例如我的安装目录是/usr/local/nginx 修改配置后重新加载生效 /usr/local/nginx/sbin/nginx -s reload 重新打开日志文件 /usr/local/nginx/sbin/nginx -s reopen 测试nginx配置文件是否正确 /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf 启动nginx /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf 快速停止nginx /usr/local/nginx/sbin/nginx -s stop 完整有序的停止nginx /usr/local/nginx/sbin/nginx -s quit 注:stop和quit的区别在于 quit是一个优雅的关闭方式,Nginx在退出前完成已经接受的连接请求 Stop 是快速关闭,不管有没有正在处理的请求。 其他的停止nginx 方式: ps -ef | grep nginx kill -QUIT 主进程号 :从容停止Nginx kill -TERM 主进程号 :快速停止Nginx pkill -9 nginx :强制停止Nginx 平滑重启nginx: kill -HUP 主进程号 为了方便,现将nginx服务添加至systemctl 1.修改nginx配置文件,开启pid pid /var/run/nginx.pid; 2.通过上述方式关闭nginx服务 3.配置服务,在/usr/lib/systemd/system/nginx.service文件,vim编辑如下 vi /usr/lib/systemd/system/nginx.service [Unit] Description=nginx - high performance web server After=network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/var/run/nginx.pid ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf ExecReload=/usr/local/nginx/sbin/nginx -s reload ExecStop=/usr/local/nginx/sbin/nginx -s stop ExecQuit=/usr/local/nginx/sbin/nginx -s quit PrivateTmp=true [Install] WantedBy=multi-user.target [Unit]部分主要是对这个服务的说明,内容包括Description和After,Description用于描述服务,After用于描述服务类别 [Service]部分是服务的关键,是服务的一些具体运行参数的设置,这里Type=forking是后台运行的形式,PIDFile为存放PID的文件路径,ExecStart为服务的具体运行命令,ExecReload为重启命令,ExecStop为停止命令,PrivateTmp=True表示给服务分配独立的临时空间,注意:[Service]部分的启动、重启、停止命令全部要求使用绝对路径,使用相对路径则会报错! [Install]部分是服务安装的相关设置,可设置为多用户的 服务脚本按照上面编写完成后,以754的权限保存在/usr/lib/systemd/system目录下 然后执行(修改或新增文件需要执行以下语句才能生效) systemctl daemon-reload 这时就可以利用systemctl进行配置了 systemctl start/stop/reload/quit nginx.service 若发生报错,可通过systemctl status nginx.service查看失败原因 systemctl enable nginx.service 开机自启动
upstream
upstream read.zhaitua.com { server 172.18.140.166:1080 weight=5; # server 172.18.140.165:1080 weight=1; keepalive 32; }
troubleshooting
原因: 502 GAT away Php-cgi进程挂掉或者是没有cgi进程
504 timeout Nginx请求不到php-cgi进程,超时
解决方法: 思路:
502错误和php-fpm.conf配置文件有关系,网上很多教程都说了,一般就设置以下几个选项

yum install
RHEL/CentOS Install the prerequisites: sudo yum install yum-utils To set up the yum repository, create the file named /etc/yum.repos.d/nginx.repo with the following contents: [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true [nginx-mainline] name=nginx mainline repo baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/ gpgcheck=1 enabled=0 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true By default, the repository for stable nginx packages is used. If you would like to use mainline nginx packages, run the following command: sudo yum-config-manager --enable nginx-mainline To install nginx, run the following command: sudo yum install nginx #issue GPG key retrieval failed: [Errno 14] curl#60 - “Peer‘s Certificate issuer is not recognized.“ wget https://nginx.org/keys/nginx_signing.key --no-check-certificate rpm --import nginx_signing.key yum install nginx
