[root@sht-sgmhadoopdn-04 java]# vi /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_111
export path=$JAVA_HOME/bin:$PATH
[root@sht-sgmhadoopdn-04 java]# source /etc/profile

#2.安装 redis 3.2.5
2.1 安装编绎所需包gcc,tcl
[root@sht-sgmhadoopdn-04 local]# yum install gcc
[root@sht-sgmhadoopdn-04 local]# yum install tcl

2.2 下载redis-3.2.5
[root@sht-sgmhadoopdn-04 local]# wget http://download.redis.io/releases/redis-3.2.5.tar.gz

2.3 安装redis
[root@sht-sgmhadoopdn-04 local]# mkdir /usr/local/redis
[root@sht-sgmhadoopdn-04 local]# tar xzvf redis-3.2.5.tar.gz
[root@sht-sgmhadoopdn-04 local]# cd redis-3.2.5
[root@sht-sgmhadoopdn-04 redis-3.2.5]# make PREFIX=/usr/local/redis install
[root@sht-sgmhadoopdn-04 redis-3.2.5]# cd ../
[root@sht-sgmhadoopdn-04 redis-3.2.5]# ll /usr/local/redis/bin/
total 15056
-rwxr-xr-x 1 root root 2431728 Nov 12 20:45 redis-benchmark
-rwxr-xr-x 1 root root   25165 Nov 12 20:45 redis-check-aof
-rwxr-xr-x 1 root root 5182191 Nov 12 20:45 redis-check-rdb
-rwxr-xr-x 1 root root 2584443 Nov 12 20:45 redis-cli

-rwxr-xr-x 1 root root 5182191 Nov 12 20:45 redis-server

2.4 配置redis为服务
[root@server redis-3.2.5]# cp utils/redis_init_script /etc/rc.d/init.d/redis
[root@server redis-3.2.5]# vi /etc/rc.d/init.d/redis
在第二行添加：#chkconfig: 2345 80 90
EXEC=/usr/local/bin/redis-server  修改成 EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli  修改成 CLIEXEC=/usr/local/redis/bin/redis-cli
CONF="/etc/redis/${REDISPORT}.conf" 修改成 CONF="/usr/local/redis/conf/${REDISPORT}.conf"
$EXEC $CONF 修改成  $EXEC $CONF &

[root@server redis-3.2.5]# mkdir /usr/local/redis/conf/
[root@server redis-3.2.5]# chkconfig --add redis
[root@server redis-3.2.5]# cp redis.conf /usr/local/redis/conf/6379.conf
[root@server redis-3.2.5]# vi /usr/local/redis/conf/6379.conf
daemonize yes
pidfile /var/run/redis_6379.pid
bind 172.16.101.66

2.5 启动redis
[root@server redis-3.2.5]# cd ../redis
[root@sht-sgmhadoopdn-04 redis]# service redis start
Starting Redis server...
[root@sht-sgmhadoopdn-04 redis]# netstat -tnlp|grep redis
tcp        0      0 172.16.100.79:6379      0.0.0.0:*               LISTEN      30032/redis-server 
[root@sht-sgmhadoopdn-04 redis]

#2.6 添加环境变量
[root@sht-sgmhadoopdn-04 redis]# vi /etc/profile
export REDIS_HOME=/usr/local/redis
export PATH=$REDIS_HOME/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
[root@sht-sgmhadoopdn-04 redis]# source /etc/profile
[root@sht-sgmhadoopdn-04 redis]# which redis-cli
/usr/local/redis/bin/redis-cli

2.7 Test and set password (no password is set in this experiment)
[root@sht-sgmhadoopdn-04 redis]# redis-cli -h sht-sgmhadoopdn-04
sht -sgmhadoopdn-04:6379>
sht-sgmhadoopdn-04:6379> set testkey testvalue
OK
sht-sgmhadoopdn-04:6379> get test
(nil)
sht-sgmhadoopdn -04:6379> get testkey
"testvalue"
sht-sgmhadoopdn-04:6379>

[root@sht-sgmhadoopdn-04 redis]# vi /usr/local/redis/conf /6379.conf
/*Add a verification password*/
requirepass 123456

[root@sht-sgmhadoopdn-04 redis]# service redis stop
[ root@sht-sgmhadoopdn-04 redis]# service redis start

[root@sht-sgmhadoopdn-04 redis]# redis-cli -h sht-sgmhadoopdn-04
sht-sgmhadoopdn-04:6379> ; set key ss
(error) NOAUTH Authentication required.
[root@server redis-3.2.5]# redis-cli -h sht-sgmhadoopdn-04 -a 123456
sht-sgmhadoopdn-04: 6379> set a b
OK
sht-sgmhadoopdn-04:6379> get a
"b"
sht-sgmhadoopdn-04:6379> exit;
