一、安装
1、手动建下载好的安装包放到linux服务器上
下载地址：http://nginx.org/download/；源码安装选择.tar.gz结尾的安装包，如http://nginx.org/download/nginx-1.17.3.tar.gz
2、解压安装包
tar -zvxf nginx-1.17.3.tar.gz
3、创建安装文件夹
mkdir /home/nginx
4、安装编译环境
yum install -y curl gcc openssl-devel libnl3-devel net-snmp-devel
5、源码安装软件时配置环境用，根据你的配置选项和你的系统情况生成makefile文件，为make做准备
./configure --prefix=/home/nginx
6、编译
make
7、安装
make install
二、测试安装
1、跳转到nginx的安装位置
cd /home/nginx/sbin
2、查看nginx是否启动（未启动）
[root@localhost sbin]# ps -ef|grep nginx root 4100 1368 0 23:46 pts/0 00:00:00 grep --color=auto nginx
3、启动nginx
./nginx 或者 ./nginx -c /home/nginx/conf/nginx.conf
4、查看nginx是否启动（已启动，含主进程和后台进程）
[root@localhost sbin]# ps -ef|grep nginx root 4102 1 0 23:48 ? 00:00:00 nginx: master process ./nginx nobody 4103 4102 0 23:48 ? 00:00:00 nginx: worker process root 4105 1368 0 23:49 pts/0 00:00:00 grep --color=auto nginx
5、访问nginx方式查看启动
curl http://127.0.0.1/
<!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working. Further configuration is required.</p>
<p>For online documentation and support please refer to <a href="http://nginx.org/">nginx.org</a>.<br/> Commercial support is available at <a href="http://nginx.com/">nginx.com</a>.</p>
<p><em>Thank you for using nginx.</em></p> </body> </html>
三、Nginx设置成服务并开机自动启动
1、添加服务到service
2、编写nginx.service中的内容
[Unit] Description=nginx After=network.target [Service] Type=forking ExecStart=/home/nginx/sbin/nginx ExecReload=/home/nginx/sbin/nginx -s reload ExecStop=/home/nginx/sbin/nginx -s quit PrivateTmp=true [Install] WantedBy=multi-user.target
3、添加启动文件
vim /etc/init.d/nginx4、填写内容
#!/bin/bash # nginx Startup script for the Nginx HTTP Server # it is v.1.17.3 version. # chkconfig: - 85 15 # description: Nginx is a high-performance web and proxy server. # It has a lot of features, but it's not for everyone. # processname: nginx # pidfile: /var/run/nginx.pid # config: /usr/local/nginx/conf/nginx.conf nginxd=/home/nginx/sbin/nginx nginx_config=/home/nginx/conf/nginx.conf nginx_pid=/var/run/nginx.pid RETVAL=0 prog="nginx" # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ ${NETWORKING} = "no" ] && exit 0 [ -x $nginxd ] || exit 0 # Start nginx daemons functions. start() { if [ -e $nginx_pid ];then echo "nginx already running...." exit 1 fi echo -n $"Starting $prog: " daemon $nginxd -c ${nginx_config} RETVAL=$? echo [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx return $RETVAL } # Stop nginx daemons functions. stop() { echo -n $"Stopping $prog: " killproc $nginxd RETVAL=$? echo [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid } # reload nginx service functions. reload() { echo -n $"Reloading $prog: " #kill -HUP `cat ${nginx_pid}` killproc $nginxd -HUP RETVAL=$? echo } # See how we were called. case "$1" in start) start ;; stop) stop ;; reload) reload ;; restart) stop start ;; status) status $prog RETVAL=$? ;; *) echo $"Usage: $prog {start|stop|restart|reload|status|help}" exit 1 esac exit $RETVAL5、保存后设置文件的执行权限
chmod 777 /etc/init.d/nginx6、启动或停止nginx(可能无法停止，因为守护进程存在)
/etc/init.d/nginx start /etc/init.d/nginx stop7、步骤4中的方式虽能启动，但是也不太方便，添加到服务中开机自启动。
chkconfig --add /etc/init.d/nginx8、设置开机自启动
chkconfig nginx on9、查看自启动服务列表
chkconfig --list
10、通过服务方式管理nginx，相关命令：
service nginx start service nginx stop service nginx restart11、同时也可使用systemctl（管理systemd的资源Unit，即.service文件，兼容service命令）进行管理，常见命令：
# systemctl start nginx 启动服务
# systemctl stop nginx 停止服务
# systemctl restart nginx 重启服务
# systemctl status nginx 查看服务当前状态
# systemctl list-units --type=service 查看所有已启动的服务
