This guide is for Fedora core 20 only.<\/p>\n
The start of course is the “yum -y install webacula”. Do that first.<\/p>\n
That will amongst other things place an install guide \/usr\/share\/doc\/webacula\/docs\/INSTALL, I skimmed it to find the minimum steps needed to get this working. Not all the changes required were in the INSTALL file anyway.<\/p>\n
This post is the steps I needed to take to get it installed on my bacula server.<\/p>\n
The database tables needed to be manually created. Thats perfectly normal for any package and that step worked well.<\/p>\n
Edit the supplied scripts to create the database and tables and run them, no problems there.<\/p>\n
\r\n\/usr\/share\/webacula\/install\/webacula_mysql_create_database.sh\r\n\/usr\/share\/webacula\/install\/webacula_mysql_make_tables.sh\r\n<\/pre>\nAlso while fiddling around in there this is a good time to update the bacula database-name\/user\/password to whatever is used by your bacula databse; thats in the file below<\/p>\n
\r\n\/usr\/share\/webacula\/application\/config.ini\r\n<\/pre>\nAfter the tables were created and the config file updated it should all just work right.
\nWrong. I had to go through the additional steps below <\/p>\n(2) update apache config to allow access<\/h2>\n
The first issue was I could not browse to the application URL.<\/p>\n
In the installed \/etc\/httpd\/conf.d\/webacula.conf file the following lines were commented. So the global apache settings did not permit access to the application.<\/p>\n
\r\n# AuthType Basic\r\n# AuthName \"Webacula\"\r\n# AuthUserFile \/etc\/httpd\/conf\/webacula.users\r\n# Require valid-user\r\n<\/pre>\nI added below those four lines<\/p>\n
\r\n Require all granted\r\n<\/pre>\nOn a production site you might want to instead uncomment the lines and create a htpasswd file for the AuthUserFile to use.
\nHowever for a home network you will also notice in that file it denies access from all servers except localhost. I just added my two desktop servers to the allow list which is enough to control local access.<\/p>\n(3) Install mysql Zend driver<\/h2>\n
The next issue was the PDO driver for mysql was not installed. As determined by the fortunately verbose error message in the apache error_log file<\/p>\n
\r\n[Sun Jun 29 11:17:32.852494 2014] [:error] [pid 11092] [client 192.168.1.187:1905] PHP Fatal error: Uncaught exception 'Zend_Exception' with message 'File \"Zend\/Db\/Adapter\/Pdo\/Mysql.php\" does not exist or class \"Zend_Db_Adapter_Pdo_Mysql\" was not found in the file' in \/usr\/share\/php\/Zend\/Loader.php:87\\nStack trace:\\n#0 \/usr\/share\/php\/Zend\/Db.php(263): Zend_Loader::loadClass('Zend_Db_Adapter...')\\n#1 \/usr\/share\/webacula\/html\/index.php(103): Zend_Db::factory('PDO_MYSQL', Array)\\n#2 {main}\\n thrown in \/usr\/share\/php\/Zend\/Loader.php on line 87\r\n<\/pre>\nThat had to be manually installed.<\/p>\n
\r\nyum -y install php-ZendFramework-Db-Adapter-Pdo-Mysql\r\n<\/pre>\n(4) The repo version of webacula is out of date<\/h2>\n
The next issue was the repo version of webacula was for a much earlier version of bacula, the repo files are not compatible with each other. A very clear error message in the apache error_log file.<\/p>\n
\r\n[Sun Jun 29 11:31:14.940417 2014] [:error] [pid 11092] [client 192.168.1.187:1942] PHP Fatal error: Uncaught exception 'Zend_Exception' with message 'Version error for Catalog database (wanted 12, got 14) ' in \/usr\/share\/webacula\/html\/index.php:183\\nStack trace:\\n#0 {main}\\n thrown in \/usr\/share\/webacula\/html\/index.php on line 183\r\n<\/pre>\nBoth bacula and webacula were installed from the Fedora repositories. An update showed I have the latest webacula; so the repository versions are out of step.
\n[root@vmhost1 application]# yum update webacula
\nLoaded plugins: langpacks, refresh-packagekit
\nNo packages marked for update<\/p>\nDefinately a risk as obviously the underlying bacula tables are a much later version, but I manually changed the hard coded version the script expected to the version number in the bacula database.
\nIn file \/usr\/share\/webacula\/html\/index.php I changed the below to get past that error.<\/p>\n\r\ndefine('BACULA_VERSION', 14); \/\/ Bacula Catalog version *MID CHANGE FROM 12 TO 14\r\n<\/pre>\n(5) Setup SUDO access for bconsole<\/h2>\n
The final change needed is that by default when installed webacula wants to use sudo to access bconsole; so “visudo” and add at the end of the file<\/p>\n
\r\n# for webacula\r\nDefaults:apache !requiretty\r\n%apache localhost=NOPASSWD: \/sbin\/bconsole\r\n%apache realhostname=NOPASSWD: \/sbin\/bconsole\r\n<\/pre>\nAn important note on the above; on my server the localhost entry did not work even though the http server is listening on all interfaces, which is why I added the second %apache entry, change realhostname to the real host name of the server you are installing webacula on.<\/p>\n
(6) Try it, it should work now<\/h2>\n
Restart the https server to pick up the changes you have been making. Then point your browser at the \/webacula URL you configured. All done.<\/p>\n
Summary<\/h2>\n
For me the bad news is I have been trying to remember what web interface I used to use to manage my bacula server; and installing various packages to find the functionality I want. This was not it unfortunately. <\/p>\n
The restore functionality of webacula is pretty impressive so I won’t be un-installing it just yet, as I’ve made a few typos on command line restores before. But I doubt I will use it for anything else.<\/p>\n
So back to the bconsole command line for me.<\/p>\n","protected":false},"excerpt":{"rendered":"
