### If it's a multi-instance app, meaning it can be installed several times independently
### The id of the app as stated in the manifest is available as $YNH_APP_ID
### The instance number is available as $YNH_APP_INSTANCE_NUMBER (equals "1", "2", ...)
### The app instance name is available as $YNH_APP_INSTANCE_NAME
###    - the first time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample
###    - the second time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample__2
###    - ynhexample__{N} for the subsequent installations, with N=3,4, ...
### The app instance name is probably what interests you most, since this is
### guaranteed to be unique. This is a good unique identifier to define installation path,
### db names, ...

#=================================================
# CHECK IF THE APP CAN BE INSTALLED WITH THESE ARGS
#=================================================

### If the app uses nginx as web server (written in HTML/PHP in most cases), the final path should be "/var/www/$app".
### If the app provides an internal web server (or uses another application server such as uwsgi), the final path should be "/opt/yunohost/$app"

# NGINX CONFIGURATION
#=================================================

### `ynh_add_nginx_config` will use the file conf/nginx.conf

# Create a dedicated nginx config
ynh_add_nginx_config

#=================================================
# CREATE DEDICATED USER
#=================================================

# Create a system user
#ynh_system_user_create $app

#=================================================
# PHP-FPM CONFIGURATION
#=================================================

# Reload SSOwat config

# Reload Nginx
systemctl reload nginx

# Remove the public access

then
	ynh_app_setting_delete $app skipped_uris

ynh_mysql_connect_as $db_name $db_pwd $db_name < ./db.sql

#=================================================
# Restore configs files
#=================================================

### `ynh_replace_string` is used to replace a string in a file.
### (It's compatible with sed regular expressions syntax)

ynh_restore_file "/usr/share/zabbix/conf/zabbix.conf.php"

chown -R www-data. /usr/share/zabbix

ynh_restore_file "/etc/zabbix"

systemctl enable zabbix-server && systemctl start zabbix-server




#=================================================
# SETUP LOGROTATE
#=================================================

### `ynh_use_logrotate` is used to configure a logrotate configuration for the logs of this app.
### Use this helper only if there is effectively a log file for this app.
### If you're not using this helper:
###		- Remove the section "BACKUP LOGROTATE" in the backup script
###		- Remove also the section "REMOVE LOGROTATE CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE LOGROTATE CONFIGURATION" in the restore script
###		- And the section "SETUP LOGROTATE" in the upgrade script

# Use logrotate to manage application logfile(s)
ynh_use_logrotate

#=================================================
# SETUP SSOWAT
#=================================================

# Make app public if necessary
if [ $is_public -eq 1 ]
then
	# unprotected_uris allows SSO credentials to be passed anyway.
	ynh_app_setting_set $app unprotected_uris "/"

#=================================================
# RELOAD NGINX
#=================================================

systemctl reload nginx
