service httpd status 실행시 에러

1. service httpd status 실행시 아래와 같은 에러가 발생합니다.

[root@localhost network-scripts]# service httpd status
/etc/init.d/httpd: line 97: lynx: command not found

잘 사용하던 명령어인데 무슨 작업탓인지? 실행이 안됩니다.
httpd에 대해서만 저런 에러가 발생합니다...


2. system-config-network / system-config-network-tui 실행시 아래 메시지

위의 명령어도 잘 사용하던 중 실행이 되지 않습니다.


혹시 위와 같은 에러에 대응하는 방법을 아시는분 조언 부탁드립니다.
좋은 하루 되세요~
