nginx - 构建nginx docker时出错

Question

我正在尝试从 fork 构建一个 docker，但在执行 docker build ./ 时收到以下错误:

cc1: all warnings being treated as errors
make[1]: *** [objs/src/event/ngx_event_openssl.o] Error 1
objs/Makefile:748: recipe for target 'objs/src/event/ngx_event_openssl.o' failed
make[1]: Leaving directory '/tmp/nginx/nginx-1.8.0'
make: *** [install] Error 2

安装时我们运行

apt-get -y install libpcre3-dev zlib1g-dev libssl-dev openssl build-essential wget

我在谷歌上找不到这个错误。完整的错误供引用，因为我无法找到我需要研究的确切错误引用:

这是我正在运行的 docker fork https://github.com/meteorhacks/mup-frontend-server

您在这里收到各种错误和警告，但它们实际上与 Docker 或 OpenSSL 无关。如果我们去掉无关信息，这就是您遇到的问题。

error: 'OPENSSL_config' is deprecated
error: 'RSA_generate_key' is deprecated
error: dereferencing pointer to incomplete type 'DH {aka struct dh_st}'
error: dereferencing pointer to incomplete type 'SSL {aka struct ssl_st}'
error: 'SSL_R_NO_CIPHERS_PASSED' undeclared (first use in this function)
error: passing argument 2 of 'SSL_CTX_sess_set_get_cb' from incompatible pointer type
error: storage size of 'md' isn't known
error: implicit declaration of function 'EVP_MD_CTX_cleanup'
error: 'RAND_pseudo_bytes' is deprecated

这里问题的核心可能是您在这个项目中使用了旧版本的 Nginx。从您指向的 GitHub 存储库中的 install-nginx.sh 中:

NGINX_VERSION=1.8.0

Nginx 当前的主线版本是 1.13.2。我还没有梳理 Nginx 的变更日志，但根据您收到的错误，似乎在 1.8 版本和当前版本之间，OpenSSL 已经弃用了 Nginx 1.8 所依赖的各种功能。这很可能可以通过迁移到 Nginx 的最新版本来解决。

截至撰写本文时，1.13.2 是当前主线，1.12.0 是当前稳定版本。其中之一可能效果更好。我不能说你是否可以简单地把它放进去。您可能需要更改构建脚本或 nginx 配置中的某些内容才能使更新版本正常工作。
