hadoop2.7.2上安装hive

tar -zxf apache-hive-1.2.1-bin.tar.gz  -C ../app/
cd ../app/
ln -s apache-hive-1.2.1-bin hive

##解压安装包
tar -zxf mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz -C ../app/

##初始化
yum -y install autoconf  ##安装初始化依赖
cd ../app
ln -s mysql-5.6.24-linux-glibc2.5-x86_64 mysql

./scripts/mysql_install_db --user=hadoop --basedir=/hadoop/app/mysql --datadir=/hadoop/app/mysql/data
......
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

  /hadoop/app/mysql/bin/mysqladmin -u root password 'new-password'
  /hadoop/app/mysql/bin/mysqladmin -u root -h node1 password 'new-password'

Alternatively you can run:

  /hadoop/app/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

  cd . ; /hadoop/app/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

New default config file was created as /hadoop/app/mysql/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

[hadoop@node1 mysql]$ echo $?
0

##修改配置文件
vim /etc/my.cnf
[sudo] password for hadoop: 
[mysqld]
datadir=/hadoop/app/mysql/data
socket=/hadoop/app/mysql/data/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

user=hadoop

[mysqld_safe]
log-error=/hadoop/app/mysql/data/error.log
pid-file=/hadoop/app/mysql/data/mysql.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d


##将启动脚本添加到/etc/init.d/下
cp support-files/mysql.server /etc/init.d/mysql
vim  /etc/init.d/mysql
basedir=/hadoop/app/mysql
datadir=/hadoop/app/mysql/data


###启动mysql
service mysql start
Starting MySQL.. SUCCESS! 

##配置环境变量
vim /etc/profile
export MYSQL_HOME=/hadoop/app/mysql
export PATH=$PATH:$JAVA_HOME:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$MYSQL_HOME/bin

source /etc/profile

##修改mysql密码
mysqladmin -u root password '123' -S app/mysql/data/mysql.sock  ##-S为指定需要连接的sock文件

##修改允许的连接主机
mysql -uroot -p123 -S app/mysql/data/mysql.sock
mysql> grant all privileges on *.* to 'root'@'%' identified by '123' with grant option;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
