no" ] && exit 0nginx="/yunwei8/server/nginx/sbin/nginx"prog=$(basename $nginx)NGINX_CONF_FILE="/yunwei8/server/nginx/conf/nginx.conf"lockfile=/var/lock/subsys/nginxstart() { [ -x $nginx ] || exit 5 [ -f $NGINX_CONF_FILE ] || exit 6 echo -n $"Starting $prog: " daemon $nginx -c $NGINX_CONF_FILE retval=$? echo [ $retval -eq 0 ] && touch $lockfile return $retval}stop() { echo -n $"Stopping $prog: " killproc $prog -QUIT retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile return $retval}restart() { configtest || return $? stop start}reload() { configtest || return $? echo -n $"Reloading $prog: " killproc $nginx -HUP RETVAL=$? echo}configtest() {$nginx -t -c $NGINX_CONF_FILE}rh_status() { status $prog}rh_status_q() { rh_status >/dev/null 2>&1}case "$1" in start) rh_status_q && exit 0 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart|configtest) $1 ;; reload) rh_status_q || exit 7 $1 ;; status) rh_status ;; *) echo $"Usage: $0 {start|stop|status|restart|reload|configtest}" exit 2esac 17：保存后，设置权限并添加到启动服务列表中
#chmod 755 /etc/init.d/nginx
#chkconfig --add nginx
#chkconfig --level 345 nginx on
18：启动nginx服务
#service nginx start
19：给storage的存储目录做一个软连接
#ln -s /yunwei8/data/images/data/ /yunwei8/data/images/data/M00
20：拷贝mod_fastdfs.conf到/etc/fdfs/
#cp /yunwei8/soft/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
21：修改mod_fastdfs.conf配置
#vi /etc/fdfs/mod_fastdfs.conf
找到base_path=/tmp，修改为如下
base_path=/yunwei8/data/fastdfs
找到store_path0=/home/yuqing/fastdfs，修改如下
store_path0=/yunwei8/data/images
找到url_have_group_name = fasle，修改如下
url_have_group_name = true
找到tracker_server=tracker:22122，修改如下
tracker_server=192.168.100.251:22122
tracker_server=192.168.100.250:22122
22：在tracker server上配置client
#vi /etc/fdfs/client.conf
修改client参数，找到base_path=/home/yuqing/fastdfs，修改如下
base_path=/yunwei8/data/fastdfs
找到tracker_server=192.168.0.197:22122，修改如下
tracker_server=192.168.100.250:22122
tracker_server=192.168.100.251:22122
23：防火墙开放相应端口
#/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
#/sbin/iptables -I INPUT -p tcp --dport 22122-j ACCEPT
#/etc/rc.d/init.d/iptables save
24：创建测试文件
#cd /yunwei8/
创建网页名为yunwei8.html
#vi yuwnei8.html
输入网页内容
yunwei8
25：退出和重启
25.1退出
直接kill即可让server进程正常退出，可以使用killall命令，例如：
#killall fdfs_trackerd
#killall fdfs_storaged
也可以使用FastDFS自带的stop.sh脚本，如：
#/usr/local/bin/stop.sh/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
#/usr/local/bin/stop.sh/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
stop.sh只会停止命令行（包括参数）完全相同的进程。
千万不要使用-9参数强杀，否则可能会导致binlog数据丢失的问题。
25.2重启
可以kill掉server进程后，执行启动命令行。如：
#killall fdfs_trackerd
#killall fdfs_storaged
#/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
#/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
或者直接使用FastDFS自带的restart.sh脚本，如：
#/usr/local/bin/restart.sh/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
#/usr/local/bin/restart.sh/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
26：上传测试 /usr/local/bin/restart.sh/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
#/usr/local/bin/fdfs_test /etc/fdfs/client.conf upload/yunwei8/yunwei8.html (绝对路径）
27：访问上传输出的测试地址
