#=================================================
# 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"

# STANDARD MODIFICATIONS
#=================================================
# FIND AND OPEN A PORT
#=================================================

### Use these lines if you have to open a port for the application
### `ynh_find_port` will find the first available port starting from the given port.
### If you're not using these lines:
###		- Remove the section "CLOSE A PORT" in the remove script

# Find a free port
#port=$(ynh_find_port 8095)

#ynh_app_setting_set $app port $port

#=================================================
# INSTALL DEPENDENCIES
#=================================================

### `ynh_install_app_dependencies` allows you to add any "apt" dependencies to the package.
### Those deb packages will be installed as dependencies of this package.
### If you're not using this helper:
###		- Remove the section "REMOVE DEPENDENCIES" in the remove script
###		- As well as the section "REINSTALL DEPENDENCIES" in the restore script
###		- And the section "UPGRADE DEPENDENCIES" in the upgrade script

# CREATE A MYSQL DATABASE
#=================================================

### Use these lines if you need a database for the application.
### `ynh_mysql_setup_db` will create a database, an associated user and a ramdom password.
### The password will be stored as 'mysqlpwd' into the app settings,
### and will be available as $db_pwd
### If you're not using these lines:

#=================================================
# DOWNLOAD, CHECK AND UNPACK SOURCE
#=================================================

### `ynh_setup_source` is used to install an app from a zip or tar.gz file,
### downloaded from an upstream source, like a git repository.
### `ynh_setup_source` use the file conf/app.src

ynh_app_setting_set $app final_path $final_path
# Download, check integrity, uncompress and patch the source from app.src
#ynh_setup_source "$final_path"

#=================================================
# 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
#=================================================

### `ynh_add_fpm_config` is used to set up a PHP config.
### You can remove it if your app doesn't use PHP.
### `ynh_add_fpm_config` will use the files conf/php-fpm.conf and conf/php-fpm.ini
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "BACKUP THE PHP-FPM CONFIGURATION" in the backup script
###		- Remove also the section "REMOVE PHP-FPM CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE PHP-FPM CONFIGURATION" in the restore script
###		With the reload at the end of the script.
###		- And the section "PHP-FPM CONFIGURATION" in the upgrade script

# Create a dedicated php-fpm config
ynh_add_fpm_config

#=================================================
# SPECIFIC SETUP
#=================================================
# ...
#=================================================

#=================================================
# SETUP SYSTEMD
#=================================================

### `ynh_systemd_config` is used to configure a systemd script for an app.
### It can be used for apps that use sysvinit (with adaptation) or systemd.
### Have a look at the app to be sure this app needs a systemd script.
### `ynh_systemd_config` will use the file conf/systemd.service
### If you're not using these lines:
###		- You can remove those files in conf/.
###		- Remove the section "BACKUP SYSTEMD" in the backup script
###		- Remove also the section "STOP AND REMOVE SERVICE" in the remove script
###		- As well as the section "RESTORE SYSTEMD" in the restore script
###		- And the section "SETUP SYSTEMD" in the upgrade script

# Create a dedicated systemd config
#ynh_add_systemd_config

#=================================================
# SETUP APPLICATION WITH CURL
#=================================================

### Use these lines only if the app installation needs to be finalized through
### web forms. We generally don't want to ask the final user,
### so we're going to use curl to automatically fill the fields and submit the
### forms.

# Set right permissions for curl install
#chown -R www-data: $final_path

# Set the app as temporarily public for curl call
#ynh_app_setting_set $app skipped_uris "/"

# Reload SSOwat config
yunohost app ssowatconf

# Reload Nginx
systemctl reload nginx

# Installation with curl
#ynh_local_curl "/INSTALL_PATH" "key1=value1" "key2=value2" "key3=value3"

# Remove the public access
if [ $is_public -eq 0 ]
then
	ynh_app_setting_delete $app skipped_uris
fi

#=================================================
# MODIFY A CONFIG FILE
#=================================================

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

echo "<?php
// Zabbix GUI configuration file.
global \$DB;

\$DB['TYPE']     = 'MYSQL';
\$DB['SERVER']   = 'localhost';
\$DB['PORT']     = '0';

\$DB['USER']     = '"$db_user"';
\$DB['PASSWORD'] = '"$db_pwd"';

// Schema name. Used for IBM DB2 and PostgreSQL.
\$DB['SCHEMA'] = '';

\$ZBX_SERVER      = 'localhost';
\$ZBX_SERVER_PORT = '10051';
\$ZBX_SERVER_NAME = 'zabbix-server';

\$IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG;">/usr/share/zabbix/conf/zabbix.conf.php

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

sed -i "s/DBName=zabbix/DBName=$db_name/g"  /etc/zabbix/zabbix_server.conf
sed -i "s/DBUser=zabbix/DBUser=$db_user/g"   /etc/zabbix/zabbix_server.conf
sed -i "126a DBPassword=$db_pwd"  /etc/zabbix/zabbix_server.conf

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

#=================================================
# STORE THE CONFIG FILE CHECKSUM
#=================================================

### `ynh_store_file_checksum` is used to store the checksum of a file.
### That way, during the upgrade script, by using `ynh_backup_if_checksum_is_different`,
### you can make a backup of this file before modifying it again if the admin had modified it.

# Calculate and store the config file checksum into the app settings
#ynh_store_file_checksum "$final_path/CONFIG_FILE"

#=================================================
# GENERIC FINALIZATION
#=================================================
# SECURE FILES AND DIRECTORIES
#=================================================

### For security reason, any app should set the permissions to root: before anything else.
### Then, if write authorization is needed, any access should be given only to directories
### that really need such authorization.

# Set permissions to app files
#chown -R root: $final_path

#=================================================
# 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

#=================================================
# ADVERTISE SERVICE IN ADMIN PANEL
#=================================================

### `yunohost service add` is a CLI yunohost command to add a service in the admin panel.
### You'll find the service in the 'services' section of YunoHost admin panel.
### This CLI command would be useless if the app does not have any services (systemd or sysvinit)
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "REMOVE SERVICE FROM ADMIN PANEL" in the remove script
###		- As well as the section ADVERTISE SERVICE IN ADMIN PANEL" in the restore script

#yunohost service add NAME_INIT.D --log "/var/log/FILE.log"

#=================================================
# 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 "/"
fi

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

systemctl reload nginx
