centos 6.5 安装配置redis

Posted 2020-08-22

基于CentOS release 6.5 Final， redis版本3.0.2 [redis版本号中间位是偶数的是稳定版，奇数的为非稳定版]

一、安装redis

1)     下载redis安装包

可去官网http://redis.io ，也可通过wget命令，

[[email protected] srv]# wget http://download.redis.io/redis-stable.tar.gz 

2）解压

[[email protected] srv]# tar -zxvf redis-stable.tar.gz 

3）编译、安装（编译安装安装Development tools和Desktop Platfrom 开发包组工具）

[[email protected] srv]# cd redis-stable

[[email protected] redis-stable]# ll

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

[[email protected] redis-stable]# make install

cd src && make install

make[1]: Entering directory `/srv/redis-stable/src‘

[[email protected] redis-stable]# 

[[email protected] redis-stable]# ls /usr/local/bin

redis-benchmark  redis-check-aof  redis-check-rdb  redis-cli  redis-sentinel  redis-server

[[email protected] redis-stable]# 

[[email protected] redis-stable]# /usr/local/bin/redis-server -v

Redis server v=3.2.5 sha=00000000:0 malloc=jemalloc-4.0.3 bits=64 build=661b15c1ebfa36b

注意：若此时执行redis-server –v (查看版本命令)，若提示redis-server command not found，则需要将/usr/local/bin目录加到环境变量，如何添加，此处不做详细介绍，可查看修改/etc/profile，(查看环境变量命令：echo $PATH)

至此，redis安装完成，接着配置。

二、修改配置文件.conf

1)创建配置文件目录，dump file目录，进程目录，log目录等

配置文件一般放在/etc/下，创建fedis目录

[[email protected] redis-stable]# cd /etc/

[[email protected] etc]# mkdir redis

dump file、进程目录、log目录等，一般放在/var/目录下，

[[email protected] etc]# cd redis/

[[email protected] redis]# ls

[[email protected] redis]# cd /var

[[email protected] var]# mkdir redis

[[email protected] var]# cd redis/

[[email protected] redis]# mkdir data log run

[[email protected] redis]# ll

total 12

drwxr-xr-x. 2 root root 4096 Dec  5 15:58 data

drwxr-xr-x. 2 root root 4096 Dec  5 15:58 log

drwxr-xr-x. 2 root root 4096 Dec  5 15:58 run

[[email protected] redis]# 

至此目录创建完毕。

2）修改配置文件，配置参数

首先拷贝解压包下的redis.conf文件至/etc/redis

[[email protected] redis-stable]# cp redis.conf /etc/re

readahead.conf    redhat-lsb/       redhat-release    redis/            resolv.conf       resolv.conf.save

[[email protected] redis-stable]# cp redis.conf /etc/redis/

[[email protected] redis-stable]# vi /etc/redis/redis.conf  最好备份一份redis.conf.bak

# Accept connections on the specified port, default is 6379 (IANA #815344).

# If port 0 is specified Redis will not listen on a TCP socket.

port 6379   

#####修改默认端口

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

# nothing bad happens, the server will start and run normally.

pidfile /var/run/redis_6379.pid

#####修改pid目录为新建的目录

# The working directory.

#

# The DB will be written inside this directory, with the filename specified

# above using the ‘dbfilename‘ configuration directive.

#

# The Append Only File will also be created inside this directory.

#

# Note that you must specify a directory here, not a file name.

dir ./

#####修改dump目录为新建目录

# Specify the log file name. Also the empty string can be used to force

# Redis to log on the standard output. Note that if you use standard

# output for logging but daemonize, logs will be sent to /dev/null

logfile ""

#####修改log存储目录为新建目录

3）持久化
默认rdb，可选择是否开启aof，若开启，修改配置文件appendonly

4)启动redis,查看各目录下文件

[[email protected] redis-stable]# redis-server /etc/redis/redis.conf 

查看dump，log，pid等

[[email protected] redis]# cd data

[[email protected] data]# ll

total 0

[[email protected] data]# ll../log

-bash: ll../log: No such file or directory

[[email protected] data]# ll ../log

total 4

-rw-r--r--. 1 root root 1861 Dec  5 16:15 redis.log

[[email protected] data]# ll ../run

total 4

-rw-r--r--. 1 root root 6 Dec  5 16:15 redis_6379.pid

[[email protected] data]# 

发现只有日志，没有dump和pid信息，是因为当前redis服务仍然是console模式运行的，且没有数据存储操作

停止redis服务，修改配置文件使得redis在background运行

改成yes，保存，重启redis服务

5）客户端连接redis

[[email protected] run]# redis-cli

127.0.0.1:6379>    #####默认端口6379

6）至此，redis基础配置完毕，若有其他相关配置调整，可查找文档在修改
三、服务及开机自启动

 1）创建redis启动脚本

拷贝解压包下utils下redis启动脚本至/etc/init.d

[[email protected] redis-stable]# cd /srv/redis-stable/utils/

[[email protected] utils]# cp redis_init_script /etc/init.d/

修改脚本名称为redis 并修改脚本pid及conf路径为实际路径

至此，在/etc/init.d目录下，已经可以通过service redis start/stop 启动/关闭redis服务了。

2、给启动脚本添加删除权限

#chmod +x /etc/init.d/redis  给启动脚本添加权限

#chmod -x /etc/init.d/redis  删除权限

3、设置自启动

#chkconfig redis on

如果运行报错，提示

[[email protected] init.d]# chkconfig redis on

service redis does not support chkconfig

是因为没有在启动脚本里加入redis启动优先级信息，可添加如下

再次执行chkconfig redis on,成功，至此自启动配置完毕。
