首先我们给opt的目录赋予写的权限

sudo chmod a+w /opt

然后执行source /etc/profile

然后退出机器的时候，再次进入的时候  /opt/history下面就会有文件产生

admin.history

然后我们再把相应的权限改回来

写成脚本使用ansible批量部署到其他的机器上

• #!/bin/bash
  sudo chmod a+w /opt
  cat <<EOF>>/etc/profile
  #history
  USER_IP=\`who -u am i 2>/dev/null| awk ‘{print \$NF}‘|sed -e ‘s/[()]//g‘\`
  if [ "\$USER_IP" = "" ]
  then
  USER_IP=\`hostname\`
  fi
  if [ ! -d /opt/history ]
  then
  mkdir /opt/history
  chmod 777 /opt/history
  fi
  if [ ! -d /opt/history/\${LOGNAME} ]
  then
  mkdir /opt/history/\${LOGNAME}
  chmod 300 /opt/history/\${LOGNAME}
  fi
  export HISTSIZE=4096
  export HISTTIMEFORMAT="%F %T $USER_IP:\`whoami\` "
  export HISTFILE="/opt/history/\${LOGNAME}.history"
  chmod 600 /opt/history/*history* 2>/dev/null
  EOF
  source /etc/profile
  sudo chmod o-w /opt

#history
USER_IP=`who -u am i 2>/dev/null| awk ‘{print $NF}‘|sed -e ‘s/[()]//g‘`
if [ "$USER_IP" = "" ]
then
USER_IP=`hostname`
fi
if [ ! -d /opt/history ]
then
mkdir /opt/history
chmod 777 /opt/history
fi
if [ ! -d /opt/history/${LOGNAME} ]
then
mkdir /opt/history/${LOGNAME}
chmod 300 /opt/history/${LOGNAME}
fi
export HISTSIZE=4096
export HISTTIMEFORMAT="%F %T $USER_IP:`whoami` "
export HISTFILE="/opt/history/${LOGNAME}.history"
chmod 600 /opt/history/*history* 2>/dev/null
