CentOS7使用yum安装Nginx(防火墙未放行80端口解决)

CentOS7使用yum安装Nginx

添加Nginx到YUM源

sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

安装Nginx

sudo yum install -y nginx

启动Nginx

sudo systemctl start nginx.service

如果一切正常,打开浏览器应该能访问到默认的Welcome页面,出现打开不了的情况,那多半是因为网络防火墙没有放开80端口。下面是解决办法(如果没遇到不能访问默认页面可自行往下查看设置开机自启部分)

查看Nginx是否已经运行成功

[root@localhost home]# ps aux|grep nginx root 36612 0.0 0.0 46464 972 ? Ss 19:49 0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf nginx 36613 0.0 0.1 46856 1604 ? S 19:49 0:00 nginx: worker process root 39654 0.0 0.0 112824 980 pts/0 S+ 19:53 0:00 grep --color=auto nginx

查看端口80是否分配给Nginx

[root@localhost \]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 36612/nginx: master tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1091/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1272/master tcp6 0 0 :::22 :::* LISTEN 1091/sshd tcp6 0 0 ::1:25 :::* LISTEN 1272/master

解决办法

第一步,对80端口进行防火墙配置:

[root@localhost home]# firewall-cmd --zone=public --add-port=80/tcp --permanent

第二步,重启防火墙服务:

systemctl restart firewalld.service

设置Nginx开机自启

sudo systemctl enable nginx.service
