1、基础环境安装（系统最小安装）
yum install gcc glibc glibc-common gd gd-devel httpd
2、 nagios和 nagios-plus的安装
/usr/sbin/useradd nagios /usr/sbin/groupadd nagcmd /usr/sbin/usermod -G nagcmd nagios /usr/sbin/usermod -G nagcmd apache tar -jxvf nagios-cn-3.2.3.tar.bz2 cd nagios-cn-3.2.3 ./configure --with-group=nagios --with-user=nagios --with-command-group=nagcmd --with-gd-lib=/usr/lib --with -gd-inc=/usr/include make all make install make install-init make install-commandmode make install-config make install-webconf htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin ##创建web登录用户名和密码 chown -R nagios.nagios /usr/local/nagios/etc/htpasswd.users tar -zxvf nagios-plugins-1.4.16.tar.gz cd nagios-plus-1.4.16 ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-gourp=nagios make&&make install
PS:当安装nagios-plugins-1.4.16时候报错如下：
ps/check_http.Tpo -c -o check_http.o check_http.c check_http.c: In function ‘process_arguments’: check_http.c:312: error: ‘ssl_version’ undeclared (first use in this function) check_http.c:312: error: (Each undeclared identifier is reported only once check_http.c:312: error: for each function it appears in.) make[2]: *** [check_http.o] Error 1 make[2]: Leaving directory `/data/nagios-plugins-1.4.16/plugins' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/data/nagios-plugins-1.4.16' make: *** [all] Error 2
解决办法：
1、yum -y install openssl openssl-devel 2、重新configure
3、配置文件修改
