Redis 环境安装

Redis 环境安装

安装

如果已经安装了老版本3.0.6

1. 卸载软件
sudo apt-get remove redis-server
2. 清除配置
sudo apt-get remove --purge redis-server
3. 删除残留文件
sudo find / -name redis
一般设置如下
sudo rm -rf var/lib/redis/
sudo rm -rf /var/log/redis
sudo rm -rf /etc/redis/
sudo rm -rf /usr/bin/redis-*
sudo rm -rf /usr/local/bin/redis-*
sudo rm -rf /usr/local/redis/

下载地址：http://redis.io/download，下载最新文档版本，稳定版系列.

下载安装文件
wget http://download.redis.io/releases/redis-3.2.3.tar.gz

解压
tar -zxvf redis-3.2.3.tar.gz

copy文件并ls查看
sudo mkdir -p /usr/local/redis/
sudo cp -r redis-3.2.3/* /usr/local/redis/
ls /usr/local/redis/

进入安装目录
cd /usr/local/redis/

编译

首先打开README.md，翻阅基本build和install方式。

vi README.md
sudo make

尝试环境是否可以正常使用(Hint: It's a good idea to run 'make test' ;)

sudo make test

如果出现

\o/ All tests passed without errors!

表示redis环境没有问题。

安装最后安装路径

cd src
sudo make install

查看编译好的命令文件

ls /usr/local/bin/redis-*
—/usr/local/bin/redis-benchmark 性能测试工具,例如：redis-benchmark -n 1000000 -c 50 , 50个客户端，并发1000000个SETs/GETs查询
—/usr/local/bin/redis-check-aof 更新日志检查
—/usr/local/bin/redis-check-dump 本地数据文件检查
—/usr/local/bin/redis-cli 命令行操作工具
—/usr/local/bin/redis-server 服务器程序

修改配置文件

cd ..
sudo mkdir /etc/redis
sudo cp redis.conf /etc/redis/
ls /etc/redis/redis.conf

启动redis

python@ubuntu:~$sudo redis-server /etc/redis/redis.conf

出现以下代表启动成功

python@ubuntu:~$ redis-sever /etc/redis/redis.conf
未找到 'redis-sever' 命令，您要输入的是否是：
命令 'redis-server' 来自于包 'redis-server' (universe)
redis-sever：未找到命令
python@ubuntu:~$ redis-server /etc/redis/redis.conf

23003:M 17 Sep 10:52:57.537 # 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.
23003:M 17 Sep 10:52:57.537 # 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.
