编译nginx时openssl报错的解决方案

编译nginx时提示openssl版本错误

分析原因：

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

解决办法：

直接编译安装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  //是一种makefile的规则，通过扫描仪个目录下的所有CC++ 代码，从而判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      #添加环境变量

好嘞，查看openssl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  
make && make install      #编译安装
/usr/local/nginx/sbin/nginx       #启动nginx

查看一下进程和端口是否开启

查看浏览器能不能正常打开nginx的网页
