  • redis安装

    直接看官网:

    wget http://download.redis.io/releases/redis.tar.gz
    tar xzf redis.tar.gz
    cd redis
    make

    简单使用:

    启动服务:
    src/redis-server redis.conf
    
    启动客户端:
    src/redis-cli
    redis> set foo bar
    OK
    redis> get foo
    "bar"

    主要配置项(redis.conf):

    port 6379
    pidfile /var/run/redis_6379.pid
    logfile "/opt2/app/logs/redis/redis02.log"
    maxmemory 10G
    maxmemory-policy allkeys-lru
    
    
    aof-rewrite-incremental-fsync yes
    requirepass   xxxx
    stop-writes-on-bgsave-error no
    
    #daemonize 如果需要在后台运行,把该项改为 yes
    daemonize yes

    LINUX内核参数调整(不调整 REDIS启动会有一系列报警):

    性能:
    1 vi /etc/sysctl.conf 
     添加 vm.overcommit_memory = 1
     生效:sysctl vm.overcommit_memory=1
    
    2
    echo never > /sys/kernel/mm/transparent_hugepage/enabled
    
    vi /etc/rc.local 
    transparent_hugepage=never
    
    3
    echo 511 > /proc/sys/net/core/somaxconn
    

    REDIS启动:

    # daemonize 已经设为 yes
    ./src/redis-server redis.conf
    
    
    # daemonize 未设为 yes
    ./src/redis-server redis.conf &

    REDIS关闭:

    # 关闭所有REDIS进程
    pkill redis
    
    #更友好的关闭REDIS
    /usr/local/redis/bin/redis-cli shutdown

    REDIS监控,程序挂掉自启:
