准备

下载`nginx`源码包

在源码安装前，我们得先下载nginx源码包
https://nginx.org/download/
这里我下载的是nginx-1.23.0.tar.gz版本
下载完之后，我们使用mobaxterm将nginx-1.23.0.tar.gz上传到我们的Linux服务器的/root/目录下

[root@CentOS ~]# ls
anaconda-ks.cfg  nginx-1.23.0.tar.gz

关闭防火墙

[root@centos ~]# systemctl disable firewalld
[root@centos ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

关闭`selinux`

[root@centos ~]# vim /etc/selinux/config

安装依赖环境

[root@centos ~]# yum install gcc gcc-g++ pcre-devel openssl-devel zlib-devel make -y

解压

解压

[root@centos ~]# tar -zxvf nginx-1.23.0.tar.gz

改名

[root@centos ~]# ls
anaconda-ks.cfg  nginx-1.23.0  nginx-1.23.0.tar.gz
[root@centos ~]# mv nginx-1.23.0 nginx    #改名
[root@centos ~]# ls
anaconda-ks.cfg  nginx  nginx-1.23.0.tar.gz

[root@centos ~]# cd nginx
[root@centos nginx]# ls
auto  CHANGES  CHANGES.ru  conf  configure  contrib  html  LICENSE  man  README  src

编译

[root@centos nginx]# ./configure

安装

[root@centos nginx]# make && make install

默认安装路径在/usr/local/nginx中
切换到/usr/local/nginx中

[root@centos nginx]# pwd
/root/nginx
[root@centos nginx]# cd /usr/local/nginx/
[root@centos nginx]# pwd
/usr/local/nginx
[root@centos nginx]# ls
conf  html  logs  sbin

测试

[root@centos nginx]# ls
conf  html  logs  sbin
[root@centos nginx]# cd sbin
[root@centos sbin]# ls
nginx
[root@centos sbin]# ./nginx     #启动服务

编写服务脚本，通过`systemctl`实现服务启动与关闭

在Linux系统中，systemd是初始化系统和服务管理器的标准，用于管理系统的启动和运行。systemd的配置文件通常位于/etc/systemd/system/或/usr/lib/systemd/system/目录下，这些文件以.service结尾，定义了服务的启动、运行、停止等行为。
systemd是CentOS系统操作系统开始启用新的系统和服务管理器

在这里插入图片描述

[root@centos ~]# vim /usr/lib/systemd/system/nginx.service
[Unit]
Description=ngixn server
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx

[Install]
WantedBy=multi-user.target

重新加载

[root@centos ~]# systemctl daemon-reload

测试

[root@centos ~]# systemctl start nginx
[root@centos ~]# systemctl status nginx
