16G存储

源码包下载：第一部分：下载，第二部分：下载

1.安装snmp：

 yum install -y net-snmp net-snmp-devel net-snmp-utils
 yum install -y gcc gcc-c++  libtool*

配置snmp：

删除/etc/snmp/snmpd.conf配置文件中所有内容，粘贴如下内容到配置文件

com2sec notConfigUser  default       public

group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser

view mib2   included  .iso.org.dod.internet.mgmt.mib- fc

view    systemview    included   .1.3.6.1.2.1.
view    systemview    included   .1.3.6.1.2.1.
view    systemview    included   .1.3.6.1.2.1.25.1.

access  notConfigGroup ""      any       noauth    exact  mib2 none none

syslocation Unknown (edit /etc/snmp/snmpd.conf)

syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)

启动SNMP：

准备好安装包：

2.安装zlib：

[root@localhost software]# tar -zxf zlib-1.2..tar.gz
[root@localhost zlib-1.2.]# ./configure --prefix=/usr/local/zlib
[root@localhost zlib-1.2.]# make
[root@localhost zlib-1.2.]# make install

3安装apache：

root@localhost httpd-2.2.]# ./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-usertrack --enable-rewrite --with-z=/usr/local/zlib

root@localhost httpd-2.2.]# make && make install

配置apache：

修改配置文件中的ServerName 127.0.0.1

启动apache：

[root@localhost software]# /usr/local/apache/bin/apachectl -k restart

4.安装libpng：

[root@localhost software]# tar -zxf libpng-1.2..tar.gz
[root@localhost software]# cd libpng-1.2.

[root@localhost libpng-1.2.]# cp scripts/makefile.linux makefile

修改makefile指定的zlib的路径：

[root@localhost libpng-1.2.]# make
[root@localhost libpng-1.2.]# make install

5.安装freetype：

[root@localhost software]# tar -zxf freetype-2.1..tar.gz
[root@localhost software]# cd freetype-2.1.
[root@localhost freetype-2.1.]# mkdir -p /usr/local/freetype
[root@localhost freetype-2.1.]# ./configure --prefix=/usr/local/freetype
[root@localhost freetype-2.1.]# make
[root@localhost freetype-2.1.]# make install

6.安装jpeg：

[root@localhost software]# tar -zxf jpegsrc.v6b.tar.gz
[root@localhost software]# cd jpeg-6b/
[root@localhost jpeg-6b]#
jpeg默认不会自动创建安装目录手动创建：
[root@localhost jpeg-6b]# mkdir -pv /usr/local/jpeg6/{,bin,lib,include,man/{,man1},man1}
mkdir: created directory `/usr/local/jpeg6/'
mkdir: created directory `/usr/local/jpeg6/bin'
mkdir: created directory `/usr/local/jpeg6/lib'
mkdir: created directory `/usr/local/jpeg6/include'
mkdir: created directory `/usr/local/jpeg6/man/'
mkdir: created directory `/usr/local/jpeg6/man/man1'
mkdir: created directory `/usr/local/jpeg6/man1'
[root@localhost jpeg-6b]#
[root@localhost jpeg-6b]# cp /usr/share/libtool/config/config.sub  /root/software/jpeg-6b/      #copy系统下libtool下的这两个文件覆盖jpeg下同
cp: overwrite `/root/software/jpeg-6b/config.sub'? y                                            #样的文件
[root@localhost jpeg-6b]# cp /usr/share/libtool/config/config.guess  /root/software/jpeg-6b/
cp: overwrite `/root/software/jpeg-6b/config.guess'? y
[root@localhost jpeg-6b]#
[root@localhost jpeg-6b]# ./configure  --prefix=/usr/local/jpeg6/ --enable-shared --enable-static
[root@localhost jpeg-6b]# make

[root@localhost jpeg-6b]# make install

7.安装libxml2：

[root@localhost software]# tar -zxf libxml2-2.6..tar.gz
[root@localhost software]# cd libxml2-2.6.
[root@localhost libxml2-2.6.]# mkdir -p /usr/local/libxml2
[root@localhost libxml2-2.6.]# ./configure  --prefix=/usr/local/libxml2
[root@localhost libxml2-2.6.]# make
[root@localhost libxml2-2.6.]# make install

8.安装gd：

[root@localhost gd-2.0.]# tar -zxf gd-2.0..tar.gz
[root@localhost gd-2.0.]# ./configure  --prefix=/usr/local/gd2 --with-png=/usr/local/lib --with-zlib=/usr/local/zlib --with-freetype=/usr/local/freetype --with-jpeg=/usr/local/jpeg6
[root@localhost gd-2.0.]# make
[root@localhost gd-2.0.]# make install

9.安装mrtg：

[root@localhost software]# tar -zxf mrtg-2.15..tar.gz
[root@localhost software]# cd mrtg-2.15.
[root@localhost software]# mkdir /etc/mrtg
[root@localhost mrtg-2.15.]# ./configure --prefix=/usr/local/mrtg --sysconfdir=/etc/mrtg --with-gd=/usr/local/gd2/include --with-gd-lib=/usr/local/gd2/lib --with-gd-inc=/usr/local/gd2/include  --with-png=/usr/local/include --with-png-lib=/usr/local/lib --with-png-inc=/usr/local/include --with-zlib=/usr/local/zlib/include --with-zlib-lib=/usr/local/zlib/lib  --with-zlib-inc=/usr/local/zlib/include
[root@localhost mrtg-2.15.]# make
[root@localhost mrtg-2.15.]# make install
[root@localhost ~]# /usr/local/mrtg/bin/cfgmaker public@localhost > /etc/mrtg/mrtg.cfg

[root@localhost ~]# 

10.修改MRTG配置文件：

[root@localhost ~]# vi /etc/mrtg/mrtg.cfg 

11.新建网页文件存放目录：

[root@localhost ~]# mkdir /usr/local/apache/htdocs/mrtg

12.生成网页文件：

[root@localhost ~]# /usr/local/mrtg/bin/indexmaker /etc/mrtg/mrtg.cfg --output=/usr/local/apache/htdocs/mrtg/index.html --title="MY MRTG"
[root@localhost ~]#
[root@localhost ~]# cd /usr/local/apache/htdocs/mrtg/
[root@localhost mrtg]# ls
index.html

.启动MRTG：
[root@localhost ~]# env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg
-- ::, Rateup WARNING: /usr/local/mrtg/bin/rateup could not read the primary log file for localhost_2
-- ::, Rateup WARNING: /usr/local/mrtg/bin/rateup The backup log file for localhost_2 was invalid as well
-- ::, Rateup WARNING: /usr/local/mrtg/bin/rateup Can't remove localhost_2.old updating log file
-- ::, Rateup WARNING: /usr/local/mrtg/bin/rateup Can't rename localhost_2.log to localhost_2.old updating log file
[root@localhost ~]# env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg
-- ::, Rateup WARNING: /usr/local/mrtg/bin/rateup Can't remove localhost_2.old updating log file
[root@localhost ~]# env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg
[root@localhost ~]#

PS:上面env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg 命令会有错误信息输出，忽略执行三次命令即可

因为mrtg生成的是静态html文件，不断刷新则需要加入计划任务：

重启计划任务：

访问mrtg：

在浏览器输入：http://x.x.x.x/mrtg

MRTG配置文件mrtg.cfg配置文件中参数说明：

mrtg.cfg 里面几个参数的意思.
Target：是要执行的脚本
Xsize：生成图表的横向宽度（最大600）
Ysize：生成图表的纵向高度（最大200）
Title：标题
kMG: Change the default multiplier prefixes
 Ytics：纵向划分为几个块（格子）
MaxBytes：图表纵向数值的最大上限
PageTop：页面上面的提示
kilo：一般是写1024，如果需要的话，是1000在计算机里的单位
LegendI：从SHELL返回的数据中的第一个
LegendO：从SHELL返回的数据中的第二个
Options： growright，表示图表向右延展
