一、创建dockerfile 目录 mkdir -pv /docker/web 二、编写Dockerfile 文件 cd /docker/web vim Dockerfile FROM centos7 MAINTAINER xc 331758730@qq.com COPY CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo COPY nginx_install.sh /tmp/nginx_install.sh RUN sh /tmp/nginx_install.sh RUN sed -i -e '/worker_processes/a daemon off;' /usr/local/nginx/conf/nginx.conf; \rm -rf /opt/nginx* COPY jdk-8u201-linux-x64.tar.gz /opt/jdk-8u201-linux-x64.tar.gz COPY tomcat_install.sh /tmp/tomcat_install.sh RUN sh /tmp/tomcat_install.sh; \rm -rf /opt/* COPY supervisor_install.sh /tmp/supervisor_install.sh COPY supervisord.conf /etc/supervisord.conf COPY start_tomcat.sh /usr/local/tomcat/bin/mystart.sh RUN sh /tmp/supervisor_install.sh; \rm -rf /tmp/*.sh 保存，退出。 三、准备文件：（文件都放在/docker/web/ 里面） cd /docker/web vim nginx_install.sh #!/bin/bash yum install gcc gcc-c++ wget tar vim net-tools pcre pcre-devel openssl openssl-devel -y useradd -s /sbin/nologin nginx cd /opt wget http://www.xchinagroup.top/softdown/centos7/02_nginx/nginx-1.15.9.tar.gz tar zxf nginx-1.15.9.tar.gz cd nginx-1.15.9/ ./configure --with-http_ssl_module --with-http_stub_status_module --with-stream --prefix=/usr/local/nginx/ make make install ++++++++++++++++++++++++++++++++++++++++++++++++++++++ tomcat 安装脚本：tomcat_install.sh #!/bin/bash cd /opt/ tar zxf jdk-8u201-linux-x64.tar.gz -C /usr/local/ echo 'export JAVA_HOME=/usr/local/jdk1.8.0_201/' >>/etc/profile echo 'export PATH=$PATH:$JAVA_HOME/bin' >>/etc/profile echo 'export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH' >>/etc/profile source /etc/profile wget http://www.xchinagroup.top/softdown/centos7/16_docker/apache-tomcat-9.0.20.tar.gz tar zxf apache-tomcat-9.0.20.tar.gz mv apache-tomcat-9.0.20 /usr/local/tomcat ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ supervisor 安装脚本： vim supervisor_install.sh yum -y install epel-release yum -y install python2-pip pip install supervisor ++++++++++++++++++++++++++++++++++++++++++++++++++++++ supervisor配置文件： vim supervisord.conf [unix_http_server] file=/tmp/supervisor.sock ; the path to the socket file [supervisord] logfile=/tmp/supervisord.log ; 日志 logfile_maxbytes=50MB ; 最大50M日志 logfile_backups=10 ; 轮循日志备份10个 loglevel=info ; 日志等级记录info的 pidfile=/tmp/supervisord.pid ;pid nodaemon=true ;在前台启动 minfds=102400 ; 文件描述符限制 minprocs=2000 ; 进程数 [rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface [supervisorctl] serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL for a unix socket [program:nginx] command=/usr/local/nginx/sbin/nginx ; 前台启动nginx autostart=true ; 随着supervisor自动启动 startsecs=10 ; 启动10s后算正常启动 autorestart=true ; 程序退出后自动重启 startretries=3 ; 启动失败自动重试次数 stdout_logfile_maxbytes=20MB ;stdout 日志文件大小最大20Mb stdout_logfile=/usr/local/nginx/logs/out.log [program:tomcat] command=sh /usr/local/tomcat/bin/mystart.sh ; 前台启动tomcat autostart=true ; 随着supervisor自动启动 startsecs=10 ; 启动10s后算正常启动 autorestart=true ; 程序退出后自动重启 startretries=3 ; 启动失败自动重试次数 stdout_logfile_maxbytes=20MB ;stdout 日志文件大小最大20Mb stdout_logfile=/usr/local/tomcat/logs/catalina.out ++++++++++++++++++++++++++++++++++++++++++++++++++++ yum 源文件：CentOS-Base.repo vim CentOS-Base.repo [base] name=CentOS-$releasever - Base baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ JDK文件：jdk-8u201-linux-x64.tar.gz 这个文件比较大，先下载到/docker/web/ 里面 wget http://www.xchinagroup.top/softdown/centos7/16_docker/ jdk-8u201-linux-x64.tar.gz +++++++++++++++++++++++++++++++++++++++++++++++++++++ Tomcat 启动脚本文件：start_tomcat.sh vim start_tomcat.sh source /etc/profile /usr/local/tomcat/bin/catalina.sh run ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ /docker/web/ 里面，应该有如下文件。四、构建nginx + tomcat cd /docker/web docker build -t nginx_tomcat .
查看镜像：docker images
启动镜像： docker run -d nginx_tomcat /bin/bash -c 'supervisord -c /etc/supervisord.conf'
查看进程： ps auxfww
查看nginx tomcat 端口 、进程
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ####：关于进入容器出现：bash: /opt/app-root/etc/scl_enable: No such file or directory 直接在Dockerfile文件中添加如下内容： RUN mkdir -p /opt/app-root/etc/; \echo "unset BASH_ENV PROMPT_COMMAND ENV" >>/opt/app-root/etc/scl_enable ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
docker build -t nginx_tomcat_01 .
docker run -d nginx_tomcat_01 /bin/bash -c 'supervisord -c /etc/supervisord.conf'
