Nginx部署

Nginx是一款輕量級(jí)的Web服務(wù)器/反向代理服務(wù)器及電子郵件（IMAP/POP3）代理服務(wù)器。其特點(diǎn)是占有內(nèi)存少，并發(fā)能力強(qiáng)。可以做為EasySwoole的前置服務(wù)器，實(shí)現(xiàn)負(fù)載均衡等。

Dockerfile

FROM centos:8
RUN yum install -y nginx
VOLUME ["/data"]

RUN echo " \
user nginx; \
worker_processes auto; \
error_log /var/log/nginx/error.log; \
pid /run/nginx.pid; \
include /usr/share/nginx/modules/*.conf; \
events { \
    worker_connections 1024; \
} \
http { \
    sendfile            on; \
    tcp_nopush          on; \
    tcp_nodelay         on; \
    keepalive_timeout   65; \
    types_hash_max_size 2048; \
    include             /etc/nginx/mime.types; \
    default_type        application/octet-stream; \
    include /etc/nginx/conf.d/*.conf; \
    include /data/*.conf; \
} " > /etc/nginx/nginx.conf

WORKDIR /hello
RUN cd /hello && echo "hello world" > index.html
RUN echo " \
server { \
    listen 80; \
    server_name _; \
    location / { \
       root /hello; \
    } \
} " > /etc/nginx/conf.d/hello.conf

EXPOSE 80
EXPOSE 443

Docker使用

docker pull easyswoole/nginx
# 啟動(dòng)容器
docker run --privileged -tid -p 80:80 -p 443:443 easyswoole/nginx /usr/sbin/init
# 進(jìn)入容器
docker exec -ti {CONTAINER ID} bash
# 檢查配置文件語法
nginx -t
# 啟動(dòng)nginx 
nginx 
# 停止nginx
nginx -s stop

可以自己啟動(dòng)的時(shí)候-v掛載配置文件目錄到/data ,并可以根據(jù)實(shí)際情況再-v掛載一個(gè)目錄用于存放靜態(tài)文件
