Introduction

This guide covers the installation of Jira and Confluence on CentOS 7.4. The instructions are based on Jira version 9.11.3 and Confluence version 8.6.1, but the process is similar for other versions.

Prerequisites

• A CentOS 7.4 system
• Basic Linux command-line knowledge
• Java installed

System Time Verification

Check the system date with the following command:

date

If the date is incorrect, update it using:

yum -y install ntp ntpdate
ntpdate cn.pool.ntp.org
date

Installation Steps

1. Install Java

yum install java -y

2. Create Directory and Download Files

Install wget if not already installed:

yum install wget -y

Create a directory and download the necessary files:

mkdir /atlassian
cd /atlassian
wget http://file.xujian.tech/atlassian-agent.jar
wget https://product-downloads.atlassian.com/software/jira/downloads/atlassian-jira-software-8.20.7-x64.bin

3. Install Jira

Make the binary executable and run it:

chmod u+x atlassian-jira-software-8.20.7-x64.bin
./atlassian-jira-software-8.20.7-x64.bin

During installation, press Enter to accept all default options.

4. Modify setenv.sh

Navigate to the Jira bin directory and edit the setenv.sh file:

cd /opt/atlassian/jira/bin
vi setenv.sh

Add the following line at the end of the file:

export JAVA_OPTS="-javaagent:/atlassian/atlassian-agent.jar ${JAVA_OPTS}"

5. Install and Configure MySQL

Install MySQL 5.7 and configure it for Jira. Modify the my.cnf file:

vi /etc/my.cnf

Add the following under the [mysqld] section:

default-storage-engine=INNODB
max_allowed_packet=256M
innodb_log_file_size=256M
character_set_server=utf8mb4
innodb_default_row_format=DYNAMIC
innodb_large_prefix=ON
innodb_file_format=Barracuda
transaction-isolation=READ-COMMITTED

Create a database for Jira:

CREATE DATABASE jira CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;

Restart MySQL:

service mysqld restart

6. Copy MySQL Driver to Jira

Download the MySQL connector and place it in the Jira lib directory:

cd /opt/atlassian/jira/lib
wget http://file.xujian.tech/mysql-connector-java-5.1.49.jar

7. Restart Jira

Stop and start the Jira service:

service jira stop
service jira start

To avoid access issues, disable the firewall or open port 8080:

systemctl stop firewalld.service
