The establishment of cacti Cacti on nginx is a set of network traffic monitoring graphical analysis tools developed based on PHP, MySQL, SNMP and RRDTool www.2cto.com Cacti and Nagios are now using a lot of network monitoring software, the difference between the two monitoring software should be said to be the difference in focus. Cacti focuses on visual data monitoring and is easy to generate images. it is suitable for monitoring network Traffic, cpu usage, and hard disk usage. While Nagios focuses more on host and service monitoring, and has powerful alarm sending functions. By combining the two, the alarm mechanism can be efficient and timely, and various data can be easily viewed. 1. set up cacti 1 on LNMP (linux + nginx + mysql + php. modify selinux vim/etc/selinux/config to selinux = disabled disable firewall service iptables stop chkconfig iptables off restart to bring selinux into effect reboot install compilation tool and library file www.2cto.com for I in 'rpm- q make apr * autoconf automake curl-devel gcc-c ++ zlib-devel openssl-devel pcre-devel gd kernel keyutils patch perl kernel-headers compat * mpfr cpp glibc golibmp libstdc ++-devel ppl clo Og-ppl keyutils-libs-devel libcom_err-devel libsepol-devel libselinux-devel krb5-devel zlib-devel libXpm * freetype libjpeg * libpng * php-common php-gd ncurses * libtool * libxml2 libxml2-devel patch | grep not installed '| awk' {print $2 }''; do yum-y install $ I; done install libmcrypt cd/usr/local/srctar zxvf libmcrypt-2.5.7.tar.gzcd libmcrypt-2.5.7. /configuremake & make install cmake cd/usr/local/src Tar zxvf cmake-2.8.7.tar.gzcd cmake-2.8.7. /configuremake & make install pcre cd/usr/local/srcmkdir/usr/local/pcre # Create installation directory tar zxvf pcre-8.30.tar.gzcd pcre-8.30. /configure -- prefix =/usr/local/pcremake & make install mysql groupadd mysql # Add mysql group useradd-g mysql-s/bin/false # create mysql and add it to mysql group, mysql is not allowed to log on to mkdir-p/data/mysql # create the MySQL database storage directory chown-R mysql: mysql/data/mysql # set the MySQL database directory permission m Kdir-p/usr/local/mysql # create the MySQL installation directory cd/usr/local/srctar zxvf mysql-5.5.21.tar.gzcd mysql-5.5.21cmake. -DCMAKE_INSTALL_PREFIX =/usr/local/mysql-DMYSQL_DATADIR =/data/mysql-DSYSCONFDIR =/etc # configure makemake installcd/usr/local/mysqlcp. /support-files/my-huge.cnf/etc/my. cnf # Copy the configuration file vim/etc/my. cnf # Add datadir =/data/mysql # to the MySQL database path in [mysqld. /scripts/mysql_install_db -- user = mysql # generate mysql system database cp. /Support-files/mysql. server/etc/rc. d/init. d/mysqld # Add Mysql to the system and start chmod 755/etc/init. d/mysqld # Add execution permission chkconfig mysqld on # add to start vim/etc/rc at startup. d/init. d/mysqld # Edit basedir =/usr/local/mysql # MySQL program installation path datadir =/data/mysql # MySQl database storage directory service mysqld start # start vim/etc/profile # add the mysql service to the system environment variable: add the following line of export PATH = $ PATH at the end: /usr/local/mysql/bin to make the environment variable take effect immediately. the following two lines under source/etc/profile link the myslq library file to the default system location and compile the class Software such as PHP may not specify the mysql library file address.
