# ls /opt nginx-server nginx-server-port

在宿主机上访问
# docker top nginx-server-port UID PID PPID C STIME TTY TIME CMD root 2219522163015:08 ? 00:00:00 nginx: master process nginx -g daemon off; 1012238722195015:08 ? 00:00:00 nginx: worker process

三、使用Docker容器实现Tomcat部署
3.1 获取参考资料
3.2 运行tomcat应用容器
3.2.1 不暴露端口运行
# docker run -d --rm tomcat:9.0
# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES c20a0e781246 tomcat:9.0"catalina.sh run"27 seconds ago Up 25 seconds 8080/tcp heuristic_cori
3.2.2 暴露端口运行
# docker run -d -p 8080:8080 --rm tomcat:9.0 2fcf5762314373c824928490b871138a01a94abedd7e6814ad5f361d09fbe1de
# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 2fcf57623143 tomcat:9.0"catalina.sh run"3 seconds ago Up 1 second 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp eloquent_chatelet
在宿主机访问
# docker exec 2fc ls /usr/local/tomcat/webapps 里面为空，所以可以添加网站文件。
3.2.3 暴露端口及添加网站文件
# docker run -d -p 8081:8080 -v /opt/tomcat-server:/usr/local/tomcat/webapps/ROOT tomcat:9.0 f456e705d48fc603b7243a435f0edd6284558c194e105d87befff2dccddc0b63

7.4 Redis集群
安装redis-cluster；3主3从方式，从为了同步备份，主进行slot数据分片
编辑运行多个redis容器脚本文件 # vim redis-cluster.sh # cat redis-cluster.sh for port in$(seq 80018006); \ do \ mkdir -p /mydata/redis/node-${port}/conf touch /mydata/redis/node-${port}/conf/redis.conf cat << EOF >/mydata/redis/node-${port}/conf/redis.conf port ${port} cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout5000 cluster-announce-ip192.168.255.157 cluster-announce-port${port} cluster-announce-bus-port1${port} appendonly yes EOF docker run -p${port}:${port} -p1${port}:1${port} --name redis-${port} \ -v /mydata/redis/node-${port}/data:/data \ -v /mydata/redis/node-${port}/conf/redis.conf:/etc/redis/redis.conf \ -d redis:5.0.7 redis-server /etc/redis/redis.conf; \ done
