CentOS7安装mariaDB、jdk1.8、redis数据库例子

作者:袖梨 2022-06-29


这个是centos7自带的数据库MariaDB,以前是mysql,到7以后,改为MariaDB。。。

 

1. MariaDB安装,没有往深处配置。。。懒得动了。。参考:http://blog.csdn.net/default7/article/details/41973887

    a:yum install mariadb mariadb-server

    b:systemctl start mariadb ==> 启动mariadb

    c:systemctl enable mariadb ==> 开机自启动

    d:mysql_secure_installation ==> 设置 root密码等相关

    e:mysql -uroot -p123456 -h127.0.0.1 ==> 测试登录!

 

2. jdk安装。

  换汤不换药,三部曲;1. 下载,2.看装过没,3. 安装&配置环境

  rpm安装法,不会的去百度。。。很简单的。。上面参考的教程也有。

3. redis

  安装必要包:

yum install gcc

下载:ps:如果没有wget命令,执行:yum install wget;(这个方案是通用的,如果有命令没有安装,一般这种办法都可以安装出来的。。我挺喜欢这个功能的。。)

wget http://download.redis.io/releases/redis-3.2.3.tar.gz

解压:

tar zxvf redis-3.2.3.tar.gz

进入目录,分配内存:  

 cd redis-3.2.3      # 进入目录

 make MALLOC=libc    # 不执行,会报错。

配置系统启动:./utils/install_server.sh

[root@localhost redis-3.2.3]# ./utils/install_server.sh
