我要评论一、nginx 下载
从官网中下载 nginx 压缩包到本地（http://nginx.org/en/download.html）
二、部署步骤
- 在 /usr/local 目录下新建 nginx 文件夹
[root@izwz9cwntagbp2m20emj0qz local]# mkdir nginx [root@izwz9cwntagbp2m20emj0qz local]# ls aegis app bin etc games include lib lib64 libexec nginx sbin share src
- 将 nginx 压缩包使用 sftp 上传到 linux 系统的 /usr/local/nginx 目录下
[root@izwz9cwntagbp2m20emj0qz nginx]# ls nginx-1.22.1.tar.gz
- 解压 nginx-1.22.1.tar.gz
[root@izwz9cwntagbp2m20emj0qz nginx]# tar -zxvf nginx-1.22.1.tar.gz nginx-1.22.1/ nginx-1.22.1/auto/ ...... [root@izwz9cwntagbp2m20emj0qz nginx]# ls nginx-1.22.1 nginx-1.22.1.tar.gz
- 进入 nginx，找到 configure
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/nginx-1.22.1/ [root@izwz9cwntagbp2m20emj0qz nginx-1.22.1]# ls auto changes changes.ru conf configure contrib html license makefile man objs readme src
- 运行 configure，命令 ./configure
[root@izwz9cwntagbp2m20emj0qz nginx-1.22.1]# ./configure
①如果报错执行yum -y install pcre-devel // 安装pore
②如果再次报错执行 yum -y install openssl openssl-devel //安装openssl
- 编译 nginx 文件
[root@izwz9cwntagbp2m20emj0qz nginx-1.22.1]# make [root@izwz9cwntagbp2m20emj0qz nginx-1.22.1]# make install
- 检查是否安装成功
[root@izwz9cwntagbp2m20emj0qz nginx-1.22.1]# whereis nginx nginx: /usr/local/nginx
- 找到 ngingx 的 sbin 目录
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/ [root@izwz9cwntagbp2m20emj0qz nginx]# ll total 1092 drwx------ 2 nobody root 4096 mar 14 11:39 client_body_temp drwxr-xr-x 2 root root 4096 mar 14 14:31 conf drwx------ 2 nobody root 4096 mar 14 11:39 fastcgi_temp drwxr-xr-x 2 root root 4096 mar 14 11:37 html drwxr-xr-x 2 root root 4096 mar 14 14:37 logs drwxr-xr-x 9 1001 1001 4096 mar 14 11:33 nginx-1.22.1 -rw-r--r-- 1 root root 1073948 mar 14 11:19 nginx-1.22.1.tar.gz drwx------ 2 nobody root 4096 mar 14 11:39 proxy_temp drwxr-xr-x 2 root root 4096 mar 14 11:37 sbin drwx------ 2 nobody root 4096 mar 14 11:39 scgi_temp drwx------ 2 nobody root 4096 mar 14 11:39 uwsgi_temp [root@izwz9cwntagbp2m20emj0qz nginx]# cd sbin/
- 启动 nginx
[root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx
- 访问测试
三、演示修改 nginx 配置，修改端口号
- 找到 /conf 目录下的 nginx.conf 配置文件
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/nginx-1.22.1/conf/ [root@izwz9cwntagbp2m20emj0qz conf]# ll total 40 -rw-r--r-- 1 1001 1001 1077 oct 19 16:02 fastcgi.conf -rw-r--r-- 1 1001 1001 1007 oct 19 16:02 fastcgi_params -rw-r--r-- 1 1001 1001 2837 oct 19 16:02 koi-utf -rw-r--r-- 1 1001 1001 2223 oct 19 16:02 koi-win -rw-r--r-- 1 1001 1001 5349 oct 19 16:02 mime.types -rw-r--r-- 1 1001 1001 2656 oct 19 16:02 nginx.conf -rw-r--r-- 1 1001 1001 636 oct 19 16:02 scgi_params -rw-r--r-- 1 1001 1001 664 oct 19 16:02 uwsgi_params -rw-r--r-- 1 1001 1001 3610 oct 19 16:02 win-utf
- 使用 vim 编辑 nginx.conf 文件
[root@izwz9cwntagbp2m20emj0qz conf]# vim nginx.conf
修改监听端口为666
server {
listen 666;
server_name localhost;
}
保存并退出：esc -> shift + : -> wq
3. 重新加载 nginx.conf 配置文件
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/sbin/ [root@izwz9cwntagbp2m20emj0qz sbin]# ll total 3804 -rwxr-xr-x 1 root root 3892016 mar 14 11:37 nginx [root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx -s reload
- 测试端口修改是否成功
四、使用 nginx 转发访问后端服务
- 启动 spring boot 项目
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/app/
[root@izwz9cwntagbp2m20emj0qz app]# ll
total 16160
-rw-r--r-- 1 root root 16546230 mar 14 14:23 springboot-0.0.1-snapshot.jar
[root@izwz9cwntagbp2m20emj0qz app]# java -jar springboot-0.0.1-snapshot.jar

在浏览器中测试访问接口
在 nginx.conf 文件中配置 location
[root@izwz9cwntagbp2m20emj0qz ~]# cd /
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/nginx-1.22.1/conf/
[root@izwz9cwntagbp2m20emj0qz conf]# vim nginx.conf
server {
listen 80;
server_name localhost;
location /json/ {
proxy_pass http://112.74.190.252:666/json/;
}
}
- 重新加载 nginx.conf 配置文件
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/sbin/ [root@izwz9cwntagbp2m20emj0qz sbin]# ll total 3804 -rwxr-xr-x 1 root root 3892016 mar 14 11:37 nginx [root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx -s reload
- 浏览器中测试（使用 nginx 监听的 80 端口访问）
五、nginx 常用命令
- 查看 nginx 位置
[root@izwz9cwntagbp2m20emj0qz /]# whereis nginx nginx: /usr/local/nginx
- 启动 nginx
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/sbin/ [root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx
- 停止 nginx
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/sbin/ [root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx -s stop
- 安全退出 nginx
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/sbin/ [root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx -s quit
- 重新加载配置文件
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/sbin/ [root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx -s reload
(注意：nginx 启动、停止、退出、重新加载命令都需要在 sbin 目录下执行)
- 查看 nginx 进程
[root@izwz9cwntagbp2m20emj0qz /]# cd usr/local/nginx/sbin/ [root@izwz9cwntagbp2m20emj0qz sbin]# ./nginx [root@izwz9cwntagbp2m20emj0qz sbin]# ps aux|grep nginx root 30537 0.0 0.0 20576 624 ? ss 16:41 0:00 nginx: master process ./nginx nobody 30538 0.0 0.0 21020 1320 ? s 16:41 0:00 nginx: worker process root 30542 0.0 0.0 112812 980 pts/0 s+ 16:41 0:00 grep --color=auto nginx
