从0开始学CentOS7(2)---安装mariaDB、jdk1.8、redis
继续前面的基础步骤~
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

Redis服务查看、开启、关闭
1、通过ps -ef|grep redis命令查看Redis进程;
2、开启Redis服务操作通过/etc/init.d/redis_6379 start命令,也可通过(service redis_6379 start);
3、关闭Redis服务操作通过/etc/init.d/redis_6379 stop命令,也可通过(service redis_6379 stop);
