redis安装配置-开启密码验证
redis安装
1) 下载redis最新稳定版本官网地址：https://redis.io/，我下载的是http://download.redis.io/releases/redis-3.2.8.tar.gz
2) 将redis-3.2.8.tar.gz上传至Linux（CentOs6.5 64位）的/home目录下；
3) 解压redis-3.2.8.tar.gz
1 tar -xvf redis-3.2.8.tar.gz 2 cd redis-3.2.8 3 make PREFIX=/usr/local/redis install #安装到指定目录/usr/local/redis
4) 复制脚本redis_init_script 到/etc/rc.d/init.d目录下，并改名为redis
1 cp /home/redis-3.2.8/utils/redis_init_script /etc/rc.d/init.d/redis
5) 修改/etc/rc.d/init.d/redis，修改后的内容如下：
1 #!/bin/sh 2 #chkconfig:2345 80 90 #新增 3 # Simple Redis init.d script conceived to work on Linux systems 4 # as it does use of the /proc filesystem. 5 6 REDISPORT=6379 7 EXEC=/usr/local/redis/bin/redis-server 8 CLIEXEC=/usr/local/redis/bin/redis-cli #/usr/local/redis/bin为redis实际安装目录 9 10 PIDFILE=/var/run/redis_${REDISPORT}.pid 11 CONF="/etc/redis/${REDISPORT}.conf" 12 13 case "$1" in 14 start) 15 if [ -f $PIDFILE ] 16 then 17 echo "$PIDFILE exists, process is already running or crashed" 18 else 19 echo "Starting Redis server..." 20 $EXEC $CONF & #启动后在后台运行redis 21 fi 22 ;; 23 stop) 24 if [ ! -f $PIDFILE ] 25 then 26 echo "$PIDFILE does not exist, process is not running" 27 else 28 PID=$(cat $PIDFILE) 29 echo "Stopping ..." 30 $CLIEXEC -p $REDISPORT shutdown 31 while [ -x /proc/${PID} ] 32 do 33 echo "Waiting for Redis to shutdown ..." 34 sleep 1 35 done 36 echo "Redis stopped" 37 fi 38 ;; 39 *) 40 echo "Please use start or stop as first argument" 41 ;; 42 esac
6) 拷贝配置文件
/etc/rc.d/init.d/redis配置文件中指定了CONF="/etc/redis/${REDISPORT}.conf";所以我们要创建/etc/redis文件夹，把redis的配置文件拷贝进来，并且命名为6379.conf
cp /home/redis-3.2.8/redis.conf /etc/redis/6379.conf
7) 开启密码验证（如果不需要开启，可以略过）
vi /etc/redis/6379.conf #找到requirepass foobare去掉前面的#号，foobare为密码，可以改为自己需要的，我改成了myredis
8) 增加为服务
chkconfig -add redis
9）启动redis服务
service redis start
10）登录redis
密码登录方式：①在客户端登录时给出密码 ②在客户端登录时不给密码，开始执行命令时给出密码。如下：
方式① [root@huarui bin]# ./redis-cli -a myredis 127.0.0.1:6379> keys * (empty list or set) 127.0.0.1:6379> 方式② [root@huarui bin]# ./redis-cli 127.0.0.1:6379> keys * (error) NOAUTH Authentication required. #没给出密码时执行keys * 报错 127.0.0.1:6379> auth myredis #给出密码 OK 127.0.0.1:6379> keys * #再次执行keys * ,OK! (empty list or set) 127.0.0.1:6379>
11)关闭redis服务
因为开启了密码验证，不能使用service redis stop方式停止，会报错。如下：
1 [root@huarui bin]# service redis stop 2 Stopping ... 3 (error) NOAUTH Authentication required. 4 Waiting for Redis to shutdown ... 5 Waiting for Redis to shutdown ...
解决：登录redis执行shutdown命令
停止前： [root@huarui bin]# ps -ef|grep redis root 2472 1 0 14:47 pts/0 00:00:00 /usr/local/redis/bin/redis-server 127.0.0.1:6379 root 2476 2371 0 14:47 pts/0 00:00:00 grep redis 开始停止操作： [root@huarui bin]# ./redis-cli 127.0.0.1:6379> auth myredis OK 127.0.0.1:6379> shutdown 2472:M 11 Apr 14:51:40.207 # User requested shutdown... 2472:M 11 Apr 14:51:40.207 * Saving the final RDB snapshot before exiting. 2472:M 11 Apr 14:51:40.240 * DB saved on disk 2472:M 11 Apr 14:51:40.240 * Removing the pid file. 2472:M 11 Apr 14:51:40.240 # Redis is now ready to exit, bye bye... not connected> 停止后： [root@huarui bin]# ps -ef|grep redis root 2536 2371 0 14:52 pts/0 00:00:00 grep redis 已经没有了redis进程
12)redis环境变量配置
修改profile文件：
#vi /etc/profile
在最后行添加
export PATH="$PATH:/usr/local/redis/bin"
