[jira] Updated: (TS-6) traffic_manager does not start
Posted by "George Paul (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-6?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
George Paul updated TS-6:
-------------------------
Attachment: TS-6_traffic_manager_patch4.diff
Last patch was prepared a little to quickly :-(
This updated patch replaces TS-6_traffic_manager_patch3.diff
patch -p0 -i TS-6_traffic_manager_patch4.diff
It addresses 2 more cases of TS_ROOT instead of ATS_ROOT.

[jira] Updated: (TS-6) traffic_manager does not start
Posted by "George Paul (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-6?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
George Paul updated TS-6:
-------------------------
Attachment: TS-6_traffic_manager_patch2.diff
This updated patch replaces TS-6_traffic_manager_patch1.diff and reflects changes incorporated by patch TS-21_stats_patch3.diff.
patch -p0 -i TS-6_traffic_manager_patch2.diff
You need to set 'proxy.config.cluster.ethernet_interface' in 'proxy/config/records.config.in' to a valid interface like 'eth0'.
You can bring up Traffic manager on linux:
sudo $PREFIX/bin/traffic_manager
Traffic Manger will come up with the Web interface disabled but you can execute the 'sudo $PREFIX/bin/traffic_shell' command and see some stats.
When this ticket gets closed a new ticket should be opened up regarding the Traffic Manager WebUI.

[jira] Commented: (TS-6) traffic_manager does not start
Posted by "Zhao Yongming (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-6?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779355#action_12779355 ]
Zhao Yongming commented on TS-6:
--------------------------------
there is /home/trafficserver dir hard coded in many place, we need to fix this, solutions:
1, create /home/trafficserver dir.
2, change to a system dir such as /tmp or /var/trafficserver
If we don't install the user trafficserver then we should not use /home/traffcserver, the /tmp is prefer for me.
any comment?

Leif Hedstrom commented on TS-6:
--------------------------------
Couple of comments:
+ $(INSTALL) -d -o nobody -g nobody $(pkglocalstatedir) $(pkglogdir) $(pkgsysconfdir) $(pkgsysconfdir)/internal
+ $(INSTALL) -d $(pkglibexecdir)
+ echo $(prefix) > /etc/traffic_server
We need to try to avoid hardcoding nobody / nobody, and use something in autoconf to specify this. There's a separate Jira ticket filed for tihs as well, TS-15. It'd be great to get something for this as well (if you want to leave this as is for this diff, and work on TS-15 next, that's fine :).
Should we make this a little longer than 512? Maybe 1024 ?
+#define PATH_NAME_MAX 511 // instead of PATH_MAX which is inconsistent
+ // on various OSs (linux-4096,osx/bsd-1024,
That, or I'd say we should stick to PATH_MAX, and use the limitations as per each OS (which is fine IMO). That would be my preference I think, and the more I think about it, the more it makes sense to stick to the system defaults. This happens in several places in the diff.
For this:
+ if ((env_path = getenv("ATS_ROOT")) || (env_path = getenv("ATS_INST_ROOT"))) {
+ ink_strncpy(ts_path, env_path, PATH_NAME_MAX);
I think ATS_ROOT is adequate. The old "INST_ROOT" was added to deal with an internal "anomaly" (this occurs in several places). We should also document this usage of $TS_ROOT somewhere, and make sure we use it consistently throughout the code. I think though, that I'd prefer TS_ROOT instead of ATS_, but if you want to discuss that on the -dev@ mailing list, that's cool too.
This stuff:
+ if ((fp = fopen("/etc/traffic_server", "r")) != NULL) {
+ if (fgets(ts_path, PATH_NAME_MAX, fp) == NULL) {
+ fclose(fp);
+ Cli_Error("\nInvalid contents in /etc/traffic_server\n");
+ Cli_Error(" Please set correct path in either env variable ATS_ROOT or in /etc/traffic_server \n");
+ return -1;
+ }
Shouldn't /etc/traffic_server "default" to whatever --prefix was specified? So, in the default, it would be /usr/local/etc/trafficserver (note that it's not traffic_server either). I think we should change every reference to /etc/traffic_server (or /etc/trafficserver) to be $prefix/etc/trafficserver, this happens in many places in the code.

George Paul commented on TS-6:
------------------------------
Response to comments:
1. user/group : nobody/nobody
Since there is a Jira Ticket TS-15 to cover this specific issue I would suggest that this issue gets fixed under that ticket :-)
2. PATH_NAME_MAX vs PATH_MAX
Originally PATH_NAME_MAX was to be used for PATH_MAX for portability between OS's AFAIR. TS is more consistent in the use of PATH_NAME_MAX in the code base (cache, hostdb, plugins, etc) while TM is not as consistent. TC never used it. For TM I decided to pull the TS usage of PATH_NAME_MAX and make TM more consistent with this patch. For the default value I went with what is currently set for TS. We can bump it up to 1024. If the idea is to change to using PATH_MAX everywhere we should file a separate ticket and and also look at TC. TS usage would also have to be carefully examined.
3. ATS_ROOT vs TS_ROOT
TS_ROOT is fine by me
4. /etc/traffic_server
The idea was that first entry in '/etc/traffic_server' would point the to base/root install of the version of TS that was designated to be run. You could have more than one entry in
'/etc/traffic_server' so that you could switch/rollback to a previous version(s) if you wanted/needed to by making it the first entry in the file. If a different behavior is desired I would suggest that a new ticket should be filed so that it can be addressed more consistently across all the TS applications.

[jira] Updated: (TS-6) traffic_manager does not start
Posted by "George Paul (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-6?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
George Paul updated TS-6:
-------------------------
Attachment: TS-6_traffic_manager_patch1.diff
This patch uses PREFIX,PKGLOCALSTATEDIR and PKGSYSCONFDIR to set default locations for config files, logs and IPC. It also adds a few more records config variables to set paths. This patch was used in conjuction with patches TS-36_patch1.diff and TS-21_stats_patch1.diff
patch -p0 -i TS-6_traffic_manager_patch1.diff
If you traffic_manger does not start and you see message like the following in /var/log/syslog:
Nov 19 17:36:12 wopr traffic_manager[25918]: {2243651312} NOTE: [LocalManager::initCCom] Unable to find network interface (null). Exiting...
You need to set 'proxy.config.cluster.ethernet_interface' in 'proxy/config/records.config.in' to a valid interface like 'eth0'
Also make sure you set 'proxy.config.admin.user_id' to valid user if 'nobody' does not exist.
You can ignore the errors about filter_to_policy and /usr/sbin/sendmail not being found for now. Traffic Manager should start and bring up Traffic Server.
You can execute the '$PREFIX/bin/traffic_shell' command and see some stats

[jira] Updated: (TS-6) traffic_manager does not start
Posted by "George Paul (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-6?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
George Paul updated TS-6:
-------------------------
Attachment: TS-6_traffic_manager_patch3.diff
This updated patch replaces TS-6_traffic_manager_patch2.diff
patch -p0 -i TS-6_traffic_manager_patch3.diff
The patch addresses the following issues:
1. user/group : nobody/nobody
- Jira Ticket TS-15 covers this issue
2. PATH_NAME_MAX vs PATH_MAX
- This issue has been pulled out into Jira Ticket TS-84
3. ATS_ROOT vs TS_ROOT
- TS_ROOT is the default
4. /etc/traffic_server
- This issue has been pulled out into Jira Ticket TS-85
As a recap you need to set 'proxy.config.cluster.ethernet_interface' in 'proxy/config/records.config.in' to a valid interface like 'eth0'.
You can bring up Traffic manager on linux:
sudo $PREFIX/bin/traffic_manager
Traffic Manger will come up with the Web interface disabled but you can execute the 'sudo $PREFIX/bin/traffic_shell' command and see some stats.
When this ticket gets closed a new ticket should be opened up regarding the Traffic Manager WebUI.
