Centos 下编译安装Redis

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.

    *)
      echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
          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
