ngnix在檢查是否可啟動的時候，出現下面問題：

(venv) [email protected]:/data/server/nginx#./sbin/nginx -t
    ./sbin/nginx:error while loading shared libraries: libpcre.so.1: cannot open shared objectfile: No such file or directory

分析：

1、先看報錯
2、思考，是否報錯真實有效
	分析： 誰錯了
3、查詢檔案
	全名找不到，我們使用正則
4、找到檔案，我沒有問題
	nginx預設找庫檔案的路徑有問題
5、解決
 

解決：

(venv) [email protected]:/data/soft/nginx-1.10.2#ldd /data/server/nginx/sbin/nginx 
        linux-vdso.so.1 =>  (0x00007ffdb9154000)
        libdl.so.2 =>/lib/x86_64-linux-gnu/libdl.so.2 (0x00007fa59379b000)
        libpthread.so.0 =>/lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fa59357e000)
        libcrypt.so.1 =>/lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007fa593345000)
        libpcre.so.1 => not found
        libc.so.6 =>/lib/x86_64-linux-gnu/libc.so.6 (0x00007fa592f7c000)
        /lib64/ld-linux-x86-64.so.2(0x0000564bfef41000)
 

查詢檔案：

(venv) [email protected]:/data/soft/nginx-1.10.2#find / -name "libpcre.so.1"
/data/soft/pcre-8.39/.libs/libpcre.so.1
/usr/local/lib/libpcre.so.1
...

連結該檔案

(venv) [email protected]:/data/soft/nginx-1.10.2#ln -s /usr/local/lib/libpcre.so.1 /lib/x86_64-linux-gnu/

再次檢查一下nginx的配置檔案

(venv) [email protected]
 
:/data/soft/nginx-1.10.2#/data/server/nginx/sbin/nginx -t

nginx:the configuration file /data/server/nginx/conf/nginx.conf syntax is ok

nginx:configuration file /data/server/nginx/conf/nginx.conf test is successful
