出现提示错误openssl版本错误

分析原因：由于yum默认使用了openssl 1.1.x 版本，导致的API不一致引起的

解决：

直接安装openssl1.0版本
wget http://www.openssl.org/source/openssl-1.1.0e.tar.gz
tar -zxvf openssl-1.1.0e.tar.gz
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
./config -t
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。

cd /usr/local
ln -s openssl ssl
echo "/usr/local/openssl/lib" >>/etc/ld.so.conf
ldconfig
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

./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

/usr/local/nginx/sbin/nginx

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

OK
