想管理本部門的物品和庫房，決定采用倉庫軟件來管理，開源的好像沒有看到比較簡單的，最后選擇odoo和axelor來對比，發現后者在中國比較少，不支持中文，於是放棄。（axelor docker安裝比較簡單。）
odoo是ERP軟件，兩年前安裝過，今日再次安裝，趕緊記錄下來。裝了兩次:1,昨天網上找到centos 7安裝odoo14（知乎上有兄弟專門介紹）;2,今日開始結合多篇文章，安裝odoo15.
更新系統：
yum update -y
yum install -y epel-release
安裝python39： 有點困難的地方。
sudo yum install gcc gcc-c++ openssl-devel bzip2-devel libffi-devel libxml2-devel libxslt-devel libjpeg-turbo-devel openldap-devel -y
wget https://www.python.org/ftp/python/3.9.9/Python-3.9.9.tgz
yum install -y wget
tar xzf Python-3.9.9.tgz
cd Python-3.9.9
./configure --enable-optimizations
sudo make altinstall
python3.9 -V
創建用戶：
sudo useradd -m -U -r -d /opt/odoo -s /bin/bash odoo
sudo yum install git gcc wget nodejs libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel
安裝數據庫：
sudo yum install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
yum list postgresql
sudo yum install -y postgresql14-server
sudo /usr/pgsql-14/bin/postgresql-14-setup initdb
sudo systemctl enable postgresql-14
sudo systemctl start postgresql-14
sudo systemctl status postgresql-14
sudo su - postgres -c "createuser -s odoo"
sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox-0.12.5-1.centos7.x86_64.rpm
sudo yum localinstall wkhtmltox-0.12.5-1.centos7.x86_64.rpm
安裝ODOO15：
sudo su - odoo
git clone https://github.com/odoo/odoo.git --depth 1 --branch 15.0 /opt/odoo/odoo15
發現3小時沒有動靜，ctrl + c后再來就好了。
cd /opt/odoo
python3.9 -m venv odoo15-venv
source odoo15-venv/bin/activate
pip3 install -r odoo15/requirements.txt
/opt/odoo/odoo15-venv/bin/python3.9 -m pip install --upgrade pip 上一步出錯后需要更新一下pip
pip3 install -r odoo15/requirements.txt 再來會報以下錯：Error: pg_config executable not found.
轉到root然后執行：yum install postgresql postgresql-devel python-devel
deactivate && exit
sudo mkdir /opt/odoo/odoo15-custom-addons
udo chown odoo: /opt/odoo/odoo15-custom-addons
sudo mkdir /var/log/odoo15
sudo touch /var/log/odoo15/odoo.log
sudo chown -R odoo: /var/log/odoo15/
vi /etc/odoo.conf

sudo chmod 640 /etc/odoo.conf
