centos7相关操作
端口操作
（1）查看对外开放的端口状态
查询已开放的端口 netstat -anp
查询指定端口是否已开 firewall-cmd --query-port=666/tcp
提示 yes，表示开启；no表示未开启。
（2）查看防火墙状态
查看防火墙状态 systemctl status firewalld
开启防火墙 systemctl start firewalld
关闭防火墙 systemctl stop firewalld
开启防火墙 service firewalld start
若遇到无法开启
先用：systemctl unmask firewalld.service
然后：systemctl start firewalld.service
添加指定需要开放的端口：
firewall-cmd --add-port=123/tcp --permanent
重载入添加的端口：
firewall-cmd --reload
查询指定端口是否开启成功：
firewall-cmd --query-port=123/tcp
移除指定端口：
firewall-cmd --permanent --remove-port=123/tcp
安装iptables-services ：
yum install iptables-services
进入下面目录进行修改：
/etc/sysconfig/iptables
Centos7 修改启动顺序
查看 启动列表
cat /boot/grub2/grub.cfg |grep menuentry
查看当前默认启动项
grub2-editenv list
修改启动地址
grub2-set-default 'Windows 10'
root管理员用户强制退出其他登录
1 用w命令查看登录用户信息：
# w
2 强制退出marion用户：
# pkill -kill -t pts/1

zookeeper
docker安装zookeeper
1.拉取zookeeper镜像
docker pull wurstmeister/zookeeper
2.运行zookeeper环境
docker run -d --name zookeeper -p 2181:2181 -t wurstmeister/zookeeper
3.进入zookeeper容器
docker exec -it zookeeper /bin/bash
4.切换到bin目录
cd bin
5.查看zookeeper是否启动
./zkServer.sh status
出现 Mode:standalone
则表示成功了，然后输入exit退出即可
kafka
需要先安装zookeeper
1.拉取kafka镜像
docker pull kafka
2.运行kafka环境
docker run --name kafka \
-p 9092:9092 \
-e KAFKA_BROKER_ID=0 \
-e KAFKA_ZOOKEEPER_CONNECT=zookeeper的ip:2181 \
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka的ip:9092 \
-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 \
-d wurstmeister/kafka
第二行是映射的端口
第三行是在kafka集群中，每个kafka都有一个BROKER_ID来区分自己，在这里设置
第四行配置zookeeper管理kafka的路径
第五行把kafka的地址端口注册给zookeeper
第六行配置kafka的监听端口
3.进入kafka容器 docker exec -it kafka /bin/bash
4.创建主题
/opt/kafka/bin/kafka-topics.sh --create --zookeeper zookeeper的ip:2181 --replication-factor 1 --partitions 1 --topic my_log
5.查询创建主题
/opt/kafka/bin/kafka-topics.sh --list --zookeeper zookeeper的ip:2181
