Nginx 启动出错 error while loading shared libraries: libpcre.so.1

error while loading shared libraries: libpcre.so.1

启动 nginx 时报错:

/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

猜测可能有以下 3 种原因:

  1. 未安装 PCRE
  2. libpcre.so.1 名字不对
  3. 未设置 LD_LIBRARY_PATH

安装 PCRE,不用多说。安装完之后仍出现以上报错呢。?

find / -name libpcre.so.1 

发现找不到 libpcre.so.1 怎么办

到 /usr/local/lib 目录下查看

ls -l libpcre.so*
lrwxrwxrwx 1 root root     17 7月   4 09:06 libpcre.so -> libpcre.so.1.2.10
-rwxr-xr-x 1 root root 508296 7月   4 09:06 libpcre.so.1.2.10

发现原来是名字不对,遂设置软连接

ln -s /usr/local/lib/libpcre.so.1.2.10 libpcre.so.1

设置完软连接重启 nginx 发现仍然无法解决问题。

设置 LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

最终,问题解决。
