服务器安装Nginx

环境

• CentOS 8
• 使用编译安装 Nginx

Nginx使用Docker安装确实有点麻烦，需要将很多前端文件映射到容器内部，不推荐

正式环境

1、安装环境需要的依赖包

yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

2、在你的linux服务器上创建目录：nginx

cd /root && mkdir nginx

3、进入刚才安装的目录

cd nginx

4、下载并且解压安装包

wget http://nginx.org/download/nginx-1.13.7.tar.gz && tar -zxvf nginx-1.13.7.tar.gz  

5、进入刚刚解压好的目录

cd nginx-1.13.7

6、添加一些常用的模块，比如：gzip、https 模块

./configure --with-http_gzip_static_module --with-http_stub_status_module  --with-http_stub_status_module --with-http_ssl_module

7、 执行下面的命令

make && make install

make指令报错解决办法：https://blog.csdn.net/qq_45697992/article/details/120028370

8、设置 Linux 环境变量

1）编辑 /etc/profile 文件

vi /etc/profile

2）在最后一行添加下面的代码

PATH=$PATH:/usr/local/nginx/sbin
export PATH

3）让配置生效

source /etc/profile

9、任意目录下输入

nginx

10、访问服务器 IP

curl http://localhost

Nginx 常用命令

按照上面安装之后，nginx 的位置在哪里？

/usr/local/nginx/sbin

1、检查 Nginx 配置文件的语法

nginx -t

2、显示 Nginx 版本信息

nginx -v

3、查看编译时的配置参数 （大写的 V）

nginx -V

4、重启 Nginx

nginx -s stop

5、重新加载配置文件

nginx -s reload

如果出现上面的报错，就检查一下 nginx 配置文件

遇到的报错

当输入 nginx -s reload 时报错 nginx: [error] invalid PID number

解决：

sudo pkill -f nginx

强制删除 Nginx 进程，然后再重新启动

nginx
