>/usr/local/nginx/sbin/nginx -t报错，错误如下：

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

>cd /lib64/

>ll  | grep pcre

发现少了一个符号链接，手动添加

>ln -s libpcre.so.0.0.1 libpcre.so.1

>/usr/local/nginx/sbin/nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

搞定！
