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

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

# 2、直接进入数据库,母机安装mysql client 但是不要安装mysql service 
mysql -h192.168.88.22 -uroot -p123456

浏览器测试nginx代理tomcat

打开浏览器

# 1、进入nginx管理界面
docker container exec -it e7c9152c93ac /bin/bash

修改Docker配置文件/etc/default/docker如下：

DOCKER_OPTS="--registry-mirror=http://aad0405c.m.daocloud.io"
使用service docker restart重启Docker服务即可。

现在使用docker pull拉取镜像真是特别爽，速度很快，再次感谢DaoCloud公司
