redis(二)redis+TCMALLOC高性能的缓存服务器的安装配置

redisTCMALLOC 
阅读更多
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
