Linux环境下redis安装与配置

1、 下载redis

下载地址：http://redis.io/

根据需要选择合适的redis版本和符合系统配置的包。

这边以redis-3.2.3.tar.gz 为例，（以上传到云盘上地址如下：http://pan.baidu.com/s/1hs0mIQK）先将redis包通过FTP工具（如：FileZilla等）上传到Linux服务器上（目录为：/usr/local/soft）

2、 安装redis

[root@iZ23l73bebkZ ~]# cd /usr/local/soft/

[root@iZ23l73bebkZ soft]# ll

total 1508

-rw-r--r-- 1 root root 1541401 Sep 22 11:39 redis-3.2.3.tar.gz

[root@iZ23l73bebkZ soft]# tar -zxvf redis-3.2.3.tar.gz

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

make[1]: Leaving directory `/usr/local/soft/redis-3.2.3/src'

cd src && make install

make[1]: Entering directory `/usr/local/soft/redis-3.2.3/src'

3、调整内存

/etc/sysctl.conf

添加

vm.overcommit_memory=1

刷新配置使之生效

sysctl vm.overcommit_memory=1

如果内存情况比较紧张的话，需要设定内核参数：

echo 1 > /proc/sys/vm/overcommit_memory

这里说一下这个配置的含义：

/proc/sys/vm/overcommit_memory
该文件指定了内核针对内存分配的策略，其值可以是0、1、2。
0，表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存，内存申请允许；否则，内存申请失败，并把错误返回给应用进程。
1，表示内核允许分配所有的物理内存，而不管当前的内存状态如何。
2，表示内核允许分配超过所有物理内存和交换空间总和的内存
设置可选部分：拷贝文件

cp redis.conf /etc/ #这个文件时redis启动的配置文件

cp redis-benchmark redis-cli redis-server /usr/bin/ #这个倒是很有用，这样就不用再执行时加上./了，而且可以在任何地方执行

[root@iZ23l73bebkZ redis-3.2.3]# cp redis.conf /etc/

[root@iZ23l73bebkZ redis-3.2.3]# cd src/

[root@iZ23l73bebkZ src]# ll

[root@iZ23l73bebkZ src]# cp redis-benchmark redis-cli redis-server /usr/bin/

3、 编辑redis.conf

daemonize yes #转为守护进程，否则启动时会每隔5秒输出一行监控信息

save 60 1000 #减小改变次数，其实这个可以根据情况进行指定

maxmemory 1024000000 #分配256M内存

[root@iZ23l73bebkZ redis-3.2.3]# vim redis.conf

################################# GENERAL #####################################

# By default Redis does not run as a daemon. Use 'yes' if you need it.

# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.

daemonize yes

# If you run Redis from upstart or systemd, Redis can interact with your

# supervision tree. Options:

# supervised no - no supervision interaction

# supervised upstart - signal upstart by putting Redis into SIGSTOP mode

# supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET

# supervised auto - detect upstart or systemd method based on

# UPSTART_JOB or NOTIFY_SOCKET environment variables

# Note: these supervision methods only signal "process is ready."

# They do not enable continuous liveness pings back to your supervisor.

supervised no

# If a pid file is specified, Redis writes it where specified at startup

# and removes it at exit.

#

# When the server runs non daemonized, no pid file is created if none is

# specified in the configuration. When the server is daemonized, the pid file

# is used even if not specified, defaulting to "/var/run/redis.pid".

#

# Creating a pid file is best effort: if Redis is not able to create it

5、服务管理
5.1 启动服务

redis-server redis.conf #启动服务

5.2 存储值

redis-cli set name zhoufeng redis-cli get name

5.3 关闭服务

redis-cli shutdown

5.3.1 如果端口变化可以指定端口:

redis-cli -p 6380 shutdown
