1、jdk1.8 检查 yum 中有没有 java1.8 包

yum list java-1.8*

开始安装

yum install java-1.8.0-openjdk* -y

2、安装redis https://www.cnblogs.com/hjw-zq/p/9778514.html

yum install redis

yum install epel-release

systemctl start redis

systemctl status redis

自启动

systemctl enable redis 

安装数据库

1、安装RPM

yum install https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm

2、安装客户端

yum install postgresql11

3、安装依赖包

yum install postgresql11-libs

yum install postgresql11-contrib

yum install postgresql11-devel

4、安装服务器端

yum install postgresql11-server

5、数据初始化与启动

/usr/pgsql-11/bin/postgresql-11-setup initdb

systemctl enable postgresql-11

systemctl start postgresql-11

6、修改密码

passwd postgres

上面的方法无法安装的时候使用下面这种

sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

rpm -qi pgdg-redhat-repo

sudo dnf module disable postgresql

sudo dnf clean all

sudo dnf -y install postgresql11-server postgresql11

dnf info postgresql11-server postgresql11

修改可访问配置

vim /var/lib/pgsql/11/data/postgresql.conf

listen_addresses = ‘*’

port = 5432

vim /var/lib/pgsql/11/data/pg_hba.conf

host all all 0.0.0.0/0 md5

systemctl restart postgresql-11

安装nginx

sudo yum install nginx

sudo systemctl enable nginx

sudo systemctl start nginx

脚本自启动

方法一：

chmod +x /etc/rc.d/init.d/yourService

cd /etc/rc.d/init.d 

chkconfig --add yourService.sh 

chkconfig yourService.sh on

方法二：（此方法可以正常开机执行，且不会每次登录都执行，推荐）
自己写的脚本：yourService.sh

vim /etc/init.d/yourService.sh
chmod +x /etc/init.d/yourService.sh
chkconfig --add yourService.sh 
chkconfig yourService.sh on
