1.数据库类型
关系型：Oracle、MySQL、PostgreSQL
NOSQL：HBASE、Redis
图形：Titan
时序型：infuxdb
2.将mysql安装包发送到centOS /usr/local目录下
[root@sht-sgmhadoopnn-01 ~]# cd /usr/local
[root@sht-sgmhadoopnn-01 local]# rz mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
3.检查是否已安装
[root@sht-sgmhadoopnn-01 local]# ps -ef|grep mysqld
root 2493 2423 0 19:48 pts/3 00:00:00 grep mysqld
[root@sht-sgmhadoopnn-01 local]# rpm -qa |grep -i mysql
4.解压、重命名
[root@sht-sgmhadoopnn-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@sht-sgmhadoopnn-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql
5.创建组和用户
[root@sht-sgmhadoopnn-01 local]# groupadd -g 101 dba
[root@sht-sgmhadoopnn-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@sht-sgmhadoopnn-01 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@sht-sgmhadoopnn-01 local]# passwd mysqladmin 设置密码
if user mysqladmin is existing,please execute the following command of usermod.
[root@sht-sgmhadoopnn-01 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #
6.copy 环境变量配置文件至mysqladmin用户的home目录中
[root@sht-sgmhadoopnn-01 local]# cp /etc/skel/.* /usr/local/mysql
7.修改 /etc/my.cnf(640)
[root@sht-sgmhadoopnn-01 ~]# vi /etc/my.cnf
使用下面内容覆盖原先内容

8.赋权限
[root@sht-sgmhadoopnn-01 local]# chown mysqladmin:dba /etc/my.cnf
[root@sht-sgmhadoopnn-01 local]# chmod 640 /etc/my.cnf
[root@sht-sgmhadoopnn-01 etc]# ll my.cnf
-rw-r----- 1 mysqladmin dba 2201 Aug 25 23:09 my.cnf
[root@sht-sgmhadoopnn-01 local]# chown -R mysqladmin:dba /usr/local/mysql
[root@sht-sgmhadoopnn-01 local]# chmod -R 755 /usr/local/mysql
[root@sht-sgmhadoopnn-01 local]# su - mysqladmin
[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd
/usr/local/mysql
9.第一次安装
[mysqladmin@sht-sgmhadoopnn-01 ~]$ mkdir arch
[mysqladmin@sht-sgmhadoopnn-01 ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
10.配置 mysql 服务 and 设置开机自启
[root@sht-sgmhadoopnn-01 ~]# cd /usr/local/mysql
[root@sht-sgmhadoopnn-01 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 将服务文件拷贝到init.d下，并重命名为mysql
[root@sht-sgmhadoopnn-01 mysql]# chmod +x /etc/rc.d/init.d/mysql 赋予可执行权限
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql 删除服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql 添加服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on 设置开机自启
11.开启服务
[root@sht-sgmhadoopnn-01 mysql]# su - mysqladmin
[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd
/usr/local/mysql
[mysqladmin@sht-sgmhadoopnn-01 ~]$ rm -rf my.cnf
[mysqladmin@sht-sgmhadoopnn-01 ~]$ bin/mysqld_safe & 不要忘记，按回车键
[root@rzdatahadoop001 lib]# rpm --nodeps -e mysql-libs-5.1.71-1.el6.x86_64 先卸载
12.服务相关信息
[mysqladmin@sht-sgmhadoopnn-01 ~]$ ps -ef|grep mysqld 查看服务
[mysqladmin@sht-sgmhadoopnn-01 ~]$ netstat -tulnp | grep mysql 查看端口号
[mysqladmin@sht-sgmhadoopnn-01 ~]$ mysql 登录
mysql> show databases; 查看数据库
