基于Nginx平台部署Nagios监控系统
环境：CentOS 6.5（最小化安装）
Nginx：1.6.2
Nagios：3.3.1
安装基本环境：

php启动错误解决方法：http://yfshare.blog.51cto.com/8611708/1635679
安装Nginx：
[[email protected] software]# tar -jxvf pcre-8.12.tar.bz2 &>/dev/null [[email protected] software]# cd pcre-8.12 [[email protected] pcre-8.12]# ./configure &&make &&make install zlib上面安装php时已安装 [[email protected] software]# tar -zxvf openssl-1.0.1c.tar.gz &>/dev/null [[email protected] software]# cd openssl-1.0.1c [[email protected] openssl-1.0.1c]# ./config &&make &&make install [[email protected] software]# tar -zxvf nginx-1.6.2.tar.gz &>/dev/null [[email protected] software]# cd nginx-1.6.2 [[email protected] nginx-1.6.2]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-pcre=/software/pcre-8.12 --with-zlib=/software/zlib-1.2.7 --with-openssl=/software/openssl-1.0.1c --with-http_stub_status_module [[email protected] nginx-1.6.2]# make &&make install
编写/etc/init.d/nginx文件
[[email protected] nginx-1.6.2]# /etc/init.d/nginx start
Starting nginx: [ OK ]
[[email protected] nginx-1.6.2]#
[[email protected] nginx-1.6.2]# chkconfig --add nginx [[email protected] nginx-1.6.2]# chkconfig nginx on [[email protected] conf]# ln -s /usr/local/nagios/share /usr/local/nginx/html/nagios
[[email protected] conf]# ll /usr/local/nginx/html/
total 8
-rw-r--r-- 1 root root 537 Apr 18 10:59 50x.html
-rw-r--r-- 1 root root 612 Apr 18 10:59 index.html
lrwxrwxrwx 1 root root 23 Apr 18 12:43 nagios -> /usr/local/nagios/share
还需要自己编写nginx.conf、fastcgi.conf、cgi.conf、start_perl_cgi.sh、perl-fcgi.pl
[[email protected] conf]#
给Nginx添加对Perl的CGI支持（默认不支持）：
安装FCGI模块：
[[email protected] software]# tar -zxvf FCGI-0.73.tar.gz &>/dev/null [[email protected] software]# cd FCGI-0.73 [[email protected] FCGI-0.73]# perl Makefile.PL &&make &&make install [[email protected] software]# tar -zxvf FCGI-ProcManager-0.25.tar.gz &>/dev/null [[email protected] software]# cd FCGI-ProcManager-0.25 [[email protected] FCGI-ProcManager-0.25]# perl Makefile.PL &&make &&make install [[email protected] software]# tar -zxvf IO-1.25.tar.gz &>/dev/null [[email protected] software]# cd IO-1.25 [[email protected] IO-1.25]# perl Makefile.PL &&make &&make install [[email protected] software]# tar -zxvf IO-All-0.39.tar.gz &>/dev/null [[email protected] software]# cd IO-All-0.39 [[email protected] IO-All-0.39]# perl Makefile.PL &&make &&make install [[email protected] software]# tar -zxvf spawn-fcgi-1.6.3.tar.gz &>/dev/null [[email protected] software]# cd spawn-fcgi-1.6.3 [[email protected] spawn-fcgi-1.6.3]# ./configure &&make &&make install [[email protected] software]# unzip perl-fcgi.zip [[email protected] software]# cp perl-fcgi.pl /usr/local/nginx/ [[email protected] software]# chmod 755 /usr/local/nginx/perl-fcgi.pl [[email protected] software]# cd /usr/local/nginx/ [[email protected] nginx]# chmod 755 start_perl_cgi.sh
编写start_perl_cgi.sh脚本
[[email protected] nginx]# ./start_perl_cgi.sh start
start perl-fcgi done
[[email protected] nginx]# ll /usr/local/nginx/logs/perl-fcgi.sock
srwxr-xr-x 1 www www 0 Apr 18 11:02 /usr/local/nginx/logs/perl-fcgi.sock
[[email protected] nginx]# echo "/bin/sh /usr/local/nginx/start_perl_cgi.sh start" >>/etc/rc.local
安装Nagios：
[[email protected] software]# yum -y install libgd2-noxpm libgd2-noxpm-dev [[email protected] software]# yum -y install php-gd [[email protected] software]# groupadd nagcmd [[email protected] software]# useradd -G nagcmd nagios [[email protected] software]# usermod -G nagcmd www [[email protected] software]# tar -zxvf nagios-3.3.1.tar.gz &>/dev/null [[email protected] software]# cd nagios [[email protected] nagios]# ./configure --with-command-group=nagcmd --prefix=/usr/local/nagios --with-gd-lib=/usr/lib --with-gd-nc=/usr/include [[email protected] nagios]# make all &&make install &&make install-init &&make install-config &&make install-commandmode [[email protected] nagios]# yum -y install httpd-tools [[email protected] nagios]# cd /usr/local/nagios/etc/ [[email protected] etc]# htpasswd -cm htpasswd.users yfshare [[email protected] etc]# sed -i '/authorized\_for\_/s/nagiosadmin/&\,yfshare/g' cgi.cfg [[email protected] etc]# cd /usr/local/nginx/conf/ [[email protected] etc]# mkdir /usr/local/nagios/logs
[[email protected] etc]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg |grep ^Total
Total Warnings: 0
Total Errors: 0
[[email protected] etc]# /etc/init.d/nagios start
Starting nagios: done.
[[email protected] etc]# chkconfig --add nagios [[email protected] etc]# chkconfig nagios on
也可通过访问http://www.4webhelp.net/us/password.php生成htpasswd.users
[[email protected] etc]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.
[[email protected] etc]#
[[email protected] conf]# /etc/init.d/nginx restart
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Stopping nginx: [ OK ]
Starting nginx: [ OK ]
[[email protected] conf]#
安装Nagios-plugin：
[[email protected] software]# tar -zxvf nagios-plugins-1.4.15.tar.gz &>/dev/null [[email protected] software]# cd nagios-plugins-1.4.15 [[email protected] nagios-plugins-1.4.15]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-perl-modules [[email protected] nagios-plugins-1.4.15]# make &&make install [[email protected] software]# ls /usr/local/nagios/libexec/|wc -l 58 [[email protected] software]#
安装NRPE：
[[email protected] software]# yum -y install openssl openssl-devel [[email protected] software]# tar -zxvf nrpe-2.13.tar.gz &>/dev/null [[email protected] software]# cd nrpe-2.13 [[email protected] nrpe-2.13]# ./configure [[email protected] nrpe-2.13]# make all &&make install-plugin &&make install-daemon &&make install-daemon-config [[email protected] nrpe-2.13]# cd /usr/local/nagios/etc/ [[email protected] etc]# sed -i '/allowed_host/s/127.0.0.1/&,192.168.10.99/g' nrpe.cfg [[email protected] etc]# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d [[email protected] etc]# echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d" >> /etc/rc.local
[[email protected] etc]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.13
[[email protected] etc]#
访问:http://192.168.10.99/nagios
但是，打开页面时，其他选项卡都是显示的502 Bad Gateway
[[email protected] ~]# chown nagios:nagcmd /usr/local/nagios/ -R
[[email protected] ~]# chown www:nagcmd /usr/local/nginx/ -R
[[email protected] ~]# cd /usr/local/nginx/
[[email protected] nginx]# ./start_perl_cgi.sh start
ERROR PID file /usr/local/nginx/logs/perl-fcgi.pid already exists
start perl-fcgi done
[[email protected] nginx]#
因为perl-fcgi进程意外中断，但是进程未退出变成了孤儿进程，所以就变成这样了
修改下脚本start_perl_cgi.sh，把这个脚本写成服务或者加入开机脚本（关闭sudo的tty）
[[email protected] nginx]# ./start_perl_cgi.sh start
start perl-fcgi done
[[email protected] nginx]#
[[email protected] nginx]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.
[[email protected] nginx]# /etc/init.d/nginx restart
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Stopping nginx: [ OK ]
Starting nginx: [ OK ]
[[email protected] nginx]#
OK，在Nginx上安装Nagios成功
如果出现上面的问题，解决方法：
[[email protected] ~]# sed -i '/use_authentication/s/1/0/g' /usr/local/nagios/etc/cgi.cfg
[[email protected] ~]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.
[[email protected] ~]# /etc/init.d/nginx restart
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Stopping nginx: [ OK ]
Starting nginx: [ OK ]
[[email protected] ~]#
访问http://192.168.10.99/nagios/
OK，Successful
