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
