前言
为什么要使用openresty?
官方说明:OpenResty® 是一个基于 Nginx 与 Lua 的高性能 Web 平台,其内部集成了大量精良的 Lua 库、第三方模块以及大多数的依赖项。所以。
但openresty官方没有发布docker相关东西,所以以:结合openresty安装、参考docker-nginx官方的为原则编写。
1.依赖安装测试
官方声明依赖:perl 5.6.1+, libpcre, libssl
a.按nginx镜像测试
# perl查找
/ # apk search perl5
perl-5.26.3-r0 #就一个可选
/ # apk search libpcre
libpcre2-32-10.32-r1 #貌似最新版本了,32位的?
pcre-dev-8.42-r1
libpcre2-16-10.32-r1
pcre2-dev-10.32-r1
libpcre16-8.42-r1
libpcre32-8.42-r1
pcre2-10.32-r1
pcre-8.42-r1
libpcrecpp-8.42-r1
/ # apk search libssl
openssl-dev-1.1.1b-r1
libressl-dev-2.7.5-r0 #看起来最合适
nss-3.41-r0
libssl1.1-1.1.1b-r1
dovecot-2.3.6-r0
libressl2.7-libssl-2.7.5-r0
/ # apk add perl-5.26.3-r0 libpcre2-32-10.32-r1 libressl-dev-2.7.5-r0
# 完全报错,这个alpine依赖搞不了,官方https://pkgs.alpinelinux.org/包的搜索页捉襟见肘,不得不放弃“小而美”。
b.容器测试
参考官方选则debian,github上构建平台镜像的许多镜像选择stretch-slim精简版的,看下大小最新的只有55.3M,比较满意。
环境安装测试:
[]:~/tmp/dk/openresty# docker run -itd --name df -v /root/tmp/dk/openresty:/tmp/host debian:stretch-slim
[]:~/tmp/dk/openresty# docker exec df -it /bin/bash
初始安装清华源,切换百度源(云本机),apt-get update超慢,后回归官源,后期卡死用网易源。
问题:
1、./configure: error: ngx_postgres addon was unable to detect version of the libpq library.
apt-get libpq-dev -y
2、./configure: error: the HTTP gzip module requires the zlib library.
apt-get install openssl libssl-dev libperl-dev -y
apt-get install zlib1g-dev -y
到此OK。

VOLUME ["/etc/nginx","/var/www/html"]
EXPOSE 80
STOPSIGNAL SIGTERM
# CMD ["nginx", "-g", "daemon off;"] #注意官方提示
2.运行测试
准备配置数据(之前旧配置),注意 html和nginx文件夹 的参数共享:
[]:~/tmp/dk/openresty# tree ./
./
├── config
│ ├── conf.d
│ │ └── nginx.vh.default.conf
│ │ └── vhost.conf
│ └── nginx.conf
└── html
a.测试启动
测试容器df(手动搭建,系统无法ps),运行正常:
root@df08a646aaa0:/# nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
但Dockerfile所建镜像的容器启动关闭无日志,更换openresty官方配置:
[]:~/tmp/dk/openresty# docker run -itd --name n1 -v /root/tmp/dk/openresty/config:/etc/nginx \
-v /root/tmp/dk/openresty/html:/var/www/html cffycls/openresty:0.9 \
/usrl/ocal/openresty/nginx/sbin/nginx
#无法启动,容器运行终止,无日志。应该是配置文件问题
b.修改配置文件
使用官方原包未修改:
# 官包解压路径:./bundle/nginx-1.15.8/conf/nginx.conf
[]:~/tmp/dk/openresty# tree conf
conf
├── fastcgi.conf
├── fastcgi_params
├── koi-utf
├── koi-win
├── mime.types
├── nginx.conf
├── scgi_params
├── uwsgi_params
└── win-utf
去掉run加的命令,加上端口,运行Up了。
c.运行测试
CMD ["/usrl/ocal/openresty/nginx/sbin/nginx", "-g", "daemon off;"]
[]:~/tmp/dk/openresty# docker run -itd --name n1 -p 80:80 \
-v /root/tmp/dk/openresty/conf:/usrl/ocal/openresty/nginx/conf \
-v /root/tmp/dk/openresty/html:/usrl/ocal/openresty/nginx/html \
openresty/openresty:1.0
运行成功,大小357M,太大了感觉,提交到云端。
3.启动官方镜像
提交到云端,偶然想搜索下有没有,docker-hub竟然(反问)有官方镜像,pull了个下来,144M还不错。真是重复造轮子了!!!
折腾半天,算是个教训了,算是测得到了运行方法,结果也还行。
[]:~/tmp/dk/openresty# docker run -itd --name n1 -p 80:80 \
-v /root/tmp/dk/openresty/conf:/usrl/local/openresty/nginx/conf \
-v /root/tmp/dk/openresty/html:/usr/local/openresty/nginx/html \
openresty/openresty
访问web端正常。
