odoo12因为yum依赖的问题，不能直接使用rpm包安装，所以我们这里补充一下源码的部署安装过程.这里演示odoo12在centos7的安装过程版.
准备一个虚拟机或云服务器
腾讯云服务器可以使用此链接购买
配置centos源
因为centos7.6不自带python3
sudo yum -y update
sudo yum install epel-release centos-release-scl -y
sudo yum install rh-python36 git gcc wget libxslt-devel bzip2-devel openldap-devel libjpeg-devel freetype-devel -y
如何此条命令没有安装上python3，可以使用本站的centos7下yum安装python3完整版搭建方法搭建
添加odoo用户
sudo useradd -m -U -r -d /opt/odoo -s /bin/bash odoo
安装postgresql
创建odoo用户,配置服务器自启动postgresql
sudo yum install https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm
sudo yum install postgresql10-server postgresql10-devel
sudo /usr/pgsql-10/bin/postgresql-10-setup initdb
sudo systemctl enable postgresql-10
sudo systemctl start postgresql-10
sudo su - postgres -c "createuser -s odoo"
yum install postgresql-devel*
yum install python3-devel
yum install openldap-devel
安装odoo打印相关的包
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox-0.12.5-1.centos7.x86_64.rpm
yum localinstall wkhtmltox-0.12.5-1.centos7.x86_64.rpm -y
yum install wqy-microhei-fonts wqy-zenhei-fonts -y
切换用户,下载安装odoo12
由于国外地址比较慢，推荐中国地址下载.本文采用中国地址
sudo su - odoo
cd ~
git clone https://gitee.com/mirrors/odoo.git --depth 1 --branch 12.0 --single-branch odoo12ce
进入python3环境,编译安装odoo12
scl enable rh-python36 bash
cd odoo12ce
python3 -m venv venv
source venv/bin/activate
pip3 install -r requirements.txt
创建目录，编辑odoo12配置文件
mkdir /opt/odoo/odoo12ce/myaddons
mkdir /opt/odoo/odoo12ce/data
vim /opt/odoo/odoo12ce/odoo.conf
[options]

db_user = odoo
db_password = False
data_dir = /opt/odoo/odoo12ce/data
addons_path = /opt/odoo/odoo12ce/odoo/addons,/opt/odoo/odoo12ce/addons, /opt/odoo/odoo12ce/myaddons
设置odoo12为服务启动
