添加如下配置到 /etc/bashrc 文件末尾

up_client_ip=`(who am i|cut -d\( -f2|cut -d\) -f1)`
logger -p local5.info -- $up_client_ip,$(whoami),$$
export PROMPT_COMMAND='{ msg=$(history 1 | { read x y; echo $y; });logger -p user.notice "[euid=$(whoami)]",$(who am i),`pwd`",$msg"; }'
readonly PROMPT_COMMAND


重新登录生效


添加如下配置到 /etc/rsyslog.conf 文件末尾

$template StdLOGFormat,"%fromhost%||%syslogfacility-text%||%syslogpriority-text%||%timereported:::date-mysql%||%timegenerated:::date-mysql%||%msg%||%iut%||%programname%||%syslogtag%"

安装logstash 步骤省略

logstash 配置文件 /etc/logstash/conf.d/sys.conf 内容如下：

input {
    syslog {

        type => "rsyslog"
    }
}

filter {

        urldecode {  # 编码转换
            all_fields=>true
        }
        mutate {
            split => ["message","||"]  # 拆分日志
            add_field => {"HostName" => "%{message[0]}"}
            add_field => {"Facility" => "%{message[1]}"}
            add_field => {"Mes" => "%{message[5]}"} 
            remove_field => ["message","facility_label","facility","severity_label","severity","priority","timestamp","program"]
        }
        if [Facility] == "local5" {
        mutate {
            split => ["Mes",","]  # 拆分日志
            add_field => {"ClientIp" => "%{Mes[0]}"}

            }            
        }
        if [Facility] == "user" {
        mutate {
            split => ["Mes",","]  # 拆分日志

            }
        }
    }
}

output {
