本文中使用nginx.tar.gz编译安装，并配置自签名ssl证书

首先访问官网下载nginx.tar.gz
https://nginx.org/en/download.html

示例

wget https://nginx.org/download/nginx-1.24.0.tar.gz

安装相关依赖

# 注意 redhat系列用openssl-dev debian系列用libssl-dev
apt-get -y install gcc pcre pcre-devel zlib zlib-devel openssl libssl-dev

解压安装

# tar -zxvf nginx-1.24.0.tar.gz
# cd nginx-1.24.0
# ./configure --prefix=/usr/local/nginx  --with-http_ssl_module --with-threads --with-http_realip_module --with-http_stub_status_module
# make && make install

nginx基本命令

# whereis nginx
# cd /usr/local/nginx/sbin/
# ./nginx 
# ./nginx -s stop
#./nginx -s quit
# ./nginx -s reload

nginx配置systemctl服务
vim /usr/lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

说明：

[Unit]:服务的说明
Description:描述服务
After:描述服务类别

[Service]服务运行参数的设置
Type=forking是后台运行的形式
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：启动、重启、停止命令全部要求使用绝对路径

[Install]服务安装的相关设置，可设置为多用户

授权并使其服务生效

# chmod -R 755 /usr/lib/systemd/system/nginx.service
# systemctl daemon-reload
# systemctl enable nginx.service

}

自签名证书生成sh脚本
执行vi ./key.sh
sh ./key.sh按提示即可生成证书

#!/bin/sh

# create self-signed server certificate:

read -p "Enter your domain [www.example.com]: " DOMAIN

echo "Create server key..."

openssl genrsa -des3 -out $DOMAIN.key 2048

echo "Create server certificate signing request..."

SUBJECT="/C=US/ST=Mars/L=iTranswarp/O=iTranswarp/OU=iTranswarp/CN=$DOMAIN"

openssl req -new -subj $SUBJECT -key $DOMAIN.key -out $DOMAIN.csr

echo "Remove password..."

mv $DOMAIN.key $DOMAIN.origin.key
openssl rsa -in $DOMAIN.origin.key -out $DOMAIN.key

echo "Sign SSL certificate..."

openssl x509 -req -days 3650 -in $DOMAIN.csr -signkey $DOMAIN.key -out $DOMAIN.crt

echo "TODO:"
echo "Copy $DOMAIN.crt to /etc/nginx/ssl/$DOMAIN.crt"
