    Thank You a lot! The problem was that apache user must be placed in there like you said.

    CENTREON=nagios,centreon,nrpe,apache

    Just added apache (or www-data in other cases) and everything works perfect !

    Hi,

    Please check that rights are OK on the sudoers file.

    apache or www-data user must be placed here :

    CENTREON=nagios,centreon,nrpe,apache

    /etc/init.d/snmptt must be replace with /etc/init.d/snmptrapd also, just in case.

    Please let me know if it helps,

    B.R

    Can't restart Monitoring engine

    Hello,
    I have a problem when I'm trying to restart the Monitoring Engine.
    It returns this error:
    Code:
    sudo: no tty present and no askpass program specified

    I'm on Centos 6.5 64 bit. and using CES 3.0 repository. Centreon + Nagios + Ndoutils

    Here is my /etc/sudoers file
    Code:
     
    ## Sudoers allows particular users to run various commands as
    ## the root user, without needing the root password.
    ##
    ## Examples are provided at the bottom of the file for collections
    ## of related commands, which can then be delegated out to particular
    ## users or groups.
    ##
    ## This file must be edited with the 'visudo' command.
    
    
    ## Host Aliases
    ## Groups of machines. You may prefer to use hostnames (perhaps using
    ## wildcards for entire domains) or IP addresses instead.
    # Host_Alias     FILESERVERS = fs1, fs2
    # Host_Alias     MAILSERVERS = smtp, smtp2
    
    
    ## User Aliases
    ## These aren't often necessary, as you can use regular groups
    ## (ie, from files, LDAP, NIS, etc) in this file - just use %groupname
    ## rather than USERALIAS
    # User_Alias ADMINS = jsmith, mikem
    
    
    
    
    ## Command Aliases
    ## These are groups of related commands...
    
    
    ## Networking
    # Cmnd_Alias NETWORKING = /sbin/route, /sbin/ifconfig, /bin/ping, /sbin/dhclient, /usr/bin/net, /sbin/iptables, /usr/bin/rfcomm, /usr/bin/wvdial, /sbin/iwconfig, /sbin/mii-tool
    
    
    ## Installation and management of software
    # Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum
    
    
    ## Services
    # Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig
    
    
    ## Updating the locate database
    # Cmnd_Alias LOCATE = /usr/bin/updatedb
    
    
    ## Storage
    # Cmnd_Alias STORAGE = /sbin/fdisk, /sbin/sfdisk, /sbin/parted, /sbin/partprobe, /bin/mount, /bin/umount
    
    
    ## Delegating permissions
    # Cmnd_Alias DELEGATING = /usr/sbin/visudo, /bin/chown, /bin/chmod, /bin/chgrp
    
    
    ## Processes
    # Cmnd_Alias PROCESSES = /bin/nice, /bin/kill, /usr/bin/kill, /usr/bin/killall
    
    
    ## Drivers
    # Cmnd_Alias DRIVERS = /sbin/modprobe
    
    
    # Defaults specification
    
    
    #
    # Disable "ssh hostname sudo <cmd>", because it will show the password in clear.
    #         You have to run "ssh -t hostname sudo <cmd>".
    #
    Defaults    requiretty
    
    
    ## Refuse to run if unable to disable echo on the tty. This setting should also be
    # changed in order to be able to use sudo without a tty. See requiretty above.
    #
    Defaults   !visiblepw
    
    
    #
    # Preserving HOME has security implications since many programs
    # use it when searching for configuration files. Note that HOME
    # is already set when the the env_reset option is enabled, so
    # this option is only effective for configurations where either
    # env_reset is disabled or HOME is present in the env_keep list.
    #
    Defaults    always_set_home
    
    
    Defaults    env_reset
    Defaults    env_keep =  "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"
    Defaults    env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"
    Defaults    env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"
    Defaults    env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"
    Defaults    env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"
    
    
    #
    # Adding HOME to env_keep may enable a user to run unrestricted
    # commands via sudo.
    #
    # Defaults   env_keep += "HOME"
    
    
    Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin
    
    
    ## Next comes the main part: which users can run what software on
    ## which machines (the sudoers file can be shared between multiple
    ## systems).
    ## Syntax:
    ##
    ##      user    MACHINE=COMMANDS
    ##
    ## The COMMANDS section may have other options added to it.
    ##
    ## Allow root to run any commands anywhere
    root    ALL=(ALL)       ALL
    
    
    ## Allows members of the 'sys' group to run networking, software,
    ## service management apps and more.
    # %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS
    
    
    ## Allows people in group wheel to run all commands
    # %wheel        ALL=(ALL)       ALL
    
    
    ## Same thing without a password
    # %wheel        ALL=(ALL)       NOPASSWD: ALL
    
    
    ## Allows members of the users group to mount and unmount the
    ## cdrom as root
    # %users  ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom
    
    
    ## Allows members of the users group to shutdown this system
    # %users  localhost=/sbin/shutdown -h now
    
    
    ## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment)
    #includedir /etc/sudoers.d
    I Also have /etc/sudoers.d/centreon which is included in /etc/sudoers

    Code:
     ## BEGIN: CENTREON SUDO#Add by CENTREON installation script
    User_Alias      CENTREON=nagios,centreon,nrpe
    Defaults:CENTREON !requiretty
    ## Snmptrapd Restart
    CENTREON   ALL = NOPASSWD: /etc/init.d/snmptt restart
    ## CentStorage
    CENTREON   ALL = NOPASSWD: /etc/init.d/centstorage *
    # Nagios Restart
    CENTREON   ALL = NOPASSWD: /etc/init.d/nagios restart
