（二）、NFS服务端部署
中小型规模网站集群架构:NFS-Server部署
： Ago linux运维群：https://hankbook.cn
1.整体思路
服务端：
- 安装nfs
- yum install -y nfs-utils rpcbind
- 目录
- /data
- 权限：755
- 所有者(组)：www ID为888
useradd -s /sbin/nologin -M -u 888 www
- 配置文件/etc/exports
- 优化：
- anonuid = 888
- anongid = 888
/data 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
客户端：
- 优化：
- 挂载参数
- mount -t nfs -o nosuid,noexec,nodev,noatime,nodiratime,rsize=131071,wsize=131072
- 内核参数
cat >> /etc/sysctl.conf << EOF
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
EOF
2.具体部署
配置文件nfs_exports
/nfsdata/dedecms 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
/nfsdata/discuz 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
/nfsdata/wordpress 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
