Follow the below steps to install Odoo 14 on Ubuntu 20.04 LTS

注意：

1、建立系統使用者 odoo，檔案sudo nano /etc/systemd/system/odoo.service 中需要設定 ；

2、建立 postgresql 使用者 odoo_14和密碼 odoo14, 檔案sudo nano /etc/systemd/system/odoo.service中需要設定使用者和密碼；

3、檔案 sudo nano /etc/postgresql/12/main/pg_hba.conf 中需要增加使用者；

Step-1: Keep update your Server

sudo apt-get update
sudo apt-get upgrade

Step 2: Secure your system

sudo apt-get install openssh-server fail2ban

Step 3: Create a system user

sudo adduser --system --home=/opt/odoo --group odoo

Step 4: Installing Packages and libraries

Install pip3:

sudo apt-get install -y python3-pip

Install Packages and libraries:

sudo apt-get install python-dev python3-dev libxml2-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-dev build-essential libssl-dev libffi-dev libmysqlclient-dev libjpeg-dev libpq-dev libjpeg8-dev liblcms2-dev libblas-dev libatlas-base-dev

Ensure that all packages are successfully installed. Moreover, there are some web dependencies that also need to be installed.

sudo apt --fix-broken install
sudo apt-get install -y npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
sudo npm install -g less less-plugin-clean-css
sudo apt-get install -y node-less

Step: 5: Configure Postgresql

sudo apt-get install postgresql
sudo su - postgres
createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo_14
psql
ALTER USER odoo_14 WITH SUPERUSER;
\q
exit

在postgres配置檔案中增加建立的odoo_14使用者：

sudo nano /etc/postgresql/12/main/pg_hba.conf
 
local   all             postgres                                peer
local   all             odoo_14                                 md5

Step 6: Get Odoo community from git

sudo apt-get install git

Now before cloning, we have to change the system user as odoo (which is created in Step 3) to make the Odoo system more secure.

sudo su - odoo -s /bin/bash
git clone https://gitee.com/mirrors/odoo  --depth 1 --branch 14.0  --single-branch .
exit

Source files are cloned to the home directory of user odoo. Moreover, the home directory of the user is specified at the time of user creation. Which is /opt/odoo.
Now exit and continue with the installation.

Step 7: Install required python packages 或換成gitee中的包

sudo pip3 install -r /opt/odoo/requirements.txt
sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb
sudo apt install -f
sudo dpkg -i wkhtmltox_0.12.5-1.bionic_amd64.deb

或換成gitee中的包

sudo wget https://gitee.com/wkhtmltopdf/wkhtmltopdf/attach_files/662857/download/wkhtmltox_0.12.5-1.bionic_amd64.deb

Step 8: Configuration of Odoo,db_user和db_password需修改為上面第5步建立的。

sudo cp /opt/odoo/debian/odoo.conf /etc/odoo.conf
sudo nano /etc/odoo.conf

[options]
   ; This is the password that allows database operations:
   admin_passwd = admin
   db_host = False
   db_port = False
   db_user = odoo_14
   db_password = odoo14
   addons_path = /opt/odoo/addons
   logfile = /var/log/odoo/odoo.log

sudo chown odoo: /etc/odoo.conf
sudo chmod 640 /etc/odoo.conf

sudo mkdir /var/log/odoo
sudo chown odoo:root /var/log/odoo

Step 9: Create new service for odoo

sudo nano /etc/systemd/system/odoo.service

[Unit]
   Description=Odoo
   Documentation=http://www.odoo.com
   [Service]
   # Ubuntu/Debian convention:
   Type=simple
   User=odoo
   ExecStart=/opt/odoo/odoo-bin -c /etc/odoo.conf
   [Install]
   WantedBy=default.target

sudo chmod 755 /etc/systemd/system/odoo.service
sudo chown root: /etc/systemd/system/odoo.service

Step 10: Run Odoo 14

sudo systemctl start odoo.service
sudo systemctl status odoo.service
sudo systemctl restart odoo.service
sudo systemctl daemon-reload

“http://<your_domain_or_IP_address>:8069”

sudo tail -f /var/log/odoo/odoo.log

If you need Odoo service to start automatically on boot time, you can use the following command.

sudo systemctl enable odoo.service

Step 11: 重啟伺服器

ubuntu@VM-0-11-ubuntu:~$ sudo reboot

---------------完成---------------------

Setp 11：安裝寶塔進行管理檔案及設定Nginx代理。

sudo apt-get install nginx
nginx -v
cd /etc/nginx/conf.d
sudo touch odoo_skydba.conf
sudo vi odoo_skydba.conf

upstream odoo {
        server 127.0.0.1:8069;
}
server {
        listen 80;
        server_name www.skydba.com;
        location / {
        # 後端的Web伺服器可以通過X-Forwarded-For獲取使用者真實IP
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X_Nginx_Proxy true;
        proxy_pass http://odoo;
        proxy_redirect off;
        }
}
server{
    listen 80;
    server_name odoo.lecc.cn; #繫結域名
    index index.htm index.html index.php; #預設檔案
    root /home/www/msn.itblood.com; #網站根目錄
    include location.conf; #呼叫其他規則，也可去除
}

sudo vi /etc/nginx/conf.d/odoo_skydba.conf

ssl證書上傳到/etc/nginx

upstream odoo {
        server 127.0.0.1:8069;
}
server {
        listen 443 ssl;
         server_name www.skydba.com;
         #證書檔名稱
         ssl_certificate 1_www.skydba.com_bundle.crt;
         #私鑰檔名稱
         ssl_certificate_key 2_www.skydba.com.key;
         ssl_session_timeout 5m;
         #請按照以下協議配置
         ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
         #請按照以下套件配置，配置加密套件，寫法遵循 openssl 標準。
         ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
         ssl_prefer_server_ciphers on;
        location / {
        # 後端的Web伺服器可以通過X-Forwarded-For獲取使用者真實IP
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X_Nginx_Proxy true;
        proxy_pass http://odoo;
        proxy_redirect off;
        }
}

啟動Nginx並設定開機自動執行

sudo systemctl start nginx.service
sudo systemctl enable nginx.service
sudo systemctl stop nginx.service
systemctl status nginx

nginx -s reload  ：修改配置後重新載入生效
nginx -s reopen  ：重新開啟日誌檔案
nginx -t -c /path/to/nginx.conf 測試nginx配置檔案是否正確

關閉nginx：
nginx -s stop :快速停止nginx
quit ：完整有序的停止nginx
其他的停止nginx 方式：
ps -ef | grep nginx
kill -QUIT 主程序號 ：從容停止Nginx
kill -TERM 主程序號 ：快速停止Nginx
pkill -9 nginx ：強制停止Nginx
啟動nginx:
nginx -c /path/to/nginx.conf
平滑重啟nginx：
kill -HUP 主程序

上傳檔案大小限制修改 在配置檔案http中加入下面配置

client_max_body_size 50M;

ubuntu@VM-0-11-ubuntu:~$ sudo vi /etc/nginx/nginx.conf

ubuntu@VM-0-11-ubuntu:~$ sudo nginx -s reload

ubuntu@VM-0-11-ubuntu:~$ sudo systemctl stop nginx.service

ubuntu@VM-0-11-ubuntu:~$ sudo systemctl start nginx.service

---------------Nginx 完成---------------------
