使用的是原始碼的安裝,就是用的.tar.gz檔案,
1.安裝完之後,啟動不了.報錯,錯誤如下:

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

進一步檢視問題出在哪,執行如下命令

ldd $(which /usr/local/nginx/sbin/nginx)

顯示如下:

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  //問題在這
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目錄中手動連結下
手動新增一個連結到lib目錄下

ln -s /usr/local/lib/libpcre.so.0.0.1  /lib/libpcre.so.1  //具體的路徑根據自己libpcre.so.0.0.1的位置決定

就可以了
2. 檢視配置檔案是不是正確

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

3.根據配置檔案啟動

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

4.停止

/usr/local/nginx/sbin/nginx -s stop
 

5.重啟

/usr/local/nginx/sbin/nginx -s reload
