redis2.8安装

操作系统和redis安装包版本

CentOS Linux release 7.4.1708 (Core)

redis-2.8.19.tar.gz

操作系统配置

关闭大页

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.local

修改vm.overcommit_memory

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

修改somaconn

echo 511 > /proc/sys/net/core/somaxconn

安装需要的库

yum install -y epel-release
yum install jemalloc-devel
yum install gcc

epel的全称叫 Extra Packages for Enterprise Linux 。是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。装上了 EPEL之后，就相当于添加了一个第三方源，版本会比官方的包更新，而且还有一些官方没有的包，比如jemalloc-devel。

redis解压安装

tar -zxvf redis-2.8.19.tar.gz
cd redis-2.8.19

创建配置文件，目录并且做成service

配置文件模版

把配置文件放到/app 目录下redis.conf

pidfile "/app/redis/redis_6379.pid"
port 6379
logfile "/app/redis/redis.log"
daemonize yes
requirepass "xxxx"
databases 256
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave  0 0 0

tcp-backlog 511

maxclients 10000

dir "/app/redis"
save 900 1
save 300 10

dumpfile "dump.rdb"

appendonly yes
appendfilename "appendonly.aof"
appendfsync everysec

拷贝redis_init_script到/etc/init.d目录

cp ~/redis-2.8.19/utils/redis_init_script /etc/init.d/redis

修改redis_init_script文件里相关的配置PIDFILE和CONF

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

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

PIDFILE=/app/redis/redis_${REDISPORT}.pid
CONF="/app/redis/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
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
