linux安装redis

1、安装

虽然之前已经装过了  再记录一下

去官网下载最新稳定版 http://redis.io/download 

[root@centos7 bin]# wget http://download.redis.io/releases/redis-5.0.4.tar.gz

解压 

[root@centos7 bin]# tar -zxvf redis-5.0.4.tar.gz

进入解压的文件夹    cd

[root@centos7 bin]# cd redis-5.0.4

编译 

[root@centos7 bin]# make

安装 make install PREFIX=/usr/local/redis

[root@centos7 redis-5.0.4]# make install PREFIX=/usr/local/redis
cd src && make install
make[1]: 进入目录“/usr/src/redis-5.0.4/src”
    CC Makefile.dep
make[1]: 离开目录“/usr/src/redis-5.0.4/src”
make[1]: 进入目录“/usr/src/redis-5.0.4/src”

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

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[1]: 离开目录“/usr/src/redis-5.0.4/src”

测试 进入目录启动redis

[root@centos7 redis]# cd /usr/local/redis/bin/
[root@centos7 bin]# ./redis-server

11113:M 16 Apr 2019 12:20:33.057 # 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.

 启动成功。

退出：Ctrl+c 即可退出。

2、配置

后台启动redis

复制解压文件夹里redis的配置文件到安装的bin目录

[root@centos7 bin]# cp /usr/src/redis-5.0.4/redis.conf /usr/local/redis/bin/

修改配置文件

[root@centos7 bin]# vim redis.conf 

找到 daemonize=no  修改为yes，保护守护进程开启，也就是在后台可以运行

在第136行

 

保存退出

[root@centos7 bin]# ./redis-server redis.conf
11153:C 16 Apr 2019 12:29:38.761 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
11153:C 16 Apr 2019 12:29:38.762 # Redis version=5.0.4, bits=64, commit=00000000, modified=0, pid=11153, just started
11153:C 16 Apr 2019 12:29:38.762 # Configuration loaded
 

这样就可以后台启动了

输入命令查看是否后台启动了

[root@centos7 bin]# ps aux|grep redis
root      11154  0.1  0.4 153884  7672 ?        Ssl  12:29   0:00 ./redis-server 127.0.0.1:6379
root      11159  0.0  0.0 112724   984 pts/0    S+   12:30   0:00 grep --color=auto redis

结束进程

[root@centos7 bin]# kill 11154     

也可以强制结束

[root@centos7 bin]# kill -9  11154

设置开机自启动redis

[root@centos7 bin]# systemctl enable redis
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.

重启开机之后输入命令  redis已经启动了

 

[root@centos7 ~]# systemctl status redis

   Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)

 测试启动redis客户端 成功

[root@centos7 ~]# /usr/local/redis/bin/redis-cli
