Linux下nginx安装步骤

一、下载安装包

https://nginx.org/en/download.html

二、发送到虚拟机并解压

解压命令

tar -zxvf nginx-1.22.0.tar.gz

三、下载依赖

进入到解压文件根目录，执行命令行，检查安装环境

./configure  --prefix=/usr/local/nginx

---

安装gcc库

yum install -y gcc

---

安装pcre库

yum install -y pcre pcre-dev

centos8 yum -y install pcre-devel

安装zlib库

yum install -y zlib zlib-dev

centos8 yum install-y zlib-devel

再执行./configure --prefix=/usr/local/nginx如下所示即OK

四、编译

make

五、安装

make install

六、启动nginx

进入安装好的目录/usr/local/nginx/sbin

./nginx  启动
./nginx -s stop  快速停止
./nginx -s quit 优雅关闭，在退出前完成已经接受的连接请求
./nginx -s reload 重新加载配置

查看虚拟机IP地址ip addr,打开浏览器访问ip

若不能访问，请关掉防火墙

七、防火墙

关闭防火墙

systemctl stop firewalld.service

禁止防火墙开机启动

systemctl disable firewalld.service

放行端口

firewall-cmd --zone=public --add-port=80/tcp --permanent

重启防火墙

firewall-cmd --reload

八、开启系统服务

创建服务脚本

vim /usr/lib/systemd/system/nginx.service

服务内容

[Unit]
Description=nginx -web server
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/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

重新加载系统服务

systemctl daemon-reload

查看nginx是否在运行

ps -ef | grep nginx

关闭

./nginx -s stop

启动服务

systemctl start nginx.service

九、开机启动

systemctl enable nginx.servive
