阿里云开放端口

二、CentOs 7 防火墙开放端口

  1. 查看正在监听的端口和进程信息:

netstat -ntlp

可以看到tomcat/java、nginx、redis、 mysql等进程正在监听的端口,这些接口都需要通过阿里云安全组以及防火墙同时开启接口才能生效,截图如下:

  1. 以开放80端口为例:

开放端口:firewall-cmd --zone=public --add-port=80/tcp --permanent

重启防火墙:systemctl restart firewalld.service

查看已开启的端口信息:

firewall-cmd --list-ports

  1. 防火墙常用命令:

查看防火墙状态,running代表正在运行:
firewall-cmd --state

停止命令

systemctl stop firewalld.service
启动命令
systemctl start firewalld.service
重启命令
systemctl restart firewalld.service

# 查看已经开放的端口
firewall-cmd --zone=public --list-ports
firewall-cmd --list-ports
# 查询指定端口是否已开
sudo firewall-cmd --query-port=8081/tcp
# 开放端口
firewall-cmd --zone=public --add-port=9001/tcp # --permanent 永久生效
# 关闭端口
firewall-cmd --permanent --zone=public --remove-port=22/tcp
# 重启防火墙生效
service firewalld.service restart

解读telnet命令探测端口是否开放用法

https://developer.aliyun.com/article/583263

[root@localhost ~]# telnet 61.135.169.125 80
Trying 61.135.169.125…
Connected to 61.135.169.125 (61.135.169.125).
Escape character is’^]'.
是的,如上显示,这就说明这个地址的80端口是开放的,很简单吧 //进入这个状态,需要按ctrl+c退出即可

注明:安装之前检测系统是否有自带的 MySQL。

rpm -qa | grep mysql # 检查是否安装过 MySQL
rpm -qa | grep mariadb # 检查是否存在 mariadb 数据库(内置的 MySQL 数据库),有则强制删除
rpm -e --nodeps mariadb-libs-5.5.68-1.el7.x86_64 # 强制删除
rpm -e --nodeps mariadb-5.5.68-1.el7.x86_64 # 强制删除
