Nginx啟動出錯 error while loading shared libraries:

在centos5.7 32位上編譯安照 nginx-1.1.16 出錯

[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

從錯誤看出是缺少lib文件導致，進一步查看下

[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 並沒有找到，進入/lib目錄中手動鏈接下

[root@localhost lib]# ln -s libpcre.so.0.0.1 libpcre.so.1

然后在啟動nginx ok 了
 
[root@localhost lib]# /usr/local/nginx/sbin/nginx
[root@localhost lib]# ps -ef |grep nginx
root 9539 1 0 19:06 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
