安装环境说明：

操作系统：Centos 6.5 -64bit

安装路径：/usr/local/redis

开始编译redis

tar -zxvf redis-2.8.19.tar.gz

cd redis-2.8.19

make

make PREFIX=/usr/local/redis install

Redis配置

mkdir /usr/local/redis/etc/

cp redis.conf /usr/local/redis/etc/

cd /usr/local/redis/bin/

cp redis-benchmark redis-cli redis-server /usr/bin/

调整下内存分配使用方式并使其生效

#此参数可用的值为0,1,2

#0表示当用户空间请求更多的内存时，内核尝试估算出可用的内存

#1表示内核允许超量使用内存直到内存用完为止

#2表示整个内存地址空间不能超过swap+(vm.overcommit_ratio)%的RAM值

echo "vm.overcommit_memory=1">>/etc/sysctl.conf

sysctl -p

修改redis配置

vim /usr/local/redis/etc/redis.conf

# 修改一下配置

# redis以守护进程的方式运行

# no表示不以守护进程的方式运行(会占用一个终端)

daemonize yes

# 客户端闲置多长时间后断开连接，默认为0关闭此功能

timeout 300

# 设置redis日志级别，默认级别：notice

loglevel verbose

# 设置日志文件的输出方式,如果以守护进程的方式运行redis 默认:""

# 并且日志输出设置为stdout,那么日志信息就输出到/dev/null里面去了

logfile stdout

redis环境变量配置

vim /etc/profile

export PATH="$PATH:/usr/local/php/bin:/usr/local/mysql/bin:/usr/local/redis/bin"

# 保存退出

# 让环境变量立即生效

source /etc/profile

Redis 启动脚本

  #!/bin/bash

  #chkconfig: 2345 80 90

  # Simple Redis init.d script conceived to work on Linux systems

  # as it does use of the /proc filesystem.

  PATH=/usr/local/bin:/sbin:/usr/bin:/bin

          exit 1

  esac

Redis 启动、停止测试

service redis start   #或者 /etc/init.d/redis start

service redis stop   #或者 /etc/init.d/redis stop

# 查看redis进程

ps -el|grep redis

# 端口查看

netstat -an|grep 3306

Redis 防火墙配置

打开防火墙规则

vim /etc/sysconfig/iptables

# 增加内容

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT

# 重启火墙规则立即生效

service iptables restart
