linux下安装redis及其中遇到的问题的解决方法

1.将下载好的压缩包放到/usr/local目录下
# tar xzf redis-3.0.2.tar.gz
# cd redis-3.0.2
# make

提示错误 make: cc: Command not found make: *** [adlist.o] Error 127
没有安装gcc环境，需要安装gcc

# yum install gcc
安装后检查是否安装成功

# rpm -qa |grep gcc
之后重新make
2.编译完成后，在Src目录下，有四个可执行文件redis-server、redis-benchmark、redis-cli和redis.conf将其拷贝到一个目录下。

# mkdir /usr/redis
# cp redis-server  /usr/redis
# cp redis-benchmark /usr/redis
# cp redis-cli  /usr/redis
# cp redis.conf  /usr/redis
# cd /usr/redis

3.启动服务

# redis-server   redis.conf
提示错误 -bash :redis-server:command not found

建立软连接
# ln -s /usr/redis/redis-server /usr/bin/redis-server
# ln -s /usr/redis/redis-cli /usr/bin/redis-cli
重新启动
# redis-server /usr/redis/redis.conf

启动成功

4.设置开机自启动

（1）先将redis.conf中daemonize设置为yes,确保守护进程开启。

（2）编写开机自启动脚本

# vi /etc/init.d/redis

PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/usr/redis/redis-server
REDIS_CLI=/usr/redis/redis-cli   

PIDFILE=/var/run/redis.pid
CONF="/usr/redis/redis.conf"
AUTH="1234"  

case "$1" in
        start)
                if [ -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is already running or crashed."
                else
                        echo "Starting Redis server..."
                        $EXEC $CONF
                fi
                if [ "$?"="0" ]
                then
                        echo "Redis is running..."
                fi
                ;;
        stop)
                if [ ! -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is not running."
                else
                        PID=$(cat $PIDFILE)
                        echo "Stopping..."
                       $REDIS_CLI -p $REDISPORT  SHUTDOWN
                        sleep 2
                       while [ -x $PIDFILE ]
                       do
                                echo "Waiting for Redis to shutdown..."
                               sleep 1
                        done
                        echo "Redis stopped"
                fi
                ;;
        restart|force-reload)
                ${0} stop
                ${0} start
                ;;
        *)
               echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
                exit 1
esac

注： redis设置AUTH命令

redis 127.0.0.1:6379> AUTH PASSWORD
(error) ERR Client sent AUTH, but no password is set
redis 127.0.0.1:6379> CONFIG SET requirepass "1234"
OK
redis 127.0.0.1:6379> AUTH 1234
Ok

（3）设置权限

# chmod 755 redis

（4）启动

# /etc/init.d/redis start  

提示错误 /etc/init.d/redis:permission denied

# chmod a+x /etc/init.d/redis
a+x 是给所有人加上可执行权限，包括所有者，所属组，和其他人
o+x 只是给其他人加上可执行权限

重新启动后显示
Starting Redis server... 
Redis is running ...

（5）设置开机自启动
# chkconfig redis on
提示错误 service redis does not support chkconfig

把下面两行注释放在/etc/init.d/redis文件靠前的注释中：

# chkconfig:   2345 90 10

# description:  Redis is a persistent key-value database

（6）关机重启测试
