Part 1 of 2
Confluence supports most of the databases. In this post, we will set up confluence with MySQL database in a Linux environment. I am using ubuntu 20.04 OS.
In the first step, we will install the MySQL database.
apt install mysql-server and press y.
root@conf:~# apt install mysql-server

The database is successfully installed. now, we need to enable MySQL service on the startup, start the service and check the status.
1- systemctl enable mysql
2- systemctl start mysql
3- systemctl status mysql
root@conf:~# systemctl enable mysql
Synchronizing state of mysql.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable mysql
root@conf:~# systemctl start mysql
root@conf:~# systemctl status mysql

root@conf:~#
so, MySQL is enabled to auto-start. service is started and the status is running.
In the next step, we will create a user, and database and grant permission on the database to the created user for confluence setup.
root@conf:~# mysql

In the above screen, we created the confluence user with badminpassword password. confluence database is created with utf8mb4 character and utf8mb4_bin collate. granted all the privileges on the confluence database to the confluence user and applied the changes of permission with the flush privileges command.
Let’s check the database and the user is created and given permission is working fine. Exit from MySQL and log in using confluence credentials. And display the database.
root@conf:~# mysql -u confluence -p
Enter password:

The database is created and permission is working correctly.
We need to add some parameters or variables into the mysqld.cnf file.
root@conf:~# nano /etc/mysql/mysql.conf.d/mysqld.cnf
[mysqld]
character-set-server=utf8mb4
collation-server=utf8mb4_bin
default-storage-engine=INNODB
max_allowed_packet=256M
innodb_log_file_size=2GB
transaction-isolation=READ-COMMITTED
binlog_format=row
log_bin_trust_function_creators = 1
Before jumping to installing and configuring the confluence, we need to install JDK and set up the JAVA_HONE environment variable. Run the apt install openjdk-8-jdk command and press y.
root@conf:~# apt install openjdk-8-jdk

Check the java version and localtion.
root@conf:~# java -version
openjdk version “1.8.0_352”
OpenJDK Runtime Environment (build 1.8.0_352-8u352-ga-1~20.04-b08)
OpenJDK 64-Bit Server VM (build 25.352-b08, mixed mode)
root@conf:~# update-alternatives –list java
/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
java version is 1.8.0_352 and location is /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java.
Now, need to update-alternatives to the java location and set java home.
root@conf:~# update-alternatives –set java /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
root@conf:~# echo $JAVA_HOME
root@conf:~#
Still java home is blank. There should be a location of the java. Let,s create a java home file and set it to permanent.
root@conf:~# touch /etc/profile.d/jdk_home.sh
root@conf:~# nano /etc/profile.d/jdk_home.sh
using touch command jdk_home.sh file is created, using the nano editor below values are inserted in the jdk_home.sh file.
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$PATH:$JAVA_HOME/bin
Exit from the nano editor and reboot the system. Run the cat command to verify the changes. and echo $JAVA_HOME to check or verify the java environment is configured permanently.
root@conf:~# cat /etc/profile.d/jdk_home.sh
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$PATH:$JAVA_HOME/bin
root@conf:~#echo $JAVA_HOME
/usr/lib/jvm/java-8-openjdk-amd64
root@conf:~#
java home is configured successfully. Now, we will download, install and configure the confluence.
you can download confluence from the link below.
After finishing the download we need to extract the files.
root@conf:~# tar -xzf atlassian-confluence-7.19.3.tar.gz
root@conf:~# ls
atlassian-confluence-7.19.3 atlassian-confluence-7.19.3.tar.gz snap
root@conf:~#
we need to move the confluence extracted file to another directory. lets, ‘s make a confluence and confluence-home directory.
root@conf:~# mkdir /opt/confluence
root@conf:~# mkdir /opt/confluence-home
root@conf:~#
Remove the Atlassian .tar.gz file, move all the extracted files to the /opt/confluence directory and verify that all files are moved to the targeted directory.
root@conf:~# rm -rf atlassian-confluence-7.19.3.tar.gz
root@conf:~# mv atlassian-confluence-7.19.3/* /opt/confluence
root@conf:~# ls /opt/confluence
bin conf CONTRIBUTING.md LICENSE logs README.html README.txt RUNNING.txt temp work
BUILDING.txt confluence lib licenses NOTICE README.md RELEASE-NOTES synchrony-proxy webapps
root@conf:~#
All the files are successfully moved to the /opt/confluence directory.
