Dockerfile-NGINX鏡像制作

1 NGINX鏡像制作:

1.1 NGINX-dockerfile

FROM centos:7
LABEL maintainer www.chenleilei.net
RUN useradd  www -u 1200 -M -s /sbin/nologin
RUN mkdir -p /var/log/nginx
RUN yum install -y cmake pcre pcre-devel openssl openssl-devel gd-devel \
    zlib-devel gcc gcc-c++ net-tools iproute telnet wget curl &&\
    yum clean all && \
    rm -rf /var/cache/yum/*
RUN wget https://www.chenleilei.net/soft/nginx-1.16.1.tar.gz
RUN tar xf nginx-1.16.1.tar.gz
WORKDIR nginx-1.16.1
RUN ./configure --prefix=/usr/local/nginx --with-http_image_filter_module --user=www --group=www \
    --with-http_ssl_module --with-http_v2_module --with-http_stub_status_module \
    --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log \
    --pid-path=/var/run/nginx/nginx.pid
RUN make -j 4 && make install && \
    rm -rf /usr/local/nginx/html/*  && \
    echo "leilei hello" >/usr/local/nginx/html/index.html  && \
    rm -rf nginx* && \
    ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\
    ln -sf /dev/stdout /var/log/nginx/access.log && \
    ln -sf /dev/stderr /var/log/nginx/error.log
RUN chown -R www.www /var/log/nginx
ENV LOG_DIR /var/log/nginx
ENV PATH $PATH:/usr/local/nginx/sbin
#COPY nginx.conf /usr/local/nginx/conf/nginx.conf
EXPOSE 80
WORKDIR /usr/local/nginx
CMD ["nginx","-g","daemon off;"]

案例2:

FROM centos:7
LABEL maintainer www.chenleilei.net
RUN yum install -y openssl && \
useradd  www -u 1000 -M -s /sbin/nologin && \
rm -fr /etc/yum.repos.d/* && \
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm && yum clean all && \
yum install -y nginx-1.18.0-2.el7.ngx.x86_64  &&  yum clean all &&  rm -rf /var/cache/yum/* && \
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
ln -sf /dev/stdout /var/log/nginx/access.log && \
ln -sf /dev/stderr /var/log/nginx/error.log && \
sed -i "1,3s#nginx#www#g" /etc/nginx/nginx.conf
EXPOSE 80
EXPOSE 443
WORKDIR /etc/nginx
CMD ["nginx","-g","daemon off;"]

1.2 啟動nginx

 保存為: dockerfile-nginx
 docker build -t nginx-v001 -f nginx-dockerfile .
 useradd  www -u 1200 -M -s /sbin/nologin
 
 mkdir /www -p
 docker run --name nginx-v001 -d -p 80:80 -v /www:/usr/local/nginx/html -v /var/log/nginx:/var/log/nginx --restart=always --privileged=true  nginx-v001

'啟動時將目錄掛載到本地,以供php程序進行調用解析.' 


### 1.3 可選: (配置PHP解析)
 進入nginx配置文件修改php解析:
 /usr/local/nginx/conf/nginx.conf
 
 location ~ \.php$ {
    root           html;
    fastcgi_pass   172.17.0.2:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
    include        fastcgi_params;
}

#如何獲取php容器IP地址:
 docker inspect php-v001|grep IPAdd
 --------------------------------------------------------
 [root@master docker-file]# docker inspect php-v001|grep IPAdd
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2"
                    
 從這里可以看到php服務的容器地址: 172.17.0.2   ,將nginx配置文件種的php解析修改為:172.17.0.2 
 網頁目錄默認為: /usr/local/nginx/html
 
 配置完成重啟nginx.
