CentOS环境memcached安装

1.Memcached安装

tar -zxvf libevent-2.0.22-stable.tar.gz
cd libevent-2.0.22-stable
./configure --prefix=/usr/local/libevent
make && make install

tar -zxvf memcached-1.4.25.tar.gz
cd memcached-1.4.25
./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent
make && make install

2.Memcached配置

• 添加启动文件(文章后面有)
  /etc/init.d/memcached
• 查看防火墙是否开启。

systemctl start firewalld
systemctl stop firewalld
systemctl status firewalld

• 开启防火墙11211端口

firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="x.x.x.x" port protocol="tcp" port="11211" accept"
firewall-cmd --reload

• 添加开机启动

chkconfig memcached on

• 启动memcached

service memcached restart

解决“can't find the user memcached to switch to”问题

useradd memcached
