1.安装JAVA

下载Linux环境下的jdk1.8

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

目前在官网下载低于jdk1.8的java jdk的时候需要登陆，这边分享一个账号，方便下载账号：2696671285@qq.com 密码：Oracle123 账号提供者：https://blog.csdn.net/WNsshssm/article/details/84315519

# 在/root下创建java8目录
mkdir java8
# 解压文件到java8
tar zxvf jdk-8u241-linux-x64.tar.gz -C /root/java8
#修改配置文件
vim /etc/profile
export JAVA_HOME=/root/java8/jdk1.8.0_241
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
#更新环境变量
source /etc/profile
# 如果报错/root/java8/jdk1.8.0_241/bin/javac: /lib/ld-linux.so.2: bad ELF interprete
sudo yum install glibc.i686
# javac验证是否安装成功

2.安装Mysql

wget 'https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm'

sudo rpm -Uvh mysql57-community-release-el7-11.noarch.rpm

yum repolist all | grep mysql

sudo yum install mysql-community-server

启动mysql服务

sudo service mysqld start

sudo systemctl start mysqld

sudo systemctl status mysqld

查看系统默认的root密码

grep "temporary password" /var/log/mysqld.log

mysql -u root -p输入密码后进入MySQL修改默认密码：

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root'(密码改成了root)

修改密码会提示校验不通过先执行:set global validate_password_policy=0;

PS:注意本地安装Navicat连接远程服务器的时候，会被拒绝这时需要在服务器端运行授权：

grant all privileges on *.*  to  'root'@'%' identified by 'root';

flush privileges;

3.创建jira数据库

create database jira default character set utf8 collate utf8_bin;

4.安装Jira

#下载jira
wget https://downloads.atlassian.com/software/jira/downloads/atlassian-jira-soft
#更改权限
 chmod 755 atlassian-jira-software-7.3.8-x64.bin
 #安装jira
./atlassian-jira-software-7.3.8-x64.bin
