首先报错是这样的：
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
case 2:
^~~~
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[1]: *** [objs/Makefile:473: objs/src/core/ngx_murmurhash.o] Error 1
make[1]: Leaving directory '/root/nginx-1.10.1'
make: *** [Makefile:8: build] Error 2
原因，是将警告当成了错误处理，打开 nginx的安装目录/objs/Makefile，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
好的，第一个问题解决了，然后make又出现一个错误
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
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，条件限制，我们就进到源码里把这行直接注释掉
[root@iZgt88z6l1kvd7Z nginx-1.10.1]# vim src/os/unix/ngx_user.c
进去找到第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’?

^~~~~~~~~~~~~~~~~~~~~~~
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makefile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
[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
好嘞，查看版本 ，OK
我们再次进入nginx下
[root@iZgt88z6l1kvd7Z nginx-1.10.1]# ./configure --prefix=/usr/local/nginx --with-pcre=../pcre-8.39 --with-zlib=../zlib-1.2.8 --with-openssl=../opensll-1.1.0e
!注意这里还是要把objs/Makefile下的werror去掉
然后启动一下nginx
[root@iZgt88z6l1kvd7Z nginx-1.10.1]# /usr/local/nginx/sbin/nginx
设置一下环境变量
[root@iZgt88z6l1kvd7Z sbin]# echo "PATH=$PATH:/usr/local/nginx/sbin" >> /etc/profile && source /etc/profile
查看一下进程和端口是否开启
看看chrome能不能打开nginx的网页
