syslog-ng集中式日志服务配置

1.安装syslog-ng
# vi /usr/local/syslog-ng/etc/syslog-ng.conf
options {
        use_fqdn(yes);
        chain_hostnames(off);
        keep_hostname(off);
        sync(0);
        # The default action of syslog-ng 1.6.0 is to log a STATS line
        # to the file every 10 minutes.  That's pretty ugly after a while.
        # Change it to every 12 hours so you get a nice daily update of
        # how many messages syslog-ng missed (0).
        stats(43200);
        create_dirs(yes);
};
source s_internal { internal(); };
destination d_syslognglog { file("/var/log/syslog-ng.log"); };
log { source(s_internal); destination(d_syslognglog); };
source s_sys { file ("/proc/kmsg" log_prefix("kernel: ")); unix-stream ("/dev/log"); internal(); };
destination d_cons { file("/dev/console"); };
destination d_mesg { file("/var/log/messages"); };
destination d_auth { file("/var/log/secure"); };
destination d_mail { file("/var/log/maillog"); };
destination d_spol { file("/var/log/spooler"); };
destination d_boot { file("/var/log/boot.log"); };
destination d_cron { file("/var/log/cron"); };
destination d_rsync { file("/var/log/rsync"); };
destination d_mlal { usertty("*"); };
filter f_filter1     { facility(kern); };
filter f_filter2     { level(info) and
                     not (facility(mail)
                        or facility(authpriv) or facility(cron)); };
filter f_filter3     { facility(authpriv); };
filter f_filter4     { facility(mail); };
filter f_filter5     { level(emerg); };
filter f_filter6     { facility(uucp) or
                     (facility(news) and level(crit)); };
filter f_filter7     { facility(local7); };
filter f_filter8     { facility(cron); };
filter f_filter9     { facility(daemon); };
filter f_filter10     { facility(local6); };
#log { source(s_sys); filter(f_filter1); destination(d_cons); };
log { source(s_sys); filter(f_filter2); destination(d_mesg); };
log { source(s_sys); filter(f_filter3); destination(d_auth); };
log { source(s_sys); filter(f_filter4); destination(d_mail); };
log { source(s_sys); filter(f_filter5); destination(d_mlal); };
log { source(s_sys); filter(f_filter6); destination(d_spol); };
log { source(s_sys); filter(f_filter7); destination(d_boot); };
log { source(s_sys); filter(f_filter8); destination(d_cron); };
# Remote logging
source s_remote {
        udp(ip(0.0.0.0) port(514));
};

destination r_mesg { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/$HOST/messages" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_auth { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/$HOST/secure" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_mail { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/$HOST/maillog" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_spol { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/$HOST/spooler" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_boot { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/$HOST/boot.log" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_cron { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/$HOST/cron" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_daemon { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/$HOST/daemon" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
destination r_local6 { file("/var/log/syslog-ng/$YEAR$MONTH$DAY/network/messages" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes)); };
#destination d_separatedbyhosts {
#       file("/var/log/syslog-ng/$HOST/messages" owner("root") group("root") perm(0640) dir_perm(0750) create_dirs(yes));
#};
#log { source(s_remote); destination(d_separatedbyhosts); };
log { source(s_remote); filter(f_filter2); destination(r_mesg); };
log { source(s_remote); filter(f_filter3); destination(r_auth); };
log { source(s_remote); filter(f_filter4); destination(r_mail); };
log { source(s_remote); filter(f_filter6); destination(r_spol); };
log { source(s_remote); filter(f_filter7); destination(r_boot); };
log { source(s_remote); filter(f_filter8); destination(r_cron); };
log { source(s_remote); filter(f_filter9); destination(r_daemon); };
log { source(s_remote); filter(f_filter10); destination(r_local6); };

# syslog-ng conf file for use with phpsyslog-ng
#source src {
#  unix-stream("/dev/log" max-connections(256));
#  internal();
#  file("/proc/kmsg");
#  tcp();
#  udp();
#};
#
#log {
#  source(src);
#  destination(d_mysql);
#};
#
#destination d_mysql {
#  program("/usr/bin/mysql --user=root --password=  syslog < /var/log/mysql.pipe");
#  pipe("/var/log/mysql.pipe" template("INSERT INTO logs (host, facility, priority, level, tag, datetime, program, msg) VALUES ( '$HOST', '$FACILITY', '$PRIORITY', '$LEVEL', '$TAG', '$YEAR-$MONTH-$DAY $HOUR:$MIN:$SEC','$PROGRAM', '$MSG' );\n") template-escape(yes));
#};

把syslog-ng增加到开机启动
#echo "/usr/local/syslog-ng/sbin/syslog-ng" >> /etc/rc.local

2.安装tomcat和java环境请看本人另外的文章。这里主要讲log4j的相关配置，把日志发送给远程syslog-ng服务器

在tomcat的一个应用工程里面vi /.../WEB-INF/classes/log4j.properties
################ write to the file##################
log4j.rootLogger=info,debug,warn,syslog,A1
log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A1.file=/var/log/messages
#log4j.appender.A1.DatePattern=yyyy-MM-dd'.log'
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss, SSS}[%c]-[%p] %m%n
######################## write to the syslog ######################
# Appender to syslog
#log4j.rootCategory=INFO,DEBUG, CONSOLE, FILE, syslog
log4j.appender.syslog=org.apache.log4j.net.SyslogAppender
#log4j.appender.syslog.SyslogHost=192.168.76.100 （日志服务器的IP地址）       
log4j.appender.syslog.SyslogHost=127.0.0.1
log4j.appender.syslog.Port=514
log4j.appender.syslog.Facility=local5        
log4j.appender.syslog.layout=org.apache.log4j.PatternLayout        
log4j.appender.syslog.layout.ConversionPattern=%p: %c{2} - %m%n

修改本地syslog

vi /etc/syslog.conf
local5.*                                         @192.168.76.100（日志服务器的IP地址）

3.windows日志
windows日志不支持syslog格式
下载地址为：https://engineering.purdue.edu/ECN/Resources/Documents/UNIX/evtsys/

解压后是两个文件evtsys.dll和evtsys.exe
把这两个文件拷贝到 c:\windows\system32目录下。

打开Windows命令提示符（开始－>运行 输入CMD）
C:\>evtsys –i –h 192.168.76.100   #（日志服务器的IP地址）
-i 表示安装成系统服务
-h 指定log服务器的IP地址
如果要卸载evtsys,则：
net stop evtsys
evtsys -u

启动该服务:
C:\>net start evtsys

 

配置完成
