LinuCエヴァンジェリストの鯨井貴博@opensourcetechです。
CentOS6で利用していたchkconfigと、CentOS7から使っているsystemctlの対比に関するメモです。
まず、chkconfigは「chkconfig --list」とすると、
OS起動時に立ち上がるプログラム(ランレベル毎)が分かるようになっています。
「chkconfig プログラム on/off」で起動する/起動しないの設定ができます。
CentOS7以降のsystemctlでも同様のことを「systemctl」でできますが、
chkconfigよりオプションで細かい使い分けができるようになっています。
