猜测可能有以下 3 种原因:
未安装 PCRE
libpcre.so.1 名字不对
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
