Last active August 29, 2015 13:58
Key config to make cgit work under nginx
# The .css and image files required by CGit should be copied to /var/www/cgit-css
# as nginx concat the matched URI with the document root which is very different
# from Apache's Alias directive.
location /cgit-css {
root /var/www;
index index.html index.htm;
}
# The cgit.cgi program does not work if the whole URI is passed as PATH_INFO.
# Strip the CGI program name from URI and set PATH_INFO to the remaining part,

d -- no affinity
);
-- Values will be stored as TEXT, INTEGER, TEXT, and INTEGER respectively
INSERT INTO t1 VALUES('500', '500', '500', 500);
