CentOS 7 编译安装nginx并启用TLS1.3

暂时转向caddy,caddy已经可以支持tls v1.3

更新日志

20180708
OpenSSL于2018年6月8日更新了关于tls 1.3的说明,见此wiki,本文按新wiki修改更新;
主要变化有:OpenSSL目前同时支持“draft-26”, "draft-27" and "draft-28"草案;简化流程,编译时默认开启tls 1.3,无需enable参数;加密算法表达的更新;
Chrome canary 69.0.3484.0 和 Firefox Nightly 63.0a1支持tls1.3 Draft 28。
20180411
Firefox Nightly 61.0a1支持tls1.3 Draft 26。
20180404
IESG批准将TLS 1.3 Draft 28作为TLS version 1.3 的建议标准;
至20180404,Openssl支持的标准为Draft 26。
20180312
Chrome 65正式版已经发布,支持tls1.3 Draft 23。
20180207
修正部分错误。
如果TLSv1.3如期发布,OpenSSL 1.1.1 将于2018年4月17日面向公众发布。对于服务器来说,我还是喜欢CentOS,支持周期很长,折腾一次可以用很长世间,因此以下记录一下在基于LNMP的CentOS 7 系统上启用TLSv1.3的过程。

1 升级系统

yum update

升级后的系统版本为:

cat /etc/centos-release CentOS Linux release 7.5.1804 (Core)

2 安装官方mainline版的nginx

通过官方源安装nginx的目的是:
自动生成nginx的配置文件,减少大量的工作;
获取nginx的编译参数。

配置源:

vi /etc/yum.repos.d/nginx.repo

写入如下内容:

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=0
enabled=1

安装nginx:

yum install nginx -y

查看nginx版本:

nginx -v nginx version: nginx/1.15.1

获取编译参数:

nginx -V nginx version: nginx/1.15.1 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'

修改nginx源,将enabled=1改为enabled=0,防止yum update时nginx被更新掉

vi /etc/yum.repos.d/nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/ gpgcheck=0 enabled=0

3 编译nginx

安装可能用到的依赖:

yum install -y git gcc gcc-c clang automake make autoconf libtool zlib-devel libatomic_ops-devel pcre-devel openssl-devel libxml2-devel libxslt-devel gd-devel GeoIP-devel gperftools-devel  perl-devel perl-ExtUtils-Embed

获取源码:

git clone https://github.com/nginx/nginx.git
git clone https://github.com/openssl/openssl.git
git clone https://github.com/grahamedgecombe/nginx-ct.git

nginx-ct是启用证书透明度(Certificate Transparency)策略的模块。为了启用Certificate Transparency和TLSv1.3,需要额外加入如下编译参数:

--add-module=../nginx-ct/ --with-openssl=../openssl/

加在官方编译参数后面,简单修改形成完整的编译参数:

auto/configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie' --add-module=../nginx-ct/ --with-openssl=../openssl/

进入nginx源码目录,并输入如上完整的编译参数。
开始编译:

make

查看编译好的nginx信息:

./objs/nginx -v nginx version: nginx/1.15.2

备份已经安装好的官方mainline版,安装编译版:

mv /usr/sbin/nginx /usr/sbin/nginx.1.15.1.20180708.official.mainline
cp ./objs/nginx /usr/sbin/

4 修改nginx配置文件内的ssl_protocols和ssl_ciphers,默认启用TLSv1.3的前三项常用的加密算法

...
ssl_protocols          TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
ssl_ciphers            EECDH+CHACHA20:ECDHE+aECDSA+CHACHA20:ECDHE+aRSA+CHACHA20:ECDHE+aECDSA+AESGCM:ECDHE+aRSA+AESGCM:ECDHE+aECDSA+AES256+SHA384:ECDHE+aRSA+AES256+SHA384:ECDHE+aECDSA+AES256+SHA:ECDHE+aRSA+AES256+SHA;
...

重启nginx服务以使修改生效:

systemctl restart nginx

5 测试TLSv1.3是否生效

5.1 使用testssl工具
git clone --depth 1 https://github.com/drwetter/testssl.sh.git
cd testssl.sh
./testssl.sh --help

命令为(coldawn.com需要换成自己的域名):

./testssl.sh -p coldawn.com ... Testing protocols via sockets except SPDY+HTTP2 SSLv2 not offered (OK) SSLv3 not offered (OK) TLS 1 offered TLS 1.1 offered TLS 1.2 offered (OK) TLS 1.3 offered (OK): draft 28, draft 27, draft 26 NPN/SPDY h2, http/1.1 (advertised) ALPN/HTTP2 h2, http/1.1 (offered) ...

详细的情况,用大写的P作为参数:

./testssl.sh -P coldawn.com

 Testing server preferences

 Has server cipher order?     yes (OK)
 Negotiated protocol          TLSv1.3
 Negotiated cipher            TLS_AES_256_GCM_SHA384, 253 bit ECDH (X25519)
 Cipher order
    TLSv1:     ECDHE-RSA-AES256-SHA
    TLSv1.1:   ECDHE-RSA-AES256-SHA
    TLSv1.2:   ECDHE-RSA-CHACHA20-POLY1305 ECDHE-RSA-AES256-GCM-SHA384 ECDHE-RSA-AES128-GCM-SHA256 ECDHE-RSA-AES256-SHA384 ECDHE-RSA-AES256-SHA
    TLSv1.3:   TLS_AES_256_GCM_SHA384 TLS_CHACHA20_POLY1305_SHA256 TLS_AES_128_GCM_SHA256
5.2 使用现代浏览器

Chrome canary 69.0.3484.0 和 Firefox Nightly 63.0a1已经支持tls1.3 Draft 28。

    > Chrome does not currently support Draft 26. You can install Firefox Nightly and already support TLS 1.3 Draft 26.
    Where in the listing is the draft 26 selected?

    So there seems to be already a draft 26, however when I look with git I only see draft 18 and draft 19…?
    Any help is appreciated!

    Thanks. 🙂

    所以似乎已經有了26號草案,但是當我用git看時,我只能看到18號草案和19號草案……?
    任何幫助表示讚賞!

    謝謝。:-)

      The draft 26 is built in nginx by compiled against openssl supporting tls v1.3 draft 26. The version of openssl installed on your server has no effort on it.
      草案26的实现需要将支持draft 26的openssl编译进nginx,它与安装在服务器上的openssl没有关系。

    Cool, you have draft 26 as well… would be nice to know what part of the above source code triggers draft 26?

    Thanks!

    很酷,你還有草案26 …很高興知道上面的源代碼觸發草案26的哪一部分?

    謝謝!

      The testssl.sh tool doesn’t trigger draft 26, but test if a server supports draft 26.
      这个工具并不会触发draft 26,而是检测某网站是否支持draft 26。

      I use caddy for now, which does not support tls 1.3.
      我现在改用caddy了,它现在还不支持tls 1.3。
