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

memcached-tool 127.0.0.1:11211 stats

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
