yum设置

cd /etc/yum.repos.d

mv CentOS-Base.repo  CentOS-Base.repo.save

wget http://centos.ustc.edu.cn/CentOS-Base.repo.5

mv CentOS-Base.repo.5 CentOS-Base.repo

rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

yum -y install yum-fastestmirror

 

安装一下程序包

yum -y install gcc glibc glibc-common gd gd-devel openssl-devel mysql-devel

 

 

安装apache

./configure --prefix=/fgn/theron/apache2 --enable-so --enable-mods-shared=most && make && make install

 

安装mysql

创建mysql账号和目录
userdel mysql
groupadd mysql
useradd mysql -d /fgn/theron/mysql -g mysql
mkdir -p /fgn/theron/mysql/data  /fgn/theron/mysql/tmp
chown -R mysql:mysql /fgn/theron/mysql
./configure '--prefix=/fgn/theron/mysql' '--with-unix-socket-path=/fgn/theron/mysql/tmp/mysql.sock' '--localstatedir=/fgn/theron/mysql/data' '--with-mysqld-user=mysql' '--without-debug' '--with-big-tables' '--with-charset=utf8' '--with-extra-charsets=all' '--with-pthread' '--enable-thread-safe-client' '--enable-assembler' '--without-ndb-debug--with-innodb' '--with-archive-storage-engine' '--with-client-ldflags=-all-static' '--with-readline' '--enable-local-infile'  && make && make install

如果安装双mysql,注意先移走/etc/my.cnf
./scripts/mysql_install_db --datadir=/fgn/theron/mysql/data --user=mysql
chown -R mysql:mysql /fgn/theron/mysql
mv  /etc/my.cnf /etc/my.cnf.bak
mv /usr/bin/mysql /usr/bin/mysql.bak
ln -s /fgn/theron/mysql/bin/mysql /usr/bin/mysql
chown -R mysql:mysql /fgn/theron/mysql

 

安装php
./configure --with-apxs2=/fgn/theron/apache2/bin/apxs  --prefix=/fgn/theron/php5  --with-mysql=/fgn/theron/mysql --with-config-file-path=/fgn/theron/php5/etc/ --with-libxml-dir=/usr --with-gd=/usr --with-pcre-regex --enable-mbstring=all --with-libmbfl --enable-gd-native-ttf --with-ttf --enable-gd-jis-conv --with-freetype-dir=/usr  --with-jpeg-dir=/usr --with-png-dir=/usr  --with-zlib-dir=/usr --enable-xml --enable-sockets --enable-ucd-snmp-hack && make && make install
cp php.ini-dist /fgn/theron/php5/lib/php.ini
添加路径/fgn/theron/php5/lib/php至/fgn/theron/php5/lib/php.ini

 

 

配置/fgn/theron/apache2/conf/httpd.conf

DocumentRoot "/usr/local/apache2/htdocs" ==> DocumentRoot "/fgn/theron/www"
==> 
DirectoryIndex index.html ==> DirectoryIndex index.html index.htm index.php index.phtml index.phps
LoadModule php5_module    modules/libphp5.so

加上此两行
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps
set-variable = max_connections=100

 

测试php

vim /fgn/theron/www/test.php

http://www.theron2.com:8080/test.php
http://ip:18080/test.php

 

 

创建nagios账号:
/usr/sbin/useradd nagios && passwd nagios 
/usr/sbin/groupadd nagcmd (创建一个用户组名为nagcmd用于从Web接口执行外部命令。将nagios用户和apache用户都加到这个组中)
/usr/sbin/usermod -G nagcmd nagios
/usr/sbin/usermod -G nagcmd daemon
/usr/sbin/usermod -G nagcmd apache

 

下载nagios core
wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.2.1.tar.gz

 

下载nagios plugs
wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.14.tar.gz

 

安装nagios

cd /fgn/theron/soft
tar zxf nagios-3.2.1.tar.gz 
cd nagios-3.2.1
./configure --with-command-group=nagcmd --prefix=/fgn/theron/nagios
make all 
make install 
make install-init 
make install-config 
make install-commandmode

 

安装nagios-plugins
cd /fgn/theron/soft
tar zxf nagios-plugins-1.4.14.tar.gz
cd nagios-plugins-1.4.14
./configure --with-nagios-user=nagios --with-nagios-group=nagios --prefix=/fgn/theron/nagios  && make && make install
验证
ls /fgn/theron/nagios/libexec

 

 

 

配置nagios的WEB接口 

方法一:直接在安装nagios时 make install-webconf 

创建一个nagiosadmin的用户用于Nagios的WEB接口登录。记下你所设置的登录口令,一会儿你会用到它。 

htpasswd -c /fgn/theron/nagios/etc/htpasswd.users nagiosadmin 

重启Apache服务以使设置生效。 

service httpd restart 

方法二:

创建vhost.conf

NameVirtualHost *:8080


    ServerName www.theron2.com
    ScriptAlias /nagios/cgi-bin /fgn/theron/nagios/sbin
    
    
    Options ExecCGI
    AllowOverride None
    Order allow,deny
    Allow from all
    AuthName "Nagios Access"
    AuthType Basic
    AuthUserFile /fgn/theron/nagios/etc/htpasswd
    Require valid-user
    

 

    Alias /nagios /fgn/theron/nagios/share

    
    Options None
    AllowOverride None
    Order allow,deny
    Allow from all
    AuthName "Nagios Access"
    AuthType Basic
    AuthUserFile /fgn/theron/nagios/etc/htpasswd
    Require valid-user
    


echo "conf/vhost.conf" >> ./httpd.conf
/fgn/theron/apache2/bin/htpasswd -c /fgn/theron/nagios/etc/htpasswd test 
New password: (输入12345) 
Re-type new password: (再输入一次密码) 
Adding password for user test 

查看认证文件的内容 

less /fgn/theron/nagios/etc/htpasswd
test:OmWGEsBnoGpIc 前半部分是用户名test,后面是加密后的密码 

本例添加的是test 用户名,需要改 cgi.cfg 配置文件,允许test用户 
authorized_for_system_information=test 
authorized_for_configuration_information=test 
authorized_for_system_commands=test 
authorized_for_all_services=test 
authorized_for_all_hosts=nagiosadmin,test 
authorized_for_all_service_commands=test 
authorized_for_all_host_commands=test 

如果有多用户,请用逗号格开 
重启apache

/fgn/theron/apache2/bin/apachectl restart

 

用账号test/12345登陆nagios:  
http://ip:18080/nagios/
http://www.theron2.com:18080/nagios/

 

 

#---client---#

下载nagios plugs
wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.14.tar.gz

 

安装nagios-plugins
useradd nagios
cd /fgn/theron/soft
tar zxf nagios-plugins-1.4.14.tar.gz

下载nrpe
wget http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.12.tar.gz

 

安装nrpe(安装nrpe插件,本监控端可以不装)
tar xzvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure --with-nagios-user=nagios --with-nagios-group=nagios  --prefix=/fgn/theron/nagios/
make all
make install-plugin
make install-daemon
make install-daemon-config
cp init-script /etc/init.d/nrpe
chmod 755 /etc/init.d/nrpe
chkconfig --add nrpe
chkconfig --level 3 nrpe on
