FastDfs的安装

一) 安装libevent
下载: wget -c http://monkey.org/~provos/libevent-1.4.14b-stable.tar.gz
解压：tar -xzvf libevent-1.4.14b-stable.tar.gz
安装：cd libevent-1.4.14b-stable
./configure --prefix=/usr
make
make install
删除中间文件：rm libevent-1.4.14b-stable.tar.gz
rm -rf libevent-1.4.14b-stable

二）安装FastDFS
下载源码包：wget http://fastdfs.googlecode.com/files/FastDFS_v4.06.tar.gz
解压：tar -xzvf FastDFS_v4.06.tar.gz
创建目录：mkdir -p /home/moon/dfs
拷贝程序到dfs下：cp -r FastDFS /home/moon/dfs/FastDFS
如果需要支持HTTP，修改FastDFS下的make.sh, 将 #WITH_HTTPD=1前的注释符去掉
编译：./make.sh
使用root权限或sudo安装：./make.sh install

新建文件：
/home/moon/dfs/FastDFS/conf/tracker_1.conf
/home/moon/dfs/FastDFS/conf/storage_1.conf

修改tracker和storage服务器配置文件

启动tracker server和storage
sudo /home/moon/dfs/FastDFS/tracker/fdfs_trackerd /home/moon/dfs/FastDFS/conf/tracker_1.conf
sudo /home/moon/dfs/FastDFS/storage/fdfs_storaged /home/moon/dfs/FastDFS/conf/storage_1.conf

启动时报错，/home/moon/dfs/FastDFS/storage/fdfs_storaged: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory
解决方法
1. 首先 find / -name libevent-1.4.so.2 找到缺少的链接文件到底在那儿。
2. LD_DEBUG=libs /usr/local/bin/fdfs_storaged
3. 从Debug信息中就知道程序去哪里找链接库了。我这边程序去 trying file=/lib64/libevent-1.4.so.2 而我的链接库的实际存储位置是/usr/lib/libevent-1.4.so.2
4. 做一个软连接 ln -s /usr/lib/libevent-1.4.so.2 /lib64/libevent-1.4.so.2
