Rserve 설치하기

# install.packages('Rserve' , , 'http://www.rforge.net/')

※ 설치도중에 "cannot find -lssl"  에러가 발생된다면,  openssl-devel 를 설치하고 에러가 발생하지 않는다면
그냥 넘어가면 된다.  ( # yum install openssl-devel )

 

 

설치가 완료되면 R콘솔에서 Rserve를 실행한다.

> library(Rserve)
> Rserve()

Starting Rserve:
/usr/lib64/R/bin/R CMD /usr/lib64/R/library/Rserve/libs//Rserve

원격 호출을 사용하려면 설정 추가가 필요하다.

/etc 폴더로 이동후 vi 명령어를 통해 "Rserv.conf" 파일을 생성하고, 내용은 다음과 같이 구성한다.

# vi Rserv.conf

remote enable
port 6311
plaintext enable
auth required
pwdfile /etc/Ruser.txt
encoding utf8

 

 

/etc/Ruser.txt ( userid / userpw  계정을 추가한다.)

# vi Ruser.txt

userid userpw

 

 

외부에서 6311 포트 사용을 위해 방화벽 작업으로 접속을 허용해야 한다.

# firewall-cmd --permanent --zone=public --add-port=6311/tcp
# firewall-cmd --reload

 

 

Rserve 의 구성이 바뀌었으므로, 프로세스를 kill 하고 다시 실행해야 한다.

# ps -ef | grep Rserve

root  23819          1  0 13:38 ? 00:00:00 /usr/lib64/R/library/Rserve/libs//Rserve
root  24966  30888  0 13:57 pts/2 00:00:00 grep --color=auto Rserve

# kill -9 23819

 

 

R콘솔에서 Rserve를 실행한다.

> library(Rserve)
> Rserve(port=6311, args="--RS-conf /etc/Rserv.conf --no-save")

Starting Rserve on port 6311 :
/usr/lib64/R/bin/R CMD /usr/lib64/R/library/Rserve/libs//Rserve --RS-conf /etc/Rserv.conf --no-save --R S-port 6311
