 -bash-3.2# startsrc -s named 
 0513-059 The named Subsystem has been started. Subsystem PID is 372810. 

修改文件大小限制。因为用于安装节点所用的各种 AIX/NIM 资源文件一般都比较大,所以有必要将 root 帐号的文件限制设置为不限制。在这里,可以使用 chuser 命令,参数 fsize=-1 表示对大小没有限制:

-bash-3.2# /usr/bin/chuser fsize=-1 root 

检查 xCAT 所依赖的系统服务是否正常运行。查看 /etc/inetd.conf 文件,检查 inetd 服务是否已经包含 telnet, ftp, bootp/dhcp 等等服务,还要检查用于给各个集群节点安装系统时候需要的 NFS 和 TFTP 服务是否正常运行。可以使用 lssrc 命令查看各个服务是否处于 active 状态:

-bash-3.2# lssrc -ls inetd 
 Subsystem     Group      PID     Status 
 inetd      tcpip      229540    active 
 Debug     Not active 
 Signal    Purpose 
 SIGALRM   Establishes socket connections for failed services. 
 SIGHUP    Rereads the configuration database and reconfigures services. 
 SIGCHLD   Restarts the service in case the service ends abnormally. 
 Service    Command         Description       Status 
 pmv5     /etc/pmdv5        pmdv5          active 
 xmquery   /usr/bin/xmtopas     xmtopas -p3       active 
 wsmserver  /usr/websm/bin/wsmserver wsmserver -start     active 
 time     internal                     active 
 daytime   internal                     active 
 time     internal                     active 
 daytime   internal                     active 
 ntalk    /usr/sbin/talkd     talkd          active 
 tftp     /usr/sbin/tftpd     tftpd -n         active 
 bootps    /usr/sbin/bootpd     bootpd /etc/bootptab   active 
 exec     /usr/sbin/rexecd     rexecd          active 
 login    /usr/sbin/rlogind    rlogind         active 
 shell    /usr/sbin/rshd      rshd           active 
 telnet    /usr/sbin/telnetd    telnetd -a        active 
 ftp     /usr/sbin/ftpd      ftpd           active 
 -bash-3.2# lssrc -s nfsd 
 Subsystem     Group      PID     Status 
 nfsd       nfs       307350    active 
 -bash-3.2# lssrc -s tftpd 
 Subsystem     Group      PID     Status 
 tftpd      tcpip      315546    active
