Redis

环境

Centos 7
redis-5.0.4

开始安装

安装的过程中可以直接使用 yum ，但是这样安装的Redis版本比较低

[root@izwz9ga6l7ls6ozy9ylwbdz wsk]# yum install redis
.....
Installed:redis.x86_64 0:3.2.12-2.el7
Complete!

当我们需要高版本的时候，可以使用 wget 命令

1. 下载redis安装包

[root@izwz9ga6l7ls6ozy9ylwbdz redis]# wget http://download.redis.io/releases/redis-5.0.4.tar.gz

2. 解压压缩包

[root@izwz9ga6l7ls6ozy9ylwbdz redis]# tar zxvf redis-5.0.4.tar.gz

3. 编译安装

先编译库

[root@izwz9ga6l7ls6ozy9ylwbdz redis-5.0.4]# make MALLOC=libc

再编译资源

[root@izwz9ga6l7ls6ozy9ylwbdz redis-5.0.4]# cd src && make installCC Makefile.depHint: It's a good idea to run 'make test' ;)INSTALL installINSTALL installINSTALL installINSTALL installINSTALL install

至此，就算安装完成了。

启动Redis

有多种方法可以启动

1. ./redis-server

在目录 src 下执行

[root@izwz9ga6l7ls6ozy9ylwbdz src]# ./redis-server

但是这样执行的 Redis 是前台任务，会随着终端的退出而关闭。
如果想要后台一直运行，可以这样

[root@izwz9ga6l7ls6ozy9ylwbdz src]# nohup ./redis-server &
[1] 20876

redis-server

直接启动 Redis 服务

[root@izwz9ga6l7ls6ozy9ylwbdz src]# redis-server

同理，但是这样执行的 Redis 是前台任务，会随着终端的退出而关闭。
如果想要后台一直运行，可以这样

[root@izwz9ga6l7ls6ozy9ylwbdz src]# nohup redis-server &
[1] 20948

查看Redis服务

先输入 redis-cli ，接下来可以 ping 一下

[root@izwz9ga6l7ls6ozy9ylwbdz redis]# redis-cli
127.0.0.1:6379> ping
PONG

设置一个 string 看看效果。

127.0.0.1:6379> set wsk 1103
OK
127.0.0.1:6379> get wsk
"1103"

退出redis-cli

127.0.0.1:6379> quit

设置开机自动启动

一般作为一个Redis服务器，当开机的时候，需要自动启动Redis。将Redis服务作为守护线程(daemon)。

修改 redis.conf 配置文件，修改为守护线程模式。

在 redis-5.0.4 目录下，编辑redis.conf

[root@izwz9ga6l7ls6ozy9ylwbdz redis-5.0.4]# vi redis.conf

搜索 daemonize
默认情况下为 daemonize no ，修改为 daemonize yes

复制一份 redis.conf 到 /etc/redis/ 下，并重命名为 6379.conf

[root@izwz9ga6l7ls6ozy9ylwbdz redis-5.0.4]# mkdir /etc/redis
[root@izwz9ga6l7ls6ozy9ylwbdz redis-5.0.4]# cp redis.conf /etc/redis/6379.conf

复制一份 utils/redis_init_script 到 /etc/init.d/

[root@izwz9ga6l7ls6ozy9ylwbdz utils]# cp /home/wsk/redis/redis-5.0.4/utils/redis_init_script /etc/init.d/

先测试启动一下：

[root@izwz9ga6l7ls6ozy9ylwbdz utils]# cd /etc/init.d/
[root@izwz9ga6l7ls6ozy9ylwbdz init.d]# ./redis_init_script start
Starting Redis server...
2317:C 29 Mar 2019 13:37:58.739 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
2317:C 29 Mar 2019 13:37:58.739 # Redis version=5.0.4, bits=64, commit=00000000, modified=0, pid=2317, just started
2317:C 29 Mar 2019 13:37:58.739 # Configuration loaded

设置开启启动

[root@izwz9ga6l7ls6ozy9ylwbdz init.d]# chkconfig redis_init_script on

当要取消的时候，把 on 修改为 off

重启服务器

[root@izwz9ga6l7ls6ozy9ylwbdz init.d]# reboot

重启后测试

[root@izwz9ga6l7ls6ozy9ylwbdz ~]# redis-cli

卸载Redis

先关闭进程

查询进程，根据 PID 关闭

[root@izwz9ga6l7ls6ozy9ylwbdz ~]# ps -ef | grep redis
root       821     1  0 13:39 ?        00:00:00 /usr/local/bin/redis-server 127.0.0.1:6379
root      2360  2273  0 13:51 pts/0    00:00:00 grep --color=auto redis
[root@izwz9ga6l7ls6ozy9ylwbdz ~]# kill -9 821

查找 Redis 相关文件

[root@izwz9ga6l7ls6ozy9ylwbdz ~]# find / -name redis*
