第一个，报错
- src/core/ngx_murmurhash.c: In function ‘ngx_murmur_hash2’:
- src/core/ngx_murmurhash.c:37:11: error: this statement may fall through [-Werror=implicit-fallthrough=]
- h ^= data[2] << 16;
- ^~~~~~~~~~~~~~
- src/core/ngx_murmurhash.c:38:5: note: here

- ^~~~
- src/core/ngx_murmurhash.c:39:11: error: this statement may fall through [-Werror=implicit-fallthrough=]
- h ^= data[1] << 8;
- ^~~~~~~~~~~~~
- src/core/ngx_murmurhash.c:40:5: note: here
- case 1:
- ^~~~
- cc1: all warnings being treated as errors

- make: *** [Makefile:8: build] Error 2
分析原因：
专注app软件定制开发是将警告当成了错误处理，打开 专注app软件定制开发的安装目录/objs/，去掉CFLAGS中的-Werror，再重新make
-Wall 表示打开gcc的所有警告
-Werror，它要求gcc将所有的警告当成错误进行处理
第二个，make出现的错误
- src/os/unix/ngx_user.c: In function ‘ngx_libc_crypt’:
- src/os/unix/ngx_user.c:36:7: error: ‘struct crypt_data’ has no member named ‘current_salt’
- cd.current_salt[0] = ~salt[0];
- ^
- make[1]: *** [objs/Makefile:774: objs/src/os/unix/ngx_user.o] Error 1
- make[1]: Leaving directory ‘/root/nginx-1.10.1‘
- make: *** [Makefile:8: build] Error 2
这里提示我们struct crypt_data’没有名为‘current_salt’的成员：cd.current_salt[0] = ~salt[0]；
最好的办法是换一个版本，因为条件限制，我们就进到源码里把这行直接注释掉好了。# vim src/os/unix/ngx_user.c进入里面注释掉36行
第三个错误openssl版本错误
- src/event/ngx_event_openssl.c: In function ‘ngx_ssl_dhparam’:
- src/event/ngx_event_openssl.c:954:11: error: dereferencing pointer to incomplete type ‘DH’ {aka ‘struct dh_st’}
- dh->p = BN_bin2bn(dh1024_p, sizeof(dh1024_p), NULL);
- ^~
- src/event/ngx_event_openssl.c: In function ‘ngx_ssl_connection_error’:
- src/event/ngx_event_openssl.c:1941:21: error: ‘SSL_R_NO_CIPHERS_PASSED’ undeclared (first use in this function); did you mean ‘SSL_R_NO_CIPHERS_SPECIFIED’?
- || n == SSL_R_NO_CIPHERS_PASSED /* 182 */
- ^~~~~~~~~~~~~~~~~~~~~~~
- SSL_R_NO_CIPHERS_SPECIFIED
- src/event/ngx_event_openssl.c:1941:21: note: each undeclared identifier is reported only once for each function it appears in
- make[1]: *** [objs/Makefile:816: objs/src/event/ngx_event_openssl.o] Error 1
- make[1]: Leaving directory ‘/root/nginx-1.10.1‘
- make: *** [Makefile:8: build] Error 2
原因：由于默认使用了openssl 1.1.x 版本，导致的API不一致引起
解决：
直接安装openssl1.0版本wget http://www.openssl.org/source/openssl-1.1.0e.tar.gz //下载openssl
[root@iZgt88z6l1kvd7Z ~]# tar -zxvf openssl-1.1.0e.tar.gz //解压
[root@iZgt88z6l1kvd7Z ~]# cd openssl-1.1.0e/ &&./config shared zlib --prefix=/usr/local/openssl && make && make install 进入目录把openssl编译安装到 /usr/local/openssl 下
[root@iZgt88z6l1kvd7Z openssl-1.1.0e]# ./config -t
[root@iZgt88z6l1kvd7Z openssl-1.1.0e]# make depend //一种度的规则，通过扫描仪个目录下的所有C\C++ 代码，从而判专断出文件之间的依赖关系，如a.cc文件中调用了b.h(如以形势include<b.h>)，如果之后a.cc文件被改动，那 么只需要重新编属译a.cc文件，不需要编译b.h文件。否则所有的文件都需要重新编译。
[root@localhost openssl-1.1.0e]# cd /usr/local
[root@iZgt88z6l1kvd7Z local]# ln -s openssl ssl
[root@iZgt88z6l1kvd7Z local]# echo "/usr/local/openssl/lib" >>/etc/ld.so.conf
[root@iZgt88z6l1kvd7Z local]# cd /root/openssl-1.1.0e注意每个人的目录都是不一样的，我这里是root下的openssl，至于其他人看自己情况，切换目录
[root@iZgt88z6l1kvd7Z openssl-1.1.0e]# ldconfig
[root@iZgt88z6l1kvd7Z openssl-1.1.0e]# echo $?
0
[root@iZgt88z6l1kvd7Z openssl-1.1.0e]# echo "PATH=$PATH:/usr/local/openssl/bin" >> /etc/profile && source /etc/profile
然后重新进入-1.9.9执行[root@iZwz967a5gqt3aqi2g3pbkZ nginx-1.9.9]# ./configure --prefix=/usr/local/nginx --add-module=/root/nginx-1.9.9/headers-more-nginx-module-0.33 --with-http_stub_status_module --with-http_ssl_module注意，我这里的是这条命令，至于你们的./configure……就看你们自身情况
重新make一下哎
