 3 | Install Zabbix is a set of scripts to install/upgrade Zabbix 6.4.x from source on Ubuntu
 4 | 22.04 and probably other Debian derived distributions. You can of course use
 5 | various methods to install Zabbix Server, but this method gives you the ultimate
 6 | flexibility. In addition, there are no deb packages for ARM32 based platforms hence
 7 | building from source is the only method. The scripts allow:
 8 | * Install and secure MySQL server
 9 | * Import Zabbix data into MySQL
10 | * Install Java 17 JDK for the Java gateway and enable in build
11 | * Patch source to fix "plugins/proc/procfs_linux.go:248:6: constant 1099511627776 overflows int" on 32 bit systems
12 | * Install Zabbix Server
13 | * Create zbx_monitor user for local MySQL monitoring (just configure and add 'Template DB MySQL by Zabbix agent 2' template to 'Zabbix server')
14 | * Install Zabbix Agent 2
15 | * Create systemd services for both Zabbix Server and Agent 2
16 | * Move MySQL data directory (optional)
17 | * Install Zabbix Agent 2 on clients (optional)
18 | 
19 | **Important note:** Before upgrading Zabbix see [Upgrade from sources](https://www.zabbix.com/documentation/current/en/manual/installation/upgrade/sources). 
20 | To be on the safe side I would [export](https://www.zabbix.com/documentation/current/en/manual/xml_export_import) Zabbix
21 | server configuration, shut down Zabbix server service and [backup](https://linuxconfig.org/linux-commands-to-backup-and-restore-mysql-database)
22 | MySQL database. If you are using a VM just make a snapshot before upgrading and rollback 
23 | if you have problems. As always, you should test upgrade on a VM first if possible.
24 | 
25 | **Upgrading error** If you get ```The Zabbix database version does not match current requirements. Your database version: 6010048. Required version: 6020000. Please contact your system administrator.```
26 | in UI and ```[Z3005] query failed: [1419] You do not have the SUPER privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable) [create trigger hosts_insert after insert on hosts``` 
27 | in log.
28 | * `sudo service zabbix-server stop`
29 | * `sudo mysql -u root`
30 | * `SET GLOBAL log_bin_trust_function_creators = 1;`
31 | * `commit;`
32 | * `quit`
33 | * `sudo service zabbix-server start`
34 | * Check /tmp/zabbix_server.log
35 | 
36 | More [configuration](https://techexpert.tips/category/zabbix) options!
37 | 
38 | ## Download project
39 | * `cd ~/`
40 | * `git clone --depth 1 https://github.com/sgjava/install-zabbix.git`
41 | 
42 | ## Install script
43 | This assumes a fresh OS install. You should try the scripts out on a VM to play
44 | with configuration prior to doing final install. Upgrade is performed if existing
45 | install detected and configuration is saved to `/usr/local/etc/zabbix_server.conf.bak`
46 | and `/usr/local/etc/zabbix_agent2.conf.bak`
47 | * `cd ~/install-zabbix/scripts`
48 | * Change configuration values as needed
49 | * `./install.sh`
50 | * Check log file for errors
51 | * Navigate to http://hostname/zabbix
52 | * Get DB password from script and finalize front end configuration
53 | * Login using Admin/zabbix
54 | 
55 | To stop and start Zabbix server
56 | * `sudo service zabbix-server stop`
57 | * `sudo service zabbix-server start`
58 | 
59 | ## Move DB script
60 | This assumes you ran install.sh above. It's handy to move the MySQL data directory
61 | to a NFS share if you are running Zabbix Server off an SD card for instance.
62 | * `cd ~/install-zabbix/scripts`
63 | * Change configuration values as needed
64 | * `./movedb.sh`
65 | * Check log file for errors
66 | 
67 | If you plan on using a NFS mount for your MySQL data directory you will need to
68 | do the following:
69 | * `sudo nano /etc/systemd/system/multi-user.target.wants/mysql.service`
70 | * Add `remote-fs.target` to `After`
71 | * Add `RequiresMountsFor=/your/mount/dir` to `[Unit]` section
72 | * `sudo systemctl daemon-reload`
73 | 
74 | To stop and start MySQL server
75 | * `sudo service mysql stop`
76 | * `sudo service mysql start`
77 | 
78 | These changes can be removed during `apt upgrade`, so if you see mysql fail to start after reboot add service changes back in. 
79 | 
80 | ## Install Agent 2 script
81 | Install Zabbix Agent 2 script on client. Make sure to change configuration to point to
82 | your Zabbix server before running. You can always configure manually should you forget.
83 | Upgrade is performed if existing install detected and configuration is saved to `/usr/local/etc/zabbix_agent2.conf.bak`
84 | * `cd ~/install-zabbix/scripts`
85 | * Change configuration values as needed
86 | * `./install-agent2.sh`
87 | * Check log file for errors
88 | 
89 | To stop and start Zabbix Agent 2
90 | * `sudo service zabbix-agent2 stop`
91 | * `sudo service zabbix-agent2 start`
92 |
