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

[root@localhost conf]# /usr/local/nginx/sbin/nginx
/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
从错误看出是缺少lib文件导致，进一步查看下

[root@localhost conf]# ldd $(which /usr/local/nginx/sbin/nginx)
linux-gate.so.1 =>  (0x0071b000)
libpthread.so.0 => /lib/libpthread.so.0 (0×00498000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0×00986000)
libpcre.so.1 => not found
libcrypto.so.6 => /lib/libcrypto.so.6 (0×00196000)
libz.so.1 => /lib/libz.so.1 (0×00610000)
libc.so.6 => /lib/libc.so.6 (0x002d7000)
/lib/ld-linux.so.2 (0x006a8000)
libdl.so.2 => /lib/libdl.so.2 (0x008c3000)
可以看出 libpcre.so.1 => not found 并没有找到，进入/lib目录中手动链接下
[root@localhost lib]# ln -s libpcre.so.0.0.1 libpcre.so.1
然后在启动nginx  ok 了
[root@localhost lib]# /usr/local/nginx/sbin/nginx
[root@localhost lib]# ps -ef |grep nginx
