命令启动odoo
./odoo-bin --addons-path=addons,./myproject -d dev12 -u library_app
./myproject 自己定义的模块目录
odoo.cli.main() 程序入口
根据程序入口找到odoo/cli/command.py里面的def main()函数
def main():
args = sys.argv[1:]
# 根据输入的启动命令 args：['--addons-path=addons,./myproject', '-d', 'dev12', '-u', 'library_app']

# commands from modules
if len(args) > 1 and args[0].startswith('--addons-path=') and not args[1].startswith("-"):
# 只分析加载项路径，不设置记录器…
odoo.tools.config._parse_config([args[0]])
args = args[1:]
# args[0]:--addons-path=addons,./myproject, args[1]开头为- 所以条件不成立
# 默认的 command
command = "server"
# TODO: find a way to properly discover addons subcommands without importing the world
# Subcommand discovery
if len(args) and not args[0].startswith("-"): # 条件不成立
logging.disable(logging.CRITICAL) # 禁用等级为CRITICAL的日志
# get_modules()为返回模块名称列表
for module in get_modules():
#isdir 判断是否为目录
if isdir(joinpath(get_module_path(module), 'cli')):
__import__('odoo.addons.' + module)
# 这里的条件是不成立的
logging.disable(logging.NOTSET)
command = args[0]
args = args[1:]
# 这里commands为{'help': <class 'odoo.cli.command.Help'>, 'scaffold': <class 'odoo.cli.scaffold.Scaffold'>,

o.run(args) # 调用cli下的Server.py 文件中的Server方法下的run函数
else:
sys.exit('Unknow command %r' % (command,))
接下来继续运行run()函数
class Server(Command):
"""Start the odoo server (default command)"""
def run(self, args):
main(args)
从run()函数了解到接下来要运行main()函数
def main(args):
check_root_user() # 判断是否为POSIX系统中的root用户
# 如果是的话 则判断当前用户是否为root，因为使用系统用户root作为odoo的user是一个不安全的做法

check_postgres_user() # 检测到用户是‘postgres’会拒绝登陆，并且弹出错误信息

接着开始start()函数的运行

可以看出从程序入口文件一直到程序成功运行，需要整理好并传输程序运行所需的的配置，根据配置创建好所需要的数据库，加载好模块，运行客户端，然后通过ThreadedServer创建的线程来运行服务
