、安装编译所需要的库和编译器

apt-get install build-essential

二、下载编译Nginx所需要的库

zlib
openssl
pcre
nginx

解压每个压缩文件

$ tar zxvf zlib-1.2.11.tar.gz
$ tar zxvf pcre-8.43.tar.gz
$ tar zxvf openssl-1.1.1g.tar.gz
$ tar zxvf nginx-1.18.0.tar.gz

三、编译nginx

$ cd /opt/nginx-1.18.0
$ ./configure 					\
--prefix=/usr/local/nginx \
--with-http_realip_module \
--with-http_addition_module\ 
--with-http_gzip_static_module \
--with-http_secure_link_module \
--with-http_stub_status_module \
--with-stream \
--with-pcre=/opt/pcre-8.43 \
--with-zlib=/opt/zlib-1.2.11 \ 
--with-openssl=/opt/openssl-1.1.1g
$  ./configure --prefix=/usr/local/nginx --with-http_realip_module --with-http_addition_module --with-http_gzip_static_module --with-http_secure_link_module --with-http_stub_status_module --with-stream --with-http_ssl_module --with-pcre=../pcre-8.43 --with-zlib=../zlib-1.2.11 --with-openssl=../openssl-1.1.1g
$ make -j4
$ make install

四、检查是否安装成功

cd /usr/local/nginx/sbin
# 检查配置文件
nginx -t
# 启动nginx
./nginx
# 在浏览器上输入nginx的服务器IP，既可进入nginx页面

五、创建配置文件夹（可选）

创建配置文件子目录和在nginx.conf中包含conf.d

sudo mkdir /usr/local/nginx/conf/conf.d

修改/usr/local/nginx/conf/nginx.conf

sudo vim /usr/local/nginx/conf/nginx.conf

末尾{之前添加

include /usr/local/nginx/conf/conf.d/*.conf;

六、创建service

创建service文件

vim /lib/systemd/system/nginx.service

内容如下：

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

[Service]
Type=forking
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
[Install]
WantedBy=multi-user.target

给nginx.service加可执行权限

chmod +x /lib/systemd/system/nginx.service

重新加载systemctl
```
systemctl daemon-reload
```
常用命令
- 启动：sudo systemctl start nginx.service
- 停止：sudo systemctl stop nginx.service
- 重新加载：sudo systemctl reload nginx.service
- 显示nginx服务的状态：systemctl status nginx.service
- 在开机时启用nginx服务：sudo systemctl enable nginx.service
- 在开机时禁用nginx服务：sudo systemctl disable nginx.service
