Nginx Compose
创建DockerCompose项目目录
mkdir compose_nginx_tomcat
cd compose_nginx_tomcat/
mkdir nginx
cd nginx
wget -c https://nginx.org/download/nginx-1.12.2.tar.gz
vi Dockerfile
## 指定镜像
FROM debian:stretch-slim
#FROM centos:6
# 指定管理员
MAINTAINER linuxsa.org
# 执行命令安装编译库文件
RUN apt update && apt install -y gcc gcc g++ make openssl libssl-dev libpcre3 libpcre3-dev
#RUN yum install -y gcc gcc-c++ make openssl-devel pcre-devel
# RUN apt-get update && apt-get install -y --no-install-recommends g++ gcc libc6-dev make && rm -rf /var/lib/apt/lists*
# 添加解压nginx包到/tmp目录下
RUN mkdir -p /tmp
ADD nginx-1.12.2.tar.gz /tmp
# 不用什么tar 解压 ,进入目录进行编译安装
RUN cd /tmp/nginx-1.12.2 && ./configure --prefix=/usr/local/nginx --without-http_gzip_module && make -j 2 && make install
# 删除容器内置配置文件
RUN rm -f /usr/local/nginx/conf/nginx.conf
# 复制本地配置文件到容器内
COPY nginx.conf /usr/local/nginx/conf
# 声明暴露端口
EXPOSE 80
# 启动容器Nginx服务，指定全局命令daemon off保证服务在前台运行不会关闭
CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]

创建Mysql Compose
2.1、创建Mysql管理目录 mkdir mysql mkdir mysql/data cd mysql mkdir conf cd conf 2.2、创建mysql配置文件 vi my.cnf #要优化 [mysqld] user=mysql port=3306 datadir=/var/lib/mysql socket=/var/run/mysqld/mysqld.sock pid-file=/var/run/mysqld/mysqld.pid log_error=/var/log/mysql/error.log character_set_server = utf8 max_connections=3600
创建Tomcat Compose
3.1、创建tomcat管理目录与网站目录 mkdir tomcat mkdir -p webapps/ROOT/ cd tomcat 3.2、下载tomcat、jdk 压缩文件下载到本地 [root@work2 tomcat]# pwd /root/compose_nginx_tomcat/tomcat [root@work2 tomcat]# ls apache-tomcat-8.5.42.tar.gz Dockerfile jdk-8u211-linux-x64.tar.gz server.xml 3.3 创建Dockerfile文件 vi Dockerfile FROM debian:stretch-slim # 指定管理员 MAINTAINER linuxsa.org # 解压jdk包到指定目录 ADD jdk-8u211-linux-x64.tar.gz /usr/local # 安装jdk包到指定目录 ENV JAVA_HOME /usr/local/jdk1.8.0_211 # 解压tomcat包到指定目录 ADD apache-tomcat-8.5.42.tar.gz /usr/local # 将本地配置文件复制到镜像内 COPY server.xml /usr/local/apache-tomcat-8.5.42/conf # 指定服务暴露端口 EXPOSE 8080 # 启动tomcat服务 ENTRYPOINT ["/usr/local/apache-tomcat-8.5.42/bin/catalina.sh", "run"]
3.4 创建server.xml配置文件
vi server.xml
<?xml version='1.0' encoding='utf-8'?>
