两台文件fastDFS文件服务器 服务器A: 192.168.10.157 服务器B:192.168.10.158 上面 实现目的： 增加一台fastDFS备份服务器（192.168.10.158）， 做为fastDFS文件服务器（192.168.10.157） 的从服务器，这两台fastDFS文件服务器之间实现双机热备。 从服务器（192.168.10.158） 上面数据 永远与主服务器（192.168.10.157） 上面数据保 持同步，并且随着主服务器（192.168.10.157） 上面数据的 变化而变化。环境说明 系统：CentOS 6.6 IP：192.168.10.157 FastDFS_v5.03.+nginx-1.6.2+libevent-2.0.21-stable 系统：CentOS 6.6 IP：192.168.10.158 FastDFS_v5.03.+nginx-1.6.2+libevent-2.0.21-stable 备注：作为主从服务器的fastDFS和nginx 版本建议使用同一版本！ 开始： 一、安装libevent 说 明：在两台MySQL服务器192.168.10.157和192.168.21.158上分别进行如下操作， 1、下载libevent-2.0.21-stable.tar.gz http://sourceforge.net/ 2、解压并安装配置 tar -zxvf libevent-2.0.21-stable.tar.gz cd libevent-2.0.21-stable mkdir -p /usr/local/libevnet ./configure --prefix=/usr/local/libevent make && make install #为libevent创建软链接到/lib库下，64位系统对应/lib64 ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5 ln -s /usr/local/libevent/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5 到此，libevent安装完成！二、安装fastDFS文件服务器 1、 下载lFastDFS_v5.03.tar.gz http://sourceforge.net/projects/fastdfs/ 2、解压并安装配置 tar zxvf FastDFS_v5.03.tar.gz cd FastDFS vim make.sh #WITH_LINUX_SERVICE=1 /取消此行的注释 ./make.sh ./make.sh install 涉及ip的文件: /etc/fdfs/storage.conf /etc/fdfs/client.conf /etc/fdfs/mod_fastdfs.conf 涉及目录的文件: /etc/fdfs/storage.conf /etc/fdfs/tracker.conf /etc/fdfs/client.conf /etc/fdfs/mod_fastdfs.conf #trackerd /usr/local/bin/stop.sh /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf /usr/local/bin/restart.sh /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf #storaged /usr/local/bin/stop.sh /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf /usr/local/bin/restart.sh /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf 3、建立存储路径并配置fastDFS_v5.03 mkdir -p /www/geebook_storage #建立storage存储目录 mkdir -p /www/geebook_tracker #建立tracker调度器目录 #建立client客户端目录 cp /etc/fdfs/storage.conf /etc/fdfs/storage.conf-bak #备份配置文件 cp /etc/fdfs/tracker.conf /etc/fdfs/tracker.conf-bak #备份配置文件 cp /etc/fdfs/client.conf /etc/fdfs/client.conf-bak #备份配置文件 vi /etc/fdfs/storage.conf #修改storage配置文件修改参数 base_path=/www/geebook_stoarge # the base path to store data and log files store_path0=/www/geebook_storage # store_path#, based 0, if store_path0 not exists, it's value is base_path tracker_server=192.168.10.157 # 指定tracker server地址 可以有多个同步的IP tracker_server=192.168.10.158 vi /etc/fdfs/tracker.conf #修改tracker配置文件修改参数 base_path=/www/geebook_tracker #
