CentOS 启动 Nginx

1.下载

选择的nginx-1.23.2版本

2.解压

上传centos并解压，本次解压目录在/home/install_package/nginx-1.23.2

tar -zxvf nginx-1.23.2.tar.gz

3.安装必要环境

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

4.在/opt创建目录

mkdir /opt/nginx

5.创建目录

mkdir /opt/nginx/nginx-1.23.2
mkdir /opt/nginx/temp
mkdir /opt/nginx/lock
mkdir /opt/nginx/logs

6.配置编译

自定义配置，需要手动完成第5步

cd /home/install_package/nginx-1.23.2
./configure \
--prefix=/opt/nginx/nginx-1.23.2 \
--with-http_stub_status_module --with-http_ssl_module \
--conf-path=/opt/nginx/nginx-1.23.2/conf/nginx.conf \
--pid-path=/opt/nginx/nginx-1.23.2/conf/nginx.pid \
--lock-path=/opt/nginx/lock/nginx.lock \
--error-log-path=/opt/nginx/logs/error.log \
--http-log-path=/opt/nginx/logs/access.log \
--with-http_gzip_static_module \
--http-client-body-temp-path=/opt/nginx/temp/client \
--http-proxy-temp-path=/opt/nginx/temp/proxy \
--http-fastcgi-temp-path=/opt/nginx/temp/fastcgi \
--http-uwsgi-temp-path=/opt/nginx/temp/uwsgi \
--http-scgi-temp-path=/opt/nginx/temp/scgi

7.编译并安装

cd /home/install_package/nginx-1.23.2
make && make install

8.创建ssl目录

进入/opt/nginx/nginx-1.23.2目录，创建ssl证书目录：mkdir cert

9.编辑配置文件

编辑confg/nginx.conf：

server {
	listen				443 ssl;
	server_name			www.xxx.com;
	ssl on;
	ssl_certificate			cert/server.pem;
	ssl_certificate_key		cert/server.key;
	ssl_session_timeout		5m;
	ssl_protocols			TLSv1 TLSv1.1 TLSv1.2;
	ssl_ciphers			ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
	ssl_prefer_server_ciphers	on;

	#charset koi8-r;
	#access_log logs/host.access.log  main;
	
	location / {
		tcp_nodelay		on;
		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://127.0.0.1:8080;
	}
}

server {
	listen				443 ssl;
	server_name 			app.xxx.com;
	ssl_certificate			cert/server-app.pem;
	ssl_certificate_key		cert/server-app.key;
	ssl_session_timeout		5m;
	ssl_protocols			TLSv1 TLSv1.1 TLSv1.2;
	ssl_ciphers			ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
	ssl_prefer_server_ciphers	on;

	#charset koi8-r;

	#access_log  logs/host.access.log  main;

	location / {
		tcp_nodelay		on;
		proxy_set_header	Host			$host;
		proxy_set_header	X-Real_IP		$remote_addr;
		proxy_set_header	X-Forwarded-For		$proxy_add_x_forwarded_for;
		# 以上三行目的是将代理服务器收到的用户信息传到真是服务器上
		proxy_pass		http://xxx:ooo;
	}
}

10.手动启动

cd /opt/nginx/nginx-1.23.2/sbin
./nginx -c /usr/local/nginx/conf/nginx.conf

11.手动停止

此方式停止步骤是待nginx进程处理任务完毕进行停止。

./nginx -s stop

12.手动退出

此方式相当于先查出nginx进程id再使用kill命令强制杀掉进程。

./nginx -s quit

13.手动重新加载配置

./nginx -s reload

14.常见问题处理

启动时报80端口被占用:nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

解决办法：安装net-tool 包：

yum install net-tools

15.手动重启

推荐使用quit

./nginx -s quit
./nginx

16.开机自启动

1.进入init.d目录

cd /etc/init.d

2.创建服务文件

vim nginx

3.编写脚本

#!/bin/bash
#chkconfig: 2345 63 37
#description: nginx service
#processname: nginx-1.23.2
export NGINX_HOME=/opt/nginx/nginx1.23.2
case $1 in
			start)
					$NGINX_HOME/sbin/nginx
					echo "nginx is started"
					;;
			stop)
					$NGINX_HOME/sbin/nginx -s quit
					echo "nginx is stopped"
					;;
			restart)
					$NGINX_HOME/sbin/nginx -s quit
					echo "nginx is stopped"
					sleep 1
					$NGINX_HOME/sbin/nginx
					echo "nginx is started"
					;;
			*)
			echo "start|stop|restart"
			;;
esac
exit 0

4.修改文件权限：
