Centos 下编译安装Redis

安装环境说明：

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

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/

#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

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
REDISPORT=6379
EXEC=/usr/local/redis/bin/redis-server
REDIS_CLI=/usr/local/redis/bin/redis-cli

PIDFILE=/var/run/redis.pid
CONF="/usr/local/redis/etc/redis.conf"

case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed"
else
echo "Starting Redis server..."
$EXEC $CONF
fi
if [ "$?"="0" ]
then
echo "Redis is running..."
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$REDIS_CLI -p $REDISPORT SHUTDOWN
while [ -x ${PIDFILE} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
fi
;;
restart|force-reload)
${0} stop
${0} start
;;
*)
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
