1、配置 Nginx，配置 ssl 证书
#

我的 Web Server 用的 Nginx，Gateone 也用到了 Nginx 的代理功能，所以选择了 Nginx。可以自己编译安装，也可以用 oneinstack，LNMP 一键包等；证书用的是 Let’s Encrypt。

2、安装 Gateone
#

方法一：源码安装
(1)、下载源码：

wget -c https://github.com/downloads/liftoff/GateOne/gateone-1.1.tar.gz
tar -vxf gateone-1.1.tar.gz
cd GateOne

(2)、配置 Gateone 依赖环境

sudo apt-get install python-pip
sudo apt-get install python-imaging
sudo pip install pyopen    ssl
sudo pip install ordereddict
sudo pip install tornado==2.4.1 #2.4.1

(3)、开始安装，请确认是在 gateone dir 中

sudo python setup.py install

方法二：安装 deb 包

wget -c https://github.com/downloads/liftoff/GateOne/gateone_1.1-1_all.deb
sudo dpkg -i gateone*.deb

3、修改配置文件
#

先生成一个默认的配置文件

cd /opt/gateone
./gateone.py

然后修改配置文件

sudo vim /opt/gateone/server.conf

#-*- coding: utf-8 -*-
locale = "zh_CN"
pam_service = "login"
syslog_facility = "daemon"
syslog_host = None
enable_unix_socket = False
port = 22222 #商品号，随意写，但要记住
uid = "0"
url_prefix = "/"
user_dir = "/opt/gateone/users"
dtach = True
certificate = "/etc/letsencrypt/live/su-root.top/fullchain.pem" #    ssl 证书
log_to_stderr = False
session_logs_max_age = "30d"
gid = "0"
pid_file = "/var/run/gateone.pid"
sso_realm = None
cookie_secret = "70NP1WQKUSD3ZJ84AF2ERMXGIOCLBYHV9T56"
pam_realm = "yours"
sso_service = "HTTP"
https_redirect = False
syslog_session_logging = False
disable_    ssl = False
debug = False
session_dir = "/tmp/gateone"
auth = "none"
address = "127.0.0.1"
api_timestamp_window = "30s"
log_file_num_backups = 10
logging = "info"
embedded = False
origins = "https://127.0.0.1;https://su-root.top;" #重要！请填入需要用到的 ip 和域名
session_logging = True
unix_socket_path = "/var/run/gateone.sock"
    ssl_auth = "none"
log_file_max_size = 104857600
session_timeout = "5d"
command = "/opt/gateone/plugins/ssh/scripts/ssh_connect.py -S '/tmp/gateone/% SESSION%/% SHORT_SOCKET%' --sshfp -a '-oUserKnownHostsFile=% USERDIR%/% USER%/ssh/known_hosts'"
ca_certs = None
js_init = ""
keyfile = "/etc/letsencrypt/live/su-root.top/privkey.pem" #    ssl 密钥
log_file_prefix = "/opt/gateone/logs/webserver.log"

:wq 保存后，重新测试一下

cd /opt/gateone
./gateone.py

在浏览器中打开 https://ip:22222 即可使用。

4、配置 Nginx 代理端口
#

如果使用 https://gateone.com:22222 这样的地址，不方便不美观也不容易记，如果用 Nginx 代理端口，就能使用 https://gateone.com 来使用了 Gateone 了。

sudo vim your/nginx/dir*******/su-root.top.conf

修改为：

强制跳转到 https
#

server {
    listen 80;
    server_name su-root.top www.su-root.top;
    rewrite ^(.*)$ https://$host$1 permanent;
} 
server {
    listen 443     ssl http2;
    ssl_certificate /usr/local/nginx/conf/    ssl/su-root.top.crt;
    ssl_certificate_key /usr/local/nginx/conf/    ssl/su-root.top.key;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
    ssl_prefer_server_ciphers on;
    ssl_session_timeout 10m;
    ssl_session_cache builtin:1000 shared:    ssl:10m;
    ssl_buffer_size 1400;
    add_header Strict-Transport-Security max-age=15768000;
    ssl_stapling on;
    ssl_stapling_verify on;
    server_name su-root.top www.su-root.top;

# 代理端口
    location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_pass https://127.0.0.1:22222; #跟 gateone 设置的端口号匹配
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
