  • CentOS7安装Memcached 三步曲

    1.yum 安装

    yum clean all
    yum -y update
    yum -y install memcached

    2.Memcached 运行

    memcached -h

    //查看考号修改配置
    vim /etc/sysconfig/memcached
    内容如下:
    PORT=”11211″
    USER=”memcached”
    MAXCONN=”1024″
    CACHESIZE=”64″
    OPTIONS=”"

    可以修改端口,用户和最大内存,缓存大小
    //重启,启动,开机启动,状态,关闭
    systemctl restart memcached
    systemctl start memcached
    systemctl enable memcached
    systemctl status memcached
    systemctl stop memcached

    3.扩展一下,安装PHP-memcache扩展,防火墙放开11211端口

    yum -y install php-pecl-memcache
    如果是PHP56版本的应该运行
    yum -y install php56w-pecl-memcache
    防火墙放开11211
    firewall-cmd --permanent --zone=public --add-port=11211/tcp
    检查端口是否开放
    echo stats | nc memcache_host_name_or_ip 11211
