nginx安装http2.0协议

1.HTTP2协议 

  • HTTP 2.0 的主要目标是改进传输性能，实现低延迟和高吞吐量。从另一方面看，HTTP 的高层协议语义并不会因为这次版本升级而受影响。所有HTTP 首部、值，以及它们的使用场景都不会变。
  • 现有的任何网站和应用，无需做任何修改都可以在HTTP 2.0 上跑起来。不用为了利用HTTP 2.0 的好处而修改标记。HTTP 服务器必须运行HTTP 2.0 协议，但大部分用户都不会因此而受到影响

2.编译安装nginx

#1.安装依赖
[root@hadoop_node1 ~]# yum install  -y  gcc  gcc-c++  pcre  pcre-devel  openssl-devel  zlib  zlib-devel
#2.下载安装
[root@hadoop_node1 ~]# cd /usr/local/src/
[root@hadoop_node1 src]# wget http://nginx.org/download/nginx-1.10.3.tar.gz
[root@hadoop_node1 src]# tar xf nginx-1.10.3.tar.gz 
[root@hadoop_node1 src]# cd nginx-1.10.3/
#3.编译参数
[root@hadoop_node1 nginx-1.10.3]# ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx-1.10.3 --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module
[root@hadoop_node1 nginx-1.10.3]# make && make install

 

  • --with-http_v2_module 支持http2协议

  • [root@rbtnode1 ~]# /usr/local/nginx/sbin/nginx -V   查看当前手动安装的模块
    nginx version: nginx/1.14.2
    built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)
    built with OpenSSL 1.0.2k-fips 26 Jan 2017
    TLS SNI support enabled
    configure arguments: --with-http_ssl_module --with-stream --with-http_stub_status_module --with-http_v2_module
    You have new mail in /var/spool/mail/root
    [root@rbtnode1 ~]#

3.生成证书

  • 因为没有真的证书，所以生成一个伪证书
[root@hadoop_node1 nginx-1.10.3]# ln -s /usr/local/nginx-1.10.3/ /usr/local/nginx
[root@hadoop_node1 nginx-1.10.3]# cd /usr/local/nginx/conf/
[root@hadoop_node1 conf]# mkdir key
[root@hadoop_node1 conf]# cd key/
#自定义密码
[root@hadoop_node1 key]# openssl genrsa -des3 -out server.key 1024
Generating RSA private key, 1024 bit long modulus
..........++++++
..........++++++
e is 65537 (0x10001)
Enter pass phrase for server.key:
Verifying - Enter pass phrase for server.key:
#签发证书
[root@hadoop_node1 key]# openssl req -new -key server.key -out server.csr
Enter pass phrase for server.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:BJ
Locality Name (eg, city) [Default City]:BJ
Organization Name (eg, company) [Default Company Ltd]:SDU
Organizational Unit Name (eg, section) []:SA
Common Name (eg, your name or your server's hostname) []:xiaojin
Email Address []:123@qq.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:123456
An optional company name []:123456
[root@hadoop_node1 key]# cp server.key server.key.ori
[root@hadoop_node1 key]# openssl rsa -in server.key.ori -out server.key
Enter pass phrase for server.key.ori:
writing RSA key
[root@hadoop_node1 key]# openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
Signature ok

            index  index.html index.htm;
        }
        location = /50x.html {
            root   html;
        }
    }
}
  • 检查防火墙是否开启，是否开启8443和80端口

  • 验证方法
  • 方法一
  1. 使用Chrome访问启用http2的站点，比如Jackie的环境为https://10.0.0.71:8443。
  2. 新开TAB页，在地址栏中输入chrome://net-internals/#http2，检查HTTP/2 sessions下的表格。
  3. 确认表格里是否出现了上一步访问的主机地址，比如10.0.0.71:8443。
  • 方法二
  1. 使用curl命令，参考HTTP/2 with curl，执行如下命令，确认站点返回的协议是否为HTTP
  2. curl --http2 -I 10.0.0.71:8443
  3. 如执行上述命令时遇到如下错误，说明系统当前安装的curl还不支持HTTP2协议。
  4. curl https://10.0.0.71:8443/ --http2 curl: (1) Unsupported protocol
  5. 可以执行如下命令，检查系统当前安装的curl支持的特性列表，确认是否包含HTTP2。
  6. curl -V curl 7.47.0 (i686-pc-linux-gnu) libcurl/7.47.0 GnuTLS/3.4.10 zlib/1.2.8 libidn/1.32 librtmp/2.3 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtmp rtsp smb smbs smtp smtps telnet tftp Features: AsynchDNS IDN IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz TLS-SRP UnixSockets
  7. 从前述输出信息可以了解到，当前安装的curl还不支持HTTP2。
  8. 这时可参考如何启用curl命令HTTP2支持重新编译curl，加入HTTP2的支持。
  • 方法三
  1. 安装Chrome插件HTTP/2 and SPDY indicator，安装完毕后访问启用HTTP2的站点，如果地址栏出现蓝色的闪电，说明站点已启用HTTP2。
