linux centos 8下安装nginx

linux版本：CentOS8 64位

安装命令：

安装依赖
yum -y install gcc pcre-devel zlib-devel openssl openssl-devel

 nginx下载地址：https://nginx.org/download/
下载“nginx-1.9.9.tar.gz”，移动到/home/下。 

1.解压
tar -zxvf nginx-1.9.9.tar.gz

2.进入nginx目录
cd nginx-1.9.9
3.配置
./configure --prefix=/usr/local/nginx
4.安装make
make
make install
安装如图在浏览器输入地址测试是否成功

编译错误

分析原因：

是将警告当成了错误处理，打开 nginx的安装目录/objs/Makefile，去掉CFLAGS中的-Werror，再重新make

-Wall 表示打开gcc的所有警告
-Werror，它要求gcc将所有的警告当成错误进行处理

请在make后再修改这个文件，修改后再make install

如果出现下面错误

这里提示我们struct crypt_data’没有名为‘current_salt’的成员：cd.current_salt[0] = ~salt[0]；

最好的办法是换一个版本，因为条件限制，我们就进到源码里把这行直接注释掉好了

vim src/os/unix/ngx_user.c

NGINX配置虚拟主机支持PHP

在nginx.conf的http段添加include /www/server/nginx/conf/vhost/*.conf;

在/www/server/nginx/conf/vhost/中添加文件www.1.com.conf内容如下

server{

	
	
	listen 80;
    #listen [::]:80;
    server_name 1.com www.1.com;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/www.1.com;
	
	
	#自己配置
	#include vhostpath.conf;
	
	
		location ~* \.php$ {
			#root /www/wwwroot/www.1.com;
			fastcgi_pass   127.0.0.1:9000;
			fastcgi_index  index.php;
			fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
			include        fastcgi_params;
		}	
	
   
	
}

设置开机启动

设置软连接

ln -sf /www/server/nginx/sbin/nginx /usr/bin/nginx
cp /www/init.d/nginx /etc/init.d/nginx
cp/www/init.d/nginx.service /etc/systemd/system/nginx.service
chmod +x /etc/init.d/nginx

复制nginx文件内容如下面所示

查看当前状态
systemctl start nginx .service

设置开启其他

systemctl enable nginx .service

刷新配置文件

systemctl daemon-reload

systemctl list-unit-files|grep nginx

出现nginx.service enabled 表示成功开启
