我是Nginx和uWSGI的新手。
我已在index.py
目录更新了我的/var/www/app/
。现在,当我尝试运行http://127.0.0.1/
或cp.myhost.com
时,我收到502 Bad Gateway
错误
这是nginx的配置文件:
`
server {
# Change this if you want to serve your application on another port
listen 80;
# Replace this with your domain name
server_name cp.myhost.com;
# You can use virtual directory like '/apps/' here, but remember that
# this should match 'urls' defined in your web.py application file
location / {
include uwsgi_params;
# This should match the 'socket' entry in your uwsgi configuration
#uwsgi_pass unix:///tmp/uwsgi_vhosts.sock;
uwsgi_pass 127.0.0.1:8080;
# This is the absolute path to the folder containing your application
uwsgi_param UWSGI_CHDIR /var/www/apps;
# This is actually not necessary for our simple application,
# but you may need this in future
uwsgi_param UWSGI_PYHOME /var/www/apps;
# This is the name of your application file, minus the '.py' extension
uwsgi_param UWSGI_SCRIPT index;
}
}
`
这是我在/var/www/app/index.py
import web
import MySQLdb
import datetime
app = web.application(urls, globals())
urls = (
'/', 'index'
)
class index:
def GET(self):
db = MySQLdb.connect(host="localhost",
user="root",
passwd="",
db="cw_api")
cur = db.cursor()
try:
cur.execute("SELECT MAX(sync_id) FROM settings_sync;")
db.commit()
print cur.fetchone()[0]
except:
db.rollback()
sql = "SELECT * FROM Table1 LEFT JOIN Table2 ON.... "
srtr = "<style>table, th, td {border: 1px solid black;}</style><table><tr><th>Name</th><th>Contact</th></tr>"
try:
# Execute the SQL command
cur.execute(sql)
# Fetch all the rows in a list of lists.
results = cur.fetchall()
for row in results:
srtr = srtr + "<tr><td>" + row[0] + "</td>"
srtr = srtr + "<td>" + row[1] + "</td>"
srtr = srtr + "</td></tr>"
except:
print "Error: unable to fecth data"
db.close()
srtr = srtr + "</table>"
return srtr
if __name__ == "__main__": app.run()
application = app.wsgifunc()
我是新来的,所以请帮帮我... 我认为问题出在我的代码中,但它在我的本地计算机上运行顺利。 我无法追踪代码中的错误...
我认为错误在于此代码:
db = MySQLdb.connect(host="localhost",
user="root",
passwd="",
db="cw_api")
cur = db.cursor()
我尝试将host
值更改为127.0.0.1
,但没有任何反应。
