需求
最近需要迁移Node线上服务,于是新申请了两台线上服务器;
部署服务器后,需要验证服务是否正常,办公环境与线上环境网络是隔离的,无法直接访问;但是,线上服务器可通过部署服务器访问,而办公网络是可以访问部署机的;
所以,可通过在部署机上配置代理的方式,办公环境请求部署机,然后把请求代理到线上服务的方式验证服务是否正常。
整个网络结构如下图所示:
Nginx安装
下载
下载页面: http://nginx.org/en/download.html选择版本鼠标右键拷贝链接地址

# 下载
[work@40-10-14 opt]$ wget http: //nginx .org /download/nginx-1 .18.0. tar .gz
# 解压文件
[work@40-10-14 opt]$ tar -xvf nginx-1.18.0. tar .gz

# 1. 默认安装:root权限进入解压后的目录,执行如下命令安装
[root@40-10-14 nginx-1.18.0] # ./configure && make && make install
# 2.指定目录:安装到指定的/opt/nginx目录
[work@40-10-14 opt]$ mkdir /opt/nginx
[work@40-10-14 nginx-1.18.0]$ . /configure --prefix= /opt/nginx && make && mae install
|
默认安装,非root权限会报如下错误

mkdir : cannot create directory ` /usr/local/nginx ': Permission denied
make [1]: *** [ install ] Error 1
make [1]: Leaving directory ` /opt/nginx-1 .18.0'
make : *** [ install ] Error 2
|
默认安装后,查看nginx的安装目录,可以看到安装在/usr/local/nginx目录下

|
[root@40-10-14 opt] # whereis nginx
nginx: /usr/local/nginx
|
1.建议使用指定目录方式安装。如果切换为root权限去安装,后续修改config文件也需要root权限
2.或者root安装后,修改权限为普通用户可操作也行
添加软链
添加软链,使得nginx命令全局能访问,每次运行就不用切换到安装目录中了

# 添加软链
[root@40-10-14 sbin] # ln -s /opt/nginx/sbin/nginx /usr/local/bin/
# 查看版本
[root@40-10-14 sbin] # nginx -v
nginx version: nginx /1 .18.0
|
常用命令
- 启动:nginx
- 停止:nginx -s stop
- 重启:nginx -s reload
- 帮助命令: nginx -h
强制停止:

# 关闭进程
[root@40-10-14 ~] # kill 45198
# 之前的进程已被关闭
[root@40-10-14 ~] # ps -ef | grep nginx
root 51277 50692 0 17:00 pts /0 00:00:00 grep nginx

配置代理
配置两台机器的请求转发,编辑nginx安装目录下的nginx/conf/nginx.conf文件即可

注意:修改完nginx的配置文件后,需要运行nginx -s reload才能生效
验证
由于线上服务很多都是需要登录的,所以访问时需要使用域名访问,而不能使用IP访问,因为cookie都是跟域名绑定的
解决这个问题很简单,配置本机host即可
1
2
|
# IP为Nginx服务器IP
xx.xx.xx.14 xxx.daojia.com
|
通过上述配置,在本机浏览器上请求xxx.daojia.com即可间接通过部署机上的Nginx访问到线上服务,以此在内网测试服务是否正确;待服务无异常后,把线上流量切过来即可。
