 4.安装redis

中文官方网站:Http://www.redis.cn/
企业里面做Redis开发,99%都是Linux版的运用和安装。

第一步 下载redis

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

在这里插入图片描述

第二步 解压压缩包

tar -zxvf redis-4.0.6.tar.gz

[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz

第三步 yum安装gcc依赖

yum install gcc

[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc

遇到选择,输入y即可

第四步 跳转到redis解压目录下

cd redis-4.0.6

[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6

第五步 编译安装

make MALLOC=libc

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc

将/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录
cd src && make install

[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install
 CC Makefile.dep

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

 INSTALL install
 INSTALL install
 INSTALL install
 INSTALL install
 INSTALL install

5.启动redis

方式一 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

   `-._  _.-'           
    `-.__.-'            

18685:M 13 Dec 12:56:12.508 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
18685:M 13 Dec 12:56:12.508 # Server initialized
18685:M 13 Dec 12:56:12.508 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
18685:M 13 Dec 12:56:12.508 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. 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.
18685:M 13 Dec 12:56:12.508 * Ready to accept connections 

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。

方式二 以后台进程方式启动redis

第一步:修改redis.conf文件

daemonize no

修改为

daemonize yes

第二步:指定redis.conf文件启动

redis-server /usr/local/redis-4.0.6/redis.conf
ps -aux | grep redis查看redis进程

这样redis就在linux上安装成功了

6. redis的helloworld
