redis(二)redis+TCMALLOC高性能的缓存服务器的安装配置

安装 

1准备编译环境 

  yum -y install gcc gcc+ gcc-c++ openssl openssl-devel pcre pcre-devel 

2 下载源码包(由于google不能上所以选择从本地上传) 

wget 172.60.0.172:8080/libunwind-1.1.tar.gz 

wget 172.60.0.172:8080/gperftools-2.1.tar.gz 

wget 172.60.0.172:8080/redis-2.8.10.tar.gz 

3 编译安装 

依次安装 

tar xf  libunwind-1.1.tar.gz 

CFLAGS=-fPIC ./configure 

make CFLAGS=-fPIC 

make CFLAGS=-fPIC install 



gperftools的安装主要是用到了TCMALLOC来提高性能所以最简化安装 

tar xf gperftools-2.1.tar.gz 

cd gperftools-2.1 

./configure  --disable-cpu-profiler --disable-heap-profiler --disable-heap-checker --disable-debugalloc --enable-minimal 

make && make install 

echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf 

/sbin/ldconfig 

cd /usr/local/lib 

ln -sv libtcmalloc_minimal.so.4.1.2 libtcmalloc.so 





redis的安装 

tar xf redis-2.8.10.tar.gz 

cd redis2.8.10 

mkdir –p /opt/redis 

make PREFIX=/opt/redis USE_TCMALLOC=yes FORCE_LIBC_MALLOC=yes install 

三 配置 

创建配置文件夹以及文件 

 mkdir -p /opt/redis/etc 

mkdir -p /opt/redis/run 

mkdir -p /opt/redis/data/6379 

mkdir -p /opt/redis/log 

cp /redis的解压路径 /redis.conf /opt/redis/etc/redis.conf 

cp /opt/redis/etc/redis.conf /opt/redis/etc/redis_6379.conf 

修改配置文件： 

vim /opt/redis/etc/redis_6379.conf 

daemonize yes 

pidfile /opt/redis/run/redis_6379.pid 

dir /opt/redis/data/6379 

logfile /opt/redis/log/redis_6379.log 

创建服务管理脚本 

vim /etc/init.d/redis 

#!/bin/sh 

PATH="/opt/redis/bin:$PATH" 

EXEC="/opt/redis/bin/redis-server" 

CLIEXEC="/opt/redis/bin/redis-cli" 

PIDFILE="/opt/redis/run/redis_6379.pid" 

CONF="/opt/redis/etc/redis_6379.conf" 

REDISPORT="6379" 



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 "Usage: $0 {start|stop}" >&2 

        exit 1 

        ;; 

esac 



授权 chmod +x /etc/init.d/redis 

vim /etc/sysctl.conf 

在最后添加以下节点: 

vm.overcommit_memory = 1 

sysctl –p 



启动redis 

/etc/init.d/redis start 

验证 

 ps aux | grep redis
