# sha256sum -c < sha256 V975367-01.iso: OKĪt this point, I mounted the server over a clear-text NFSv4.2 connection:ġ.2.3.4:/ /home/share nfs noauto,vers=4.2,proto=tcp,port=2049 0 0 I then verified the Oracle-supplied sha256 ISO hash on the client side in an effort to Rm: remove regular file '/home/share/V975367-01.iso' y I removed any copy of the ISO on the server from the previous test: # sync & echo 3 > /proc/sys/vm/drop_caches I made an attempt to clear the caches on both the client and server before sending The test involved pushing aĬopy of the Oracle Linux 7.5 install ISO to the server, under both clear-text NFS The Oracle Unbreakable Enterprise Kernel v4 (UEK). My test was performed on two HP D元60 G9 servers running recent releases of Trip back into userspace for the stunnel on each side, but the impact was far less I had expected a heavy speed penalty in forcing a Userspace NFS server under active development that is useful for specificĪpplications, notably FUSE). Moved into the kernel for Linux 2.2 to improve performance (there is still a Linux once had an NFS server implemented entirely in userspace, but this was Performed a few simple tests involving NFSv4 to make the penalty clear. To understand the price that must be paid for the encryption overhead, so I’ve Information cannot be allowed over clear-text connections. To obtain a Gluu Support contract, see support pricing.For those with real data security concerns, performance is irrelevant sensitive Note: This breaks SCIM functionality if one of the servers goes down and redundancy isn't built into the logic of your SCIM client It can be set to round-robin for load balancing across servers by changing nf to use backend instead of backend_id. The configuration file is located on the load balancing server (if installed) at /etc/nginx/nf. NGINX: used to proxy communication between Gluu instances. Restarting Twemproxy can be performed manually, or a script can be written to automate the task of resetting the "down" flag of the failed server Twemproxy will not reintroduce failed servers. Twemproxy enables high availability by automatically detecting Redis server failure and redirecting traffic to other working instances. It runs locally on port 2222 of the NGINX/Proxy server. The configuration file for this program can be found on the proxy server in /etc/nutcracker/nutcracker.yml. Twemproxy: used for cache failover, round-robin proxying and caching performance with Redis. Stunnel faciliates SSL communication over the Internet for Redis, which doesn't come default with encrypted traffic It runs on port 8888 of the NGINX/Proxy server and 7777 on the Gluu servers. The configuration file is located at /etc/stunnel/nf on all servers. Stunnel: used to protect communications between oxAuth and Redis and Twemproxy caching services. The configuration file is located on the servers with Gluu at /etc/redis/nf or /etc/nf Redis-Server: a value key-store known for it's high performance, installed outside the chroot on all servers. Gluu Server: free open source software package for identity and access management End-to-end secure tunneling between oxAuth and RedisĬluster Manager utilizes the following components:.Please report bugs or feature requests via the Gluu support portal. Gluu Cluster Manager Documentation # Overview #Ĭluster Manager is a GUI tool for installing and managing a highly available, clustered Gluu Server infrastructure.Ĭluster Manager is licensed under the Gluu Support License.
