cannot render latex on a locally run server #2

Closed walkerlala closed 7 years ago

walkerlala commented 7 years ago

Hi, I try to run the *tex.s2cms.ru server locally but got some problems.

I successfully bring up nginx server and I can see the index page at http://my.host.latex.net. (my.host.latex.net is my local host). But when I try to render the latex image using http://my.host.latex.net/svg/f(x)%20%3D%20x%20y, I got 502 Bad Gateway, and in the log file, I see something like fail to connect to php5-fpm-tex..... Then I check for /var/run/php5-fpm-tex and find only /var/run/php5-fpm-tex. How can I bring up this php5-fpm-tex? May be I miss configure something?

Actually when I configure this server I got something weird.

First of all when I try grunt it complain about 

Running "shell:gzip_page" (shell) task
Warning: An error occurred while processing a template (Cannot read property 'dest' of undefined). Use --force to continue.

Clearly there is something miss in the shell:gzip entry in the gruntfile.js file. How can I fix this ?

I haven't set anything proc_open(), but I have ensured that in my php.ini , proc_open is not in the disable line.

The requirement say that I have to install Nginx with ngx_http_lua_module, so I use apt-get install nginx-extras in Ubuntu. Is this OK ?

Thanks!

parpalak commented 7 years ago

/var/run/php5-fpm-tex is a socket from my php-fpm config. You have to set up a virtual host in nginx with php-fpm. You can follow any instruction to do that.

I've removed unused "shell:gzip_page" task. Thanks for reporting.

proc_open() is a standard PHP function. Do you need help for it?

I use nginx-extras in Debian. I think the package in Ubuntu has the same functions.

walkerlala commented 7 years ago

So you mean that I have to setup both /var/run/php5-fpm-tex.sock and /var/run/php5-fpm.sock ? Can I setup only /var/run/php5-fmp.sock and use this for php-sock and php-tex-sock ?

proc_open() is OK in my machine now.

One more: the svg directory is still missing. When I use a browser to request something like http://my.host.latex.net/svg/f(x)%20%3D%20x%20y I see a net::ERR_CONNECTION_REFUSED error. Can you tell me how to fix this ?

parpalak commented 7 years ago

You can use only one socket /var/run/php5-fmp.sock in both locations. I've set up different sockets for several php-fpm pools because of security and performance. It's irrelevant for your case.

svg is not a name of a (real) directory. URLs /svg/... are processed with nginx and PHP. This error will disappear when you set up PHP.

Thanks, but I still cannot correctly render out latex image. Whenever I request a latex image (for example, http://my.latex.host.net/svg/%20%5Chat%7By_j%7D%20) I get a 200 response, but that is an empty response (my browser say This XML file does not appear to have any style information associated with it. The document tree is shown below.).

The log are list below:

the php5-fpm log:

- -  01/Jan/1970:08:00:00 +0800 "GET /render.php" 200 /var/www/html/tex.s2cms.ru/www/render.php 715081.150 512 0.03%

the nginx error.log:

2016/12/18 12:30:14 [error] 1415#0: *9 FastCGI sent in stderr: "PHP message: PHP Warning:  file_get_contents(/home/walkerlala/software/tex.s2cms.ru/www/tmp/ms76lH.svg): failed to open stream: No such file or directory in /home/walkerlala/software/tex.s2cms.ru/lib/Renderer.php on line 198" while reading response header from upstream, client: 127.0.0.1, server: oh.my.latex.net, request: "GET /svg/%20%5Chat%7By_j%7D%20 HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "my.latex.host.net"

the nginx access.log:

the tex_logs/log-----.txt is empty

FIles in directories _cache and _error are empty.

the /var/log/php5-fpm.log is empty.

For your information, /var/www/html/tex.s2cms.ru/www is the document root and /var/www/html/tex.s2cms.ru is simlinked to /home/walkerlala/softwares/tex.s2cms.ru, where the source exists.

Any hint?

walkerlala commented 7 years ago

p.s., when I put define('TEX_PATH', '/usr/bin'); in config.php, the tex path is generated as '/usr/bintex' and that crash. Changing it to define('TEX_PATH', '/usr/bin/'); makes it work correctly.

parpalak commented 7 years ago

Seems like dvisvgm is not installed on your system. To check this, try to run dvisvgm file.dvi -o file.svg on a separate dvi-file generated by latex.

Also you can enable the debug mode by adding define('DEBUG', 1); to config.php. You'll see the additional debug info directly in browser.

walkerlala commented 7 years ago

dvisvgm has been installed correctly.

This is the debug message when I request http://my.latex.host.net/svg/%20gradients%20:

You can try to comment (or remove) $this->cleanupTempFiles($tmpName); at the following line.

After that examine the /home/walkerlala/software/tex.s2cms.ru/www/tmp/ dir and try to convert files "by hand". In particular, check the command

/usr/bin/dvisvgm <file>.dvi -o <file>.svg -n --exact --relative --zoom=1.2546875

without -v0 option for error messages.

In log/error.log, I get:

There is a /home/walkerlala/software/tex.s2cms.ru/www/tmp/8BeVgT.svg on my machine, but it has no 8BeVgT.svg, only 8BeVgT.dvi.

What am I missing ?

parpalak commented 7 years ago

Well, try to run dvisvgm for 8BeVgT.dvi as I wrote above. There must be a error message.

walkerlala commented 7 years ago

No there is no error message. It just output:

parpalak commented 7 years ago

Maybe that's the reason. These options are described in the dvisvgm documentation. You could replace the options in the dvisvg command or install a fresh version of dvisvgm or TeX Live.

walkerlala commented 7 years ago

Yes, you are right. On my ubuntu 14.04, dvisvgm is provided by package texlive-binaries and is a pretty old version(1.02). I compile the newest version(2.04) myself and it work correctly. Thanks.
