nginx启动的时候报错#yyds干货盘点# _盘点

黄沙百战穿金甲，不破楼兰终不还。这篇文章主要讲述nginx启动的时候报错#yyds干货盘点#相关的知识，希望能为你提供帮助。
问题：

[root@localhost nginx-1.14.2]# /usr/local/nginx/sbin/nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

?遇到这种情况，我们首先得知道，他是因为端口被占用了

第一步：如果我们有iptables，我们就跳过这一步，如果没有则安装?

yum -y install iptables-services
systemctl mask firewalld.service
systemctl enable iptables.services
systemctl enable ip6tables.services

第二步：修改iptables配置文件

vim /etc/sysconfig/iptables添加我们所需要放行的端口
-A INPUT -p tcp -m state --state NEW -m tcp --dport 21 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

【nginx启动的时候报错#yyds干货盘点#】第三步：修改完之后，进行启动
