CentOS rpm安装Nginx和配置

官方下载地址: http://nginx.org/en/download.html

介绍

Nginx(“engine x”)是一款由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和 反向代理 服务器,也是一个 IMAP/POP3/SMTP 代理服务器。

rpm包安装

#安装nginx,rpm安装
#rpm安装nginx包
rpm -Uvh --force --nodeps nginx-1.16.1-1.el7.ngx.x86_64.rpm

#查看启动状态
systemctl status nginx

显示如下:

#启动
systemctl start nginx

#重启
systemctl restart nginx

#开机自启动服务
systemctl enable nginx

#查看开机启动状态 enabled:开启, disabled:关闭
systemctl is-enabled nginx

安装完后在 修改 /etc/nginx/conf.d/default.conf 配置文件,参考内容如下:

vim /etc/nginx/conf.d/default.conf
server {
listen   80;
server_name  localhost;

#charset koi8-r;
#access_log  /var/log/nginx/host.access.log  main;


 location /ui {
alias   /data/dist;
index  index.html index.htm;
 }
 
 location /file/ {
 root   /home/data/;
index  index.html index.htm;
 }
# websocket配置wss
location /liangws/ {
proxy_pass http://192.168.0.19:8080/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection \"upgrade\";
proxy_set_header Remote_addr $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_read_timeout 600s;
}

location ~ /gat {
proxy_set_header Host  $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://localhost:18080 ;
}

#error_page  404  /404.html;

# redirect server error pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   /usr/share/nginx/html;
}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \\.php$ {
#proxy_pass   http://127.0.0.1;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \\.php$ {
#root   html;
#fastcgi_pass   127.0.0.1:9000;
#fastcgi_index  index.php;
#fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
#includefastcgi_params;
#}

# deny access to .htaccess files, if Apache\'s document root
# concurs with nginx\'s one
#
#location ~ /\\.ht {
#deny  all;
#}
}

注意:静态文件下载,需要依赖nginx,我们需要将这些文件放到 nginx配置文件中的 /home/data/aaa 对应的目录下。
