Hi,  
I want to installation ES 5.0.0 on CEntos 6.7

I installed jdk 8u73

`sudo yum install jdk-8u73-linux-x64.rpm`

and I installed ES 5.0.0

`sudo yum install elasticsearch-5.0.0.rpm`

and

`/bin/elasticsearch`

my error:

```
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x000000008a660000, 1973026816, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 1973026816 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /usr/share/elasticsearch/hs_err_pid23640.log

```

What can I do?

Change memory settings or add more memory to your computer.
