sudo yum install -y nginx 启动并设置为开机启动 基本指令: sudo systemctl start nginx.service sudo systemctl enable nginx.service sudo systemctl status nginx.service sudo systemctl restart nginx.service 查看版本,确认启动 nginx -v nginx version: nginx/1.12.2 ps -ef |grep nginx 测试网站配置 sudo nginx -t curl 127.0.0.1

1. 检查 nginx 配置文件 sudo vim /etc/nginx/nginx.conf 内容摘要以下: server { listen 80 default_server; listen [::]:80 default_server; server_name _; root /usr/share/nginx/html; .... # Load modular configuration files from the /etc/nginx/conf.d directory. # See http://nginx.org/en/docs/ngx_core_module.html#include # for more information. include /etc/nginx/conf.d/*.conf; 配置网站模块放在 /etc/nginx/conf.d/*.conf 下 2. 新建一个网站 : chuangke.conf sudo touch /etc/nginx/conf.d sudo vim chuangke.conf 加入如下内容 server { listen 8080; server_name 127.0.0.1; root /usr/share/nginx/chuangke; # root /var/www/chuangke; index index.html; location / { } } 测试一下配置 sudo nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful 重启 nginx sudo systemctl restart nginx 测试网站 curl 127.0.0.1:8080 使用 root /var/www/chuangke 老是 403 错误?! <html> <head><title>403 Forbidden</title></head> <body bgcolor="white"> <center><h1>403 Forbidden</h1></center> <hr><center>nginx/1.12.2</center> </body> </html>
1. 查看防火墙状态 sudo systemctl status firewalld sudo firewall-cmd --state running 2. 防火墙基本命令 # 开启 service firewalld start # 重启 service firewalld restart # 关闭 sudo service firewalld stop # 查看防火墙规则 sudo firewall-cmd --list-all sudo firewall-cmd --state 3. 开启 8080 端口 sudo firewall-cmd --zone=public --add-port=8080/tcp --permanent 重启防火墙 sudo systemctl restart firewalld.service sudo firewall-cmd --reload 4. 不知道为何,就把本身关在外面了 ssh 链接不上去了! sudo firewall-cmd --list-all public (active) target: default icmp-block-inversion: no interfaces: enp0s3 sources: services: ssh dhcpv6-client ports: protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules: ** 能够看到,ports 一个都没有! ** 干脆从新增长端口的时候,先加上 20,22 端口 sudo firewall-cmd --zone=public --add-port=80/tcp --permanent sudo firewall-cmd --zone=public --add-port=22/tcp --permanent sudo firewall-cmd --zone=public --add-port=21/tcp --permanent sudo firewall-cmd --zone=public --add-port=20/tcp --permanent sudo firewall-cmd --zone=public --add-port=8080/tcp --permanent sudo firewall-cmd --zone=public --add-port=4433/tcp --permanent 重启防火墙 sudo systemctl restart firewalld.service 从新查看防火墙规则 sudo firewall-cmd --list-all public (active) target: default icmp-block-inversion: no interfaces: enp0s3 sources: services: ssh dhcpv6-client ports: 80/tcp 22/tcp 21/tcp 20/tcp 8080/tcp 4433/tcp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules: ** 如今能够安全的退出、从新 ssh 了!
1. 测试:将以上 chuangke.conf 的端口改为 4433后 sudo systemctl restart nginx 返回错误! Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details. 2. 测试 nginx 配置是 OK! sudo nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful 3. 查看错误信息 sudo systemctl status nginx.service ...... 3月 29 15:07:26 centos7-71 nginx[18289]: nginx: [emerg] bind() to 0.0.0.0:4433 failed (13: Permission denied) ...... 3月 29 15:07:26 centos7-71 systemd[1]: Unit nginx.service entered failed state. 3月 29 15:07:26 centos7-71 systemd[1]: nginx.service failed.
** 4433 端口不容许!python

1. 直接安装 semanage 会提示:没有 semanage sudo yum update sudo yum install semanage 已加载插件:fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com 没有可用软件包 semanage。 错误:无须任何处理 2. 按照参考文档,执行一下设置和安装命令 1). yum provides /usr/sbin/semanage 2). yum -y install policycoreutils-python 3). 如今就能够执行 semanage 命令了 3. 查看 http 能够访问的端口 sudo semanage port -l | grep http_port_t http_port_t tcp 80, 81, 443, 488, 8008, 8009, 8443, 9000 pegasus_http_port_t tcp 5988 ** 果真没有发现 4433 端口! 4. 增长 4433 到 http 访问端口 sudo semanage port -a -t http_port_t -p tcp 4433 5. 再来看看 http 端口 sudo semanage port -l | grep http_port_t http_port_t tcp 4433, 80, 81, 443, 488, 8008, 8009, 8443, 9000 pegasus_http_port_t tcp 5988 ** 如今能够访问 4433 了 sudo systemctl restart nginx sudo systemctl status nginx.service OK!
不是简单从防火墙开放一个端口就能够了 还要配置 特定服务(此次是 HTTP)可使用哪些端口nginx

实在没有办法了! 只好先关闭 SELinux !之后再学习! sudo vim /etc/selinux/config # by wzh 20190329 disable SELINUX SELINUX=disabled # SELINUX=enforcing 重启才能生效! 查看 SELinux sestatus SELinux status: disabled
