syslog-ng日志服务器搭建

热度：35   发布时间：2024-01-18 11:26:15.0

日志收集机器安装的就是syslog-ng，下面讲解一下syslog-ng的安装和配置步骤：

网上没有一个能够整体完成下来的，很多地方自己也不满意，就自己配置了一遍做了文档记录如下：


日志下载：
安装顺序：
1.eventlog--eventlog_0.2.12
地址：
https://my.balabit.com/downloads/eventlog/0.2/eventlog_0.2.12.tar.gz

2.libol---libol-0.3.15
地址：
https://my.balabit.com/downloads/libol/0.3/libol-0.3.15.tar.gz

3.syslog-ng--syslog-ng_3.3.5
地址：
https://my.balabit.com/downloads/syslog-ng/sources/3.3.5/source/syslog-ng_3.3.5.tar.gz

安装步骤：
1，安装eventlog
# tar -zxvf eventlog_0.2.12.tar.gz
# cd eventlog-0.2.12/
# ./configure   --prefix=/usr/local/eventlog && make && make install

# ls /usr/local/eventlog/ 
include   lib 

2.安装libol
# tar -zxvf libol-0.3.15.tar.gz
# cd libol-0.3.15/
# ./configure --prefix=/usr/local/libol

# ls /usr/local/libol/
bin  include  lib

3.安装syslog-ng
# tar -zxvf syslog-ng_3.3.5.tar.gz
# cd syslog-ng-3.3.5/

# export PKG_CONFIG_PATH=/usr/local/eventlog/lib/pkgconfig

# ./configure --prefix=/usr/local/syslog-ng --with-libol=/usr/local/libol

ls /usr/local/syslog-ng/ 
bin  etc  include  lib  libexec  sbin  share  var

cp ./contrib/syslog-ng.conf.RedHat /usr/local/syslog-ng/etc/  #---拷贝一个配置案例作为参考

#########配置自启动##########
# cp ./contrib/init.d.RedHat /etc/init.d/syslog-ng          #----拷贝自启动案例文件
# chmod +x /etc/init.d/syslog-ng
# chkconfig --add syslog-ng
service syslog-ng does not support chkconfig  #--------这个提示，请修改自启动文本

#/etc/init.d/syslog-ng--脚本头部增加以下几句代码作为声明
#!/bin/bash 
#chkconifg: --add syslog-ng 
#chkconfig: 2345 12 88 
#Description: syslog-ng

####----该脚本还需要修改下面的三个位置
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/syslog-ng/bin:/usr/local/syslog-ng/sbin

INIT_PROG="/usr/local/syslog-ng/sbin/syslog-ng"     # 服务运行地址
INIT_OPTS="-f /usr/local/syslog-ng/etc/syslog-ng.conf"     # 服务配置文件地址

###########自启动配置完成#########

##关闭旧syslog日志系统
service rsyslog stop
chkconfig --list rsyslog
chkconfig rsyslog off
