1、安装redis

redis 目前没有官方 RPM 安装包，我们需要从源代码编译，而为了要编译就需要安装 Make 和 GCC。

如果没有安装过 GCC 和 Make，那么就使用 yum 安装 -------yum install gcc make

第一步：下载redis安装包

wget http://download.redis.io/releases/redis-4.0.6.tar.gz

[root@iZwz991stxdwj560bfmadtZ local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz

第二步：解压压缩包

tar -zxvf redis-4.0.6.tar.gz

第四步：跳转到redis解压目录下

cd redis-4.0.6

第五步：使用Make 编译源文件-----------------make　

第六步：测试是否安装成功

先切换到redis src目录下

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src

1、直接启动redis

./redis-server

[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server
18685:C 13 Dec 12:56:12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started
18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

Redis must be restarted after THP is disabled.

如上图：redis启动成功，但是这种启动方式需要一直打开窗口，不能进行其他操作，不太方便。

按 ctrl + c可以关闭窗口。

2、以后台进程方式启动redis

第一步：修改redis.conf文件

将

daemonize no　　

修改为

daemonize yes

第二步：指定redis.conf文件启动

./redis-server /opt/redis/redis-4.0.6/redis.conf

[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /opt/redis/redis-4.0.6/redis.conf
C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started
C 13 Dec 13:07:41.109 # Configuration loaded

第三步：关闭redis进程

首先使用ps -aux | grep redis查看redis进程

[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis
root     18714  0.0  0.1 141752  2008 ?        Ssl  13:07   0:00 ./redis-server 127.0.0.1:6379
root     18719  0.0  0.0 112644   968 pts/0    R+   13:09   0:00 grep --color=auto redis

使用kill命令杀死进程

[root@iZwz991stxdwj560bfmadtZ src]# kill -9 18714

第七步：设置redis开机自启动

mkdir redis

[root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis

2、将/opt/redis/redis-4.0.6/redis.conf 文件复制一份到/etc/redis目录下，并命名为6379.conf　　

[root@iZwz991stxdwj560bfmadtZ redis]# cp /opt/redis/redis-4.0.6/redis.conf /etc/redis/6379.conf

3、将redis的启动脚本复制一份放到/etc/init.d目录下

[root@iZwz991stxdwj560bfmadtZ init.d]# cp /opt/redis/redis-4.0.6/utils/redis_init_script /etc/init.d/redis_init_script

4、设置redis开机自启动

先切换到/etc/init.d目录下

然后执行自启命令

[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redis_init_script on
service redisd does not support chkconfig　

看结果是redis_init_script不支持chkconfig

解决方法：

使用vim编辑redis_init_script文件，在第三行加入如下两行注释，保存退出

# chkconfig:   2345 90 10
# description:  Redis is a persistent key-value database

注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。

同时还要修改参数,指定redis的安装路径

修改完成后按 Esc ,再按 :wq + Enter(回车) 保存并退出

修改完成后的截图

再次执行开机自启命令，成功

[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redis_init_script on

现在可以直接已服务的形式启动和关闭redis了

启动：

service redis_init_script start　　

[root@izwz991stxdwj560bfmadtz ~]# service redis_init_script start
Starting Redis server...
2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started
2288:C 13 Dec 13:51:38.087 # Configuration loaded

关闭：

service redis_init_script stop

[root@izwz991stxdwj560bfmadtz ~]# service redis_init_script stop
Stopping ...
Redis stopped

如果出现如下问题：

[root@iZwz991stxdwj560bfmadtZ ~]# service redis_init_script start
/var/run/redis_6379.pid exists, process is already running or crashed

简单的java连接Redis并使用测试
