新建redis用户
使用root用户登录虚机，添加用户并设置密码
#添加用户 [也可以通过-u -g -d参数指定特定的值来创建用户
[root@artisan ~]# useradd redis
#修改密码
[root@artisan ~]# passwd redis
Changing password for user redis.
New password:
BAD PASSWORD: it is too short
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfull
#查看
[redis@artisan ~]$ id redis
uid=501(redis) gid=501(redis) groups=501(redis)
安装Redis
切换到redis用户,创建目录,下载解压。我这台主机可以连外网，所以直接通过wget的方式下载，如果不能访问外网的话，可以下载后ftp到主机上。
[root@artisan ~]# su - redis
[redis@artisan ~]$ mkdir -p /home/redis/redis
[redis@artisan ~]$wget http://download.redis.io/releases/redis-4.0.11.tar.gz
[redis@artisan ~]$tar -xvzf redis-4.0.11.tar.gz
[redis@artisan ~]$cd redis-4.0.11
[redis@artisan ~]$make
make 错误一 未安装gcc
[redis@artisan redis-4.0.11]$ make
cd src && make all

make[1]: Leaving directory `/home/redis/redis/redis-4.0.11/src'

[redis@artisan redis-4.0.11]$
然后重新make
make 错误二 jemalloc
[redis@artisan redis-4.0.11]$ make

参考 https://unix.stackexchange.com/questions/94479/jemalloc-and-other-errors-making-redis-on-centos-6-4
执行上述命令后
[redis@artisan redis-4.0.11]$ make distclean

[redis@artisan redis-4.0.11]$ make

Hint: It's a good idea to run 'make test' ;)

[redis@artisan redis-4.0.11]$
整理文件
为了方便对Redis的配置和服进行管理，建立etc和bin目录
[redis@artisan redis-4.0.11]$ pwd
/home/redis/redis/redis-4.0.11
[redis@artisan redis-4.0.11]$ mkdir etc
[redis@artisan redis-4.0.11]$ mkdir bin
[redis@artisan redis-4.0.11]$ mv redis.conf etc/
[redis@artisan redis-4.0.11]$ cd src
[redis@artisan src]$ mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server redis-trib.rb ../bin
[redis@artisan src]$
启动redis
以默认的方式启动redis
可以直接使用./redis-server的方式 以默认形式启动redis.

后台方式启动redis
修改redis.conf 将 daemonize no 修改为 daemonize yes，保存重启redis.
[redis@artisan redis-4.0.11]$ cd bin/
[redis@artisan bin]$ ./redis-server ../etc/redis.conf
31864:C 19 Sep 21:11:01.500 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

- daemonize:yes:redis采用的是单进程多线程的模式。当redis.conf中选项daemonize设置成yes时，代表开启守护进程模式。在该模式下，redis会在后台运行，并将进程pid号写入至redis.conf选项pidfile设置的文件中，此时redis将一直运行，除非手动kill该进程。
- daemonize:no当daemonize选项设置成no时，当前界面将进入redis的命令行界面，exit强制退出或者关闭连接工具(putty,xshell等)都会导致redis进程退出。
后台启动方式下，启动之后打印了很少的的内容，查看是否启动成功，ps -ef|grep redis-server 命令即可。
访问redis
我这里使用了RedisDesktopManager 来连接访问redis server .
Redis版本redis-4.0.11
目前：
- 桥接模式，虚机的网络和宿主机（本地windows）网络一致，可ping通
- 虚拟机的防火墙已经关闭
- 虚拟机中的redis server 已经以后台方式启动，通过虚拟机上的redis-cli可操作
但是仍然访问不了 。
解决方法一 关闭保护模式
- Step1: redis.conf 将 bind 127.0.0.1 注释掉 https://bingozb.github.io/62.html
- Step2: redis.conf 关闭保护模式 (protected-mode no 3.2 之后加入的新特性）
- Step3: 重启redis
- Step4: 使用本地的RedisDesktopManager，可以正常访问。
经过验证，有效。
解决方法二 设置密码
Step1: redis.conf 将 bind 127.0.0.1 注释掉 https://bingozb.github.io/62.html
Step2: redis.conf 保持默认的保护模式开启状态，无需修改，使用修改配置文件或者命令行的方式来设置密
- 修改配置文件 redis.conf ，需要重启redis
- 命令行,无需重启redis
命令行方式设置密码，无需重启redis （临时密码，重启后失效）
[redis@artisan bin]$ ./redis-cli
127.0.0.1:6379> config set requirepass
(error) ERR Wrong number of arguments for CONFIG set

OK
127.0.0.1:6379> auth artisan

127.0.0.1:6379>
或者连接的使用通过 -a 指定密码连接
[redis@artisan bin]$ ./redis-cli
127.0.0.1:6379> set name artisan
(error) NOAUTH Authentication required.
127.0.0.1:6379> exit
[redis@artisan bin]$ ./redis-cli -a artisan
Warning: Using a password with '-a' option on the command line interface may not be safe.
127.0.0.1:6379>
127.0.0.1:6379> set name artisan

127.0.0.1:6379>
#查看当前密码
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "artisan"
客户端测试
修改redis.conf，需重启redis （永久设置）
Step1:在redis.conf 找到
# requirepass foobared
取消默认的注释，设置密码，比如：
requirepass artisan
建议设置一个很复杂的密码
Step2:指定配置文件，重新启动redis
[redis@artisan bin]$ pkill redis-server
[redis@artisan bin]$ ./redis-server ../etc/redis.conf
32394:C 19 Sep 23:33:17.462 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

Java 中操作带有密码的redis
操作之前先 清空redis
我们直接在虚机上的客户端操作下
[redis@artisan bin]$ ./redis-cli
127.0.0.1:6379> auth artisan
OK
127.0.0.1:6379> flushdb
OK
127.0.0.1:6379> keys *
(empty list or set)
127.0.0.1:6379>
主要是 jedis.auth(“artisan”);
package com.artisan.redis.withjava;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
public class JavaRedisInsertWithJedisPool {
public static void main(String[] args) {
// 实例化jedisPoolConfig并设置相关参数
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxIdle(50);
jedisPoolConfig.setMaxTotal(100);
jedisPoolConfig.setMaxWaitMillis(2000);
// 使用jedisPoolConfig初始化redis的连接池
JedisPool jedisPool = new JedisPool(jedisPoolConfig, "192.168.31.66", 6379);
// 从jedisPool中获取一个连接
Jedis jedis = jedisPool.getResource();
jedis.auth("artisan");
int i = 0 ;
long beginTime = System.currentTimeMillis();
try {
while (true) {
long endTime = System.currentTimeMillis();
// 超过一秒 停止操作
if (endTime - beginTime > 1000) {
break;
}
i++;
// 写入redis
jedis.set("artisan-" + i, String.valueOf(i));
}
} catch (Exception e) {
e.printStackTrace();
} finally {
// 关闭redis
jedis.close();
}
System.out.println("1S内对redis的写入次数为" + i);
}
}
输出
