CentOS 安装 Memcached

安装 & 配置
wget http://memcached.org/latest -O memcached.tar.gz
tar -zxvf memcached.tar.gz
cd memcached
./configure –prefix=/usr/local/memcached
make && sudo make install
ln -sf /usr/local/memcached/bin/memcached /usr/bin/memcached

如果不存在 `/var/lock/subsys`，则创建 `mkdir -p /var/lock/subsys`

赋予可执行权限：chmod +x /etc/init.d/memcached

防火墙设置
# 设置规则
vim /etc/sysconfig/iptables

# 如果限定某些机器能访问可如下设置：
-A INPUT -s 127.0.0.1,10.170.238.137,123.7.213.222/32 -p udp -m udp –dport 11211 -j ACCEPT
-A INPUT -s 127.0.0.1,10.170.238.137,123.7.213.222/32 -p tcp -m tcp –dport 11211 -j ACCEPT
-A INPUT -p tcp -m tcp –dport 11211 -j DROP
-A INPUT -p udp -m udp –dport 11211 -j DROP

# 重启 iptables 使得规则生效
service iptables restart
