MySQL Server installation
The CentOS 8 AppStream repository only contain MySQL 8.0 packages, so, to install MySQL 5.7, we need to do some prep-work.
Disable MySQL default AppStream repository.
Code Block sudo yum install mariadb-server
Create a new repository file..
Code Block sudo vi /etc/yum.repos.d/mysql-community.repodnf remove @mysql sudo dnf module reset mysql && sudo dnf module disable mysql
Create a new repository file..
Code Block sudo vi /etc/yum.repos.d/mysql-community.repo
Paste the following dat into the new repo file.
Code Block [mysql57-community] name=MySQL 5.7 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/ enabled=1 gpgcheck=0 [mysql-connectors-community] name=MySQL Connectors Community baseurl=http://repo.mysql.com/yum/mysql-connectors-community/el/7/$basearch/ enabled=1 gpgcheck=0 [mysql-tools-community] name=MySQL Tools Community baseurl=http://repo.mysql.com/yum/mysql-tools-community/el/7/$basearch/ enabled=1 gpgcheck=0
Disable MySQL 8 repository.
Code Block sudo vi /etc/yum.repos.d/mysql-community.repodnf config-manager --disable mysql80-community
Enable repository for MySQL 5.7.
Code Block sudo dnf config-manager --enable mysql57-community
Install MySQL 5.7.
Code Block sudo dnf install mysql-community-server
...
- Download the MySQL JDBC driver version 58.0.123.
Move the downloaded
.zip
archive to/home/flexbi
directory on your server and then run the following command to unzip the archive (file name in the example can differ from the actual file depending on the software version):Code Block unzip mysql-connector-java-58.10.4923.zip
Copy the
.jar
file from the newly created folder to the/home/flexbi/flexbi_private/lib
directory (if it doesn't exist, create it). Run the following command to achieve that (file name in the example can differ from the actual name depending on the software version):Code Block cp mysql-connector-java-58.10.4923/mysql-connector-java-58.10.49-bin23.jar flexbi_private/lib/
Setup and configuration
...
If you have large amount of records, we suggest to adjust the database engine performance by editing
/etc/my.conf cnf
file using appropriate values.
The following is an example of a good performance configuration that you can insert under the [mysqld]
part of the configuration file:Code Block innodb_buffer_pool_size = 1024M innodb_log_file_size = 256M query_cache_size= 16M query_cache_type = 1 max_connections = 200
Note If you change the log file size after starting the MySQL server, you have to delete
id_logfile0
andid_logfile1
file from/var/lib/mysql
directory.Note Adjust the
innodb_buffer_pool_size
to a level that you can actually afford on your server, taking into account Java and other application memory needRun the following command to start MySQL Server and ensure that it will be automatically started during server startup:
Code Block systemctl enable --now mysqld.service
Run the following command, to get the automatically generated MySQL Server
root
user password:Code Block sudo grep 'A temporary password' /var/log/mysqld.log |tail -1
Make note of the password shown on screen.
Start MySQL Secure Installation to change the
root
password, Disallow root login remotely, remove anonymous users and remove test database.Code Block sudo mysql_secure_installation
Connect to MySQL Database as
root
user, using the new password.Code Block mysql -u root -p
Run the following commands, to create a flex.bi user named
flexbi_private
: (Exchangesecret
with the actual password you want to use.)Code Block CREATE USER 'flexbi_private'@'localhost' IDENTIFIED BY 'secret'; GRANT ALL PRIVILEGES ON `flexbi_private%`.* TO 'flexbi_private'@'%' IDENTIFIED BY 'secret'; FLUSH PRIVILEGES;
Firewall configuration
By default flex.bi Enterprise runs on the port 8080
, so you should open ths port in your firewall.
To do this, follow these instructions:
Run the following command to open the port
8080
:Code Block firewall-cmd --permanent --add-port=8080/tcp
Run the following command to reload the firewall:
Code Block firewall-cmd --reload
Run the following command to check if the port is open:
Code Block firewall-cmd --list-ports
Google Chrome Installation
flex.bi uses Google Chrome for report exports, so for this feature to work you have to install Google Chrome.
Do do this, follow these instructions:
Get Google Chrome rpm.
Code Block wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
Install Google Chrome from the .rpm file you just downloaded.
sudo dnf localinstall google-chrome-stable_current_x86_64.rpmCode Block the .rpm file you just downloaded.
Code Block sudo dnf localinstall google-chrome-stable_current_x86_64.rpm
Centos 8 configuration
To ensure full functionality of the flex.bi Enterprise, you have to change the default Centos 8 crypto policy level to LEGACY.
To do this, run the following command:
Code Block |
---|
update-crypto-policies --set LEGACY |
flex.bi Enterprise configuration
The main tool for flex.bi Enterprise configuration is the Configure the eazybi.toml
file located in the /config
folder in your flex.bi direcotry.
Run the following command, to copy the
eazybi.toml.sample
file in the/config
folder to a new file namedeazybi.toml
:Code Block cp /home/flexbi/flexbi_private/config/eazybi.toml.sample /home/flexbi/flexbi_private/config/eazybi.toml
In a text editor of your choice, open the newly created
eazybi.toml
file and make the necessary configurations:Add licence information:
Code Block [license] name = "Organization name" key = """ Paste license key here """
Configure general parameters, like, time zone, user registration, account creation etc.
Code Block [general] # By default local server time zone will be used. Specify different if necessary. # time_zone = "Europe/Riga" # Uncomment to allow account creation only to system admins. # disable_account_creation = true # Uncomment to disable user registration. # disable_user_registration = true ......
Specify default URL parameters like host and port for accessing your flex.bi Enterprise installation:
Code Block [default_url_options] # This example is for the default http://localhost:8080 URL. host = "localhost" port = 8080 # This example is for the https://example.com URL. # host = "example.com" # protocol = "https"
Specify Mailer parameter, to set the e-mail address that will be used as the sender address for communication from the flex.bi Enterprise.
Code Block [mailer] from = "noreply@example.com"
Configure SMPT parameters for sending out e-mails from flex.bi Enterprise.
Code Block [mailer.smtp] # address = "smtp.gmail.com" # port = "587" # domain = "example.com" # user_name = "noreply@example.com" # password = "secret" # authentication = "plain" # enable_starttls_auto = true
- Add a
systemd
initialization script for starting flex.bi service.Copy the sample initialization script from the
/bin/systemd
directory of the flex.bi installation folder to the/etc/systemd/system/
directory in your server.Code Block cp /home/flexbi/flexbi_private/bin/systemd/flexbi.service /etc/systemd/system/
Open the file with a text editor of your choice and adjust the configuration to your needs.
Code Block # Sample init script for flex.bi [Unit] Description=flex.bi reporting service After=syslog.target network.target [Service] Type=simple # Run the service as this user and group User=flexbi Group=flexbi TimeoutSec=30 # Remember to change /home/flexbi/flexbi_private to the actual home directory of flex.bi in all places WorkingDirectory=/home/flexbi/flexbi_private Environment="RAILS_ENV=production" Environment="EAZYBI_HOME=/home/flexbi/flexbi_private" Environment="EAZYBI_PREFIX=/flexbi" Environment="RUBYOPT=-W0" # Adjust to available memory Environment="JAVA_OPTS=-Xmx1024m -Xms256m -Dfile.encoding=UTF-8 -Djava.awt.headless=true -Dorg.eclipse.jetty.LEVEL=OFF -Djava.io.tmpdir=/home/flexbi/flexbi_private/tmp" # Default configuration ExecStart=/usr/bin/java $JAVA_OPTS -Dwarbler.host=localhost -Dwarbler.port=8080 -jar flexbi_private.jar Restart=on-failure StandardOutput=syslog StandardError=syslog SyslogIdentifier=flexbi #LimitNOFILE=10000 [Install] WantedBy=multi-user.target
Run the following command to start flex.bi service and ensure it is started during server startup:
Code Block systemctl enable --now flexbi.service
- To ensure secure connection using https protocol, follow instructions in our documentation page HTTPS or SSL setup.
- Once the flexbi.service is started, you should be able to open the previously configured URL in your browser and start using flex.bi Enterprise.
