Install FUSE-Based POSIX Client

Describes how to install the FUSE-based POSIX client package on your system.

FUSE based POSIX clients require the FUSE kernel module. Run the following command to load the kernel module: modprobe fuse

You can install the FUSE-based POSIX client on any node, including cluster nodes.

To install the mapr-posix-client-* package on your machine, where * refers to the basic or the platinum client package, perform the following steps for your version of Linux, as the root user, or using sudo. The package is installed to the /opt/mapr/bin/ directory.

Run the following command to install the POSIX client package on your machine.

For CentOS, RedHat, or Oracle Linux

# yum install mapr-posix-client-*, where * is either the basic or the platinum package
For example: yum install mapr-posix-client-basic

Troubleshooting: On Oracle Linux, you must also install the compat-openssl10 package to get the POSIX client running.

Run:

yum install compat-openssl10

For Suse

# zypper install mapr-posix-client-*, where * is either the basic or the platinum package
For example: zypper install mapr-posix-client-basic

For Ubuntu

# sudo apt-get install mapr-posix-client-*, where * is either the basic or the platinum package
For example: apt-get install mapr-posix-client-basic

Run configure.sh to set this node as the client node.
- For a fresh installation of the POSIX client, run configure.sh as follows:
```
/opt/mapr/server/configure.sh -N <clustername> -C <CLDBhost> -Z <ZooKeeperhost> -c
```
- When reinstalling the POSIX client, run configure.sh with the -R option to reuse the existing configuration.
```
/opt/mapr/server/configure.sh -c -R 
```
Note: To use the POSIX client with a secure cluster, add the -secure option when running configure.sh. However, do NOT add the -secure option when running configure.sh with the -R option.

To use the client:
