搭建syslog服务器流程

1.安装系统a)安装要求i.PC配置：CPU：IntelPE2160（1.8GHz）以上内存：1G以上硬盘：80G以上虚拟机要求：Kernel：linux2.6内存：512以上硬盘：40G以上b)安装系统i.Linuxsyslogserver要求用centos5.5下载地址：ed2k://|file|[《CentOS.5.5.》32bit[光盘镜像]].CentOS-5.5-i386-bin-DVD.iso|4185118720|a1ce64b6d36d945f562cb1250d8d665f|h=fnfai2pqdbdxmz5i5wshkaj22ttscbkg|/c)配置网络i.点击桌面上方的系统管理网络，配置eth0和DNSii.NetworkAbapter修改为桥接模式2.安装工具a)安装GCC和make[root@FDWIN~]#yuminstallgccmakeb)安装LAMP平台[root@FDWIN~]#yuminstallphp-mysqlmysqlmysql-serverphp-snmpphp-pdoperl-DBDMySQLhttpdphp–y[root@FDWIN~]#servicemysqldstart[root@FDWIN~]#chkconfigmysqldon[root@FDWIN~]#servicehttpdstart[root@FDWIN~]#chkconfighttpdon[root@FDWIN~]#mysqladmin-urootpassword'000000'[root@FDWIN~]#vim/var/添加：?php$link=mysql_connect(localhost,root,000000);if(!$link)echoFAILD!;elseechoOK!;?然后网页访问下出现OK说明没问题了。进入centos的DVD盘然后安装rpm-vihphp-gd-5.1.6-15.el5.i386.rpm进入centos的DVD盘然后安装rpm-ivhfreetype-2.2.1-19.el5.i386.rpmc)安装NET-SNMP1.下载net-snmp源码，并解压[root@FDWINproc]#wget[root@FDWINproc]#tar-xvzfnet-snmp-5.6.tar.gz2.Configurea)进入源文件目录[root@FDWINproc]#cdnet-snmp-5.6b)Configure[root@FDWINproc]#./configure--prefix=/usr/local/net-snmp–enable-mfd-rewrites--with-default-snmp-version=”2”--with-persistent-directory=”/var/net-snmp”3.编译、安装[root@FDWINproc]#make&&makeinstall4.配置snmpd.confa)将EXAMPLE.conf文件复制到/usr/local/net-snmp/share/snmp/snmpd.conf[root@FDWINproc]#cpEXAMPLE.conf/usr/local/net-snmp/share/snmp/snmpd.confb)修改snmpd.conf1.查找以下字段：#sec.namesourcecommunitycom2secnotConfigUserdefaultpublic将comunity字段改为你要设置的密码.比如bizcnpublic.将“default”改为你想哪台机器可以看到你的snmp信息,如10.10.10.10。授权服务器IP2.查找以下字段：#####Finally,grantthegroupread-onlyaccesstothesystemviewview.#groupcontextsec.modelsec.levelprefixreadwritenotifaccessnotConfigGroupanynoauthexactsystemviewnonenone将read字段改为all.代码:#accessnotConfigGroupanynoauthexactallnonenone3.查找以下字段：##incl/exclsubtreemask#viewallincluded.180将该行前面的#去掉.4.查找以下字段：#nameincl/exclsubtreemask(optional)添加一行viewallincluded.1变成#nameincl/exclsubtreemask(optional)viewallincluded.15.查找以下字段：#viewmib2included.iso.org.dod.internet.mgmt.mib-2fc将该行前面的#去掉.保存、关闭c)设置net-snmp自启动[root@FDWINproc]#chkconfig--level35snmpdon[root@FDWINproc]#chkconfig--addsnmpdd)SNMP测试（本机）[root@FDWINproc]#snmpwalk-v-2c-cpublicFDWIN若有大量数据返回，说明SNMP配置正确e)防火墙打开udp161端口f)检查SNMP服务是否运行[root@FDWINproc]#netstat-ln|grep161udp00127.0.0.1:1610.0.0.0:*表示SNMP已运行正常3.CACTI安装a)RRDtool的安装1.cgilibwget://://cairographics.org/releases/pixman-0.21.2.tar.gzcdpixman-0.21.2./configuremake;makeinstall4.cairowget=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH#这里很重要./configuremake;makeinstall5.pangowget://–prefix=/usr/local/rrdtoolmake;makeisntallb)Cacti的安装1.下载Cacti软件包，并安装到/var/://配置数据库mysql-uroot-p123456mysqlcreatedatabasecacti;mysqlgrantallprivilegesoncacti.*tocacti@FDWINidentifiedby'cacti'withgrantoption;mysqlgrantallprivilegesoncacti.*tocacti@127.0.0.1identifiedby'cacti'withgrantoption;mysqlflushprivileges;mysqlusecacti;mysqlsource/var/配置Cacti以连接数据库vi/var/依照如下修改：/*makesurethesevaluesrefectyouractualdatabase/host/user/password*/$database_type=mysql;$database_default=cacti;$database_hostname=FDWIN;$database_username=cacti;$database_password=cacti;$database_port=3306;vi/var/依照如下修改：/*Defaultdatabasesettings*/$database_type=mysql;$database_default=cacti;$database_hostname=FDWIN;$database_username=cacti;$database_password=cacti;$database_port=3306;$config['url_path']='/cacti/';4.添加cacti用户[root@FDWINproc]#useradd-snologincacti[root@FDWINproc]#passwdcacti5.修改cacti目录属主[root@FDWINproc]#chown-Rcacti:cacti/var/编辑crontab[root@FDWINproc]#crontab-e*/5****/usr/bin/php/var/关闭SELinux[root@FDWINproc]#setenforce08.用浏览器访问配置Cacti首先点开settings的path页，正确设置相应的路径，然后finish保存10.安装补丁按照Cacti.net上的步骤，打上补丁程序必须在Cacti的安装目录下，即/var/[root@FDWINproc]#wget[root@FDWINproc]#wget[root@FDWINproc]#wget[root@FDWINproc]#w
