Cacti+Nagios监控系统（一）：准备工作
一、系统环境1、设置yum源 （1）使用本地源 挂载光驱ISO文件 确认路径/media/CentOS_6.5_Final/ cd /etc/yum.repos.d mv CentOS-Base.repo CentOS-Base.repo.bak vi CentOS-Base.repo name=Basebaseurl=file:///media/CentOS_6.5_Final/
gpgcheck=0 #(1检测 0不检测)
enabled=1 #(1启动 0不启动) （2）使用163的源 cd /etc/yum.repos.d wget http://mirrors.163.com/.help/CentOS6-Base-163.repo mv CentOS-Base.repo CentOS-Base.repo.bak2 mv CentOS6-Base-163.repo CentOS-Base.repo （3）更新列表 yum clean all yum list2、安装图形界面 查看是否安装了桌面环境的组件 yum grouplist | more yum groupinstall -y "Desktop" "Desktop Platform" "Desktop Platform Development" "Fonts" "General Purpose Desktop" "Graphical Administration Tools" "Graphics Creation Tools" "Input Methods" "X Window System" "Chinese Support " "Internet Browser" vi /etc/inittab 修改启级别为5 reboot重新启动3、设置并启用网卡 ifconfig -a vi /etc/sysconfig/network-scripts/ifcfg-eth0 设置网卡静态IP地址，自动启动为ON ifup eth0 echo "nameserver 202.101.224.68">> /etc/resolv.conf4、配置VNC远程桌面 yum install -y tigervnc-server vncserver :1 密码123456 vi /root/.vnc/xstartupunset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
#twm&
gnome-session vncserver -kill :1 vncserver :1 设置自动启动 vi /etc/sysconfig/vncserversVNCSERVERS="1:user1"
VNCSERVERARGS="-geometry 800x600 -alwaysshared " chkconfig vncserver on5、关闭selinux vi /etc/selinux/config SELINUX=disabled 重启服务器即可 不想重启可执行setenforce 06、ntpupdate同步时间 crontab -e 10 * * * * /usr/sbin/ntpdate -s 65.55.56.206 service crond restart ntpdate 65.55.56.2067、setup自启动项 配置系统自动启动项 httpd mysqld snmpd nagios vncserver network8、FTP文件传输 yum install -y vsftpd vi /etc/vsftpd/vsftpd.confanonymous_enable=NO#禁止匿名访问
userlist_deny=NO #（手动添加）使用FTP用户表 useradd ywzhou passwd ywzhou 123456 vi /etc/vsftpd/user_list ywzhou /etc/init.d/vsftpd start chkconfig vsftpd on9、防火墙 iptables -I INPUT -p tcp --dports 21,80,5901 -j ACCEPT service iptables save 或者 vi /etc/sysconfig/iptables-A INPUT -p tcp --dport 21 -j ACCEPT-A INPUT -p tcp --dport 80 -j ACCEPT-A INPUT -p tcp --dport 5901 -j ACCEPT service iptables restart二、编译环境
1、安装gcc
yum install gcc
2、安装glibc
yum install glibc glibc-common
3、安装gd
yum install gd gd-devel
4、安装pcap
yum install libtool libpcap libpcap-devel gdbm gdbm-devel zlib zlib-devel
注意：使用本地YUM源安装时，个别包没有，需要更换为163源在线安装。
二、LAMP环境
1、安装apache
yum install -y httpd
vi /etc/httpd/conf/httpd.conf
DirectoryIndexindex.php index.html
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
service httpd start
chkconfig httpd on
vi /etc/sysconfig/iptables
-A INPUT -p tcp --dport 80 -j ACCEPT
service iptables restart
2、安装php
yum install -y php php-mysql php-devel php-snmp php-gd
vim /var/www/html/index.php
<?php phpinfo(); ?>
http://localhost
3、安装mysql
yum install -y mysql mysql-server mysql-devel
service mysqld start
chkconfig mysqld on
mysqladmin -u root password '123456'
断电导致mysqld无法启动问题:
service mysql restart
Another MySQL daemon already running with the same unix socket
mv /var/lib/mysql/mysql.sock/var/lib/mysql/mysql.sock.bak
service mysqld restart
