# 安装 #

[redis下载官网][redis]  
1.下载解压包

wget http://download.redis.io/releases/redis-5.0.5.tar.gz

2.解压包

tar xzf redis-5.0.5.tar.gz

3.进入解压文件目录

cd redis-5.0.5

4.编译

make

**出现问题**  
![在这里插入图片描述][20190723093439692.png]  
说明未安装gcc，使用命令安装gcc

yum install gcc

**gcc安装完后make又出现了下面问题**  
![在这里插入图片描述][20190723093906853.png]  
原因是jemalloc重载了Linux下的ANSI C的malloc和free函数。解决办法：make时添加参数。

make MALLOC=libc

完成后进行，执行这个的目的就是将可执行文件拷贝到/usr/local/bin/目录下，这样就可以直接执行redis-server 、redis-cli 等命令了。

make install

5.查看版本

[root@VM_0_16_centos bin]# redis-server -v
    Redis server v=5.0.5 sha=00000000:0 malloc=libc bits=64 build=57ca631c3a0a9413

6.启动服务

[root@VM_0_16_centos bin]# redis-server 
    21136:C 23 Jul 2019 09:47:39.312 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
    21136:C 23 Jul 2019 09:47:39.312 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=21136, just started
    21136:C 23 Jul 2019 09:47:39.312 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
                    _._

To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
    21136:M 23 Jul 2019 09:47:39.314 * Ready to accept connections

7.重新打开终端，插入数据进行测试

[root@VM_0_16_centos ~]# redis-cli
    127.0.0.1:6379> set name zhangsan
    OK
    127.0.0.1:6379> get name
    "zhangsan"
    127.0.0.1:6379> keys *
    1) "name"
    127.0.0.1:6379>

8.设置后台运行

[root@VM_0_16_centos redis]# mkdir /etc/redis
    [root@VM_0_16_centos redis]# cp redis.conf /etc/redis
    [root@VM_0_16_centos redis]# vim /etc/redis/redis.conf

找到"daemonize no" no改为yes你可以在命令行模式下输入/进行查找

![在这里插入图片描述][20190723095745466.png]  
指定配置文件后台启动redis

[root@VM_0_16_centos redis]# redis-server /etc/redis/redis.conf 
    22528:C 23 Jul 2019 10:00:13.732 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
    22528:C 23 Jul 2019 10:00:13.732 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=22528, just started
    22528:C 23 Jul 2019 10:00:13.732 # Configuration loaded

9.redis开机启动  
拷贝 redis 安装目前下的 /root/redis-5.0.5/utils/redis\_init\_script 到 /etc/init.d/redis文件中；

cp /root/redis-5.0.5/utils/redis_init_script /etc/init.d/redis

编辑/etc/init.d/redis文件

[root@VM_0_16_centos init.d]# vim redis 
    	CONF="/etc/redis/redis.conf"(这路径是第八步的复制后的路径)
    [root@VM_0_16_centos init.d]# chkconfig --add redis（这一步好像不用也可以）
    [root@VM_0_16_centos init.d]# chkconfig redis on 
    [root@VM_0_16_centos init.d]# service redis stop
    Stopping ...
    Redis stopped
    [root@VM_0_16_centos init.d]# service redis start
    Starting Redis server...

停止，开启

/etc/init.d/redis stop
    /etc/init.d/redis start

10.连接RedisDesktopManager

[root@VM_0_16_centos ~]# vim /etc/redis/redis.conf

编辑Redis的配置文件，我这里是第八步自己创建的文件

记得重启redis
