安装程序后加载共享库时出错

我正在安装rfc5766-转服务器。但它无法启动并出现错误：

error while loading shared libraries: libevent_core-2.0.so.5: cannot open shared object file: No such file or directory

这是我如何进行安装的复制粘贴：

$ cd /var/tmp;
wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz; tar xvfz libevent-2.0.21-stable.tar.gz; cd libevent-2.0.21-stable; ./configure; make; make install;
wget http://rfc5766-turn-server.googlecode.com/files/turnserver-1.8.6.3.tar.gz ; tar xvfz turnserver-1.8.6.3.tar.gz; cd turnserver-1.8.6.3; ./configure; make; make install;
/var/tmp/turnserver-1.8.6.3/bin/turnserver;

我尝试了这个，但没有帮助（同样的错误）：

$ ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5;
/var/tmp/turnserver-1.8.6.3/bin/turnserver ;

编辑：（如果我按如下方式运行，则无需更改即可运行它，但是当我使用客户端进行测试时，它不会显示 TURN 正在命中或客户端到达的任何类型的日志）

首先，一个明显的问题：该库是否已安装？

还有安装了吗为了正确的架构？ （例如，32 位可执行文件需要 32 位库，64 位可执行文件需要 64 位库。）

如果您刚刚将库添加到系统库路径中的目录中，则需要运行ldconfig作为根。有已安装库的缓存，并ldconfig重建该缓存。如果某个库存在于目录中但不在缓存中，则不会使用它。

我看到您将库添加到了/usr/local/lib.大多数发行版将其包含在默认库路径中，但 Red Hat 没有。将其添加到/etc/ld.so.conf然后运行ldconfig。

运行ldd /path/to/excecutable以查看可执行文件在哪里找到其库。当找不到库时，strace /path/to/executable会告诉您程序在哪里寻找它。
