1   Nginx

Nginx编译安装

 

问题

./configure: error: the HTTP rewrite module requires the PCRE library.

You can either disable the module by using --without-http_rewrite_module

option, or install the PCRE library into the system, or build the PCRE library

statically from the source with nginx by using --with-pcre= option.

解决办法

# yum install pcre-devel

 

修改nginx.conf配置文件

 

location ~ \.php$ {        

    root           /usr/local/cacti/;

    fastcgi_pass   127.0.0.1:9000;

    fastcgi_index  index.php;

    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

    include        fastcgi.conf;

}

location ~* ^.+\.(css|js|ico|gif|jpg|jpeg|png|html|htm)$ {

    root /usr/local/cacti/;

    index  index.html index.htm;

}

 

nginx启动

./nginx

其他参数命令参考

nginx -hnginx version: nginx/0.8.54

Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]

 

Options:

  -?,-h         : this help

  -v            : show version and exit

  -V            : show version and configure options then exit

  -t            : test configuration and exit

  -q            : suppress non-error messages during configuration testing

  -s signal     : send signal to a master process: stop, quit, reopen, reload

  -p prefix     : set prefix path (default: /home/q/nginx/)

  -c filename   : set configuration file (default: conf/nginx.conf)

  -g directives : set global directives out of configuration file

2   MySQL

已经安装好,具体情况,查看相关的MySQL安装文档

安装目录/home/q/mysql

3   PHP

php5.3版本,内置了fpm功能模块

下载

wget

解压,编译

tar zxvf php-5.3.6.tar.gz

cd php-5.3.6

./configure --prefix=/usr/local/php --enable-sockets --enable-fpm --with-mysql=/home/q/mysql

make

make install

 

复制一个php.ini文件

cp ../php-5.3.6/php.ini-production  /usr/local/php/lib/

添加时区的参数,设置cacti的时候会用到

date.timezone = "Asia/Chongqing"

 

修改/usr/local/php/etc/php-fpm.conf配置文件,将以下参数取消注释

pid = run/php-fpm.pid

error_log = log/php-fpm.log

log_level = notice

pm.max_children = 50

pm.start_servers = 20

pm.min_spare_servers = 5

pm.max_spare_servers = 35

 

启动php-fpm服务(端口9000)

/usr/local/php/sbin/php-fpm

 

[可选]验证php的功能,编写一个php的测试页面,内容如下

phpinfo();

?>

4   Cacti 4.1     rrdtool,snmp

安装rrdtool,这个工具是用来绘图的,先下载一个yum

wget

yum install rrdtool

 

# vim /etc/snmp/snmpd.conf ,注意修改团体名

 

4.2     cacti

yum需要的组件包

yum install net-snmp-devel net-snmp-utils openssl-devel

 

wget

tar zxvf cacti-0.8.7g.tar.gz

cd cacti-0.8.7g

下载并安装补丁

wget

wget

wget

wget

wget

wget

wget

patch -p1 -N < data_source_deactivate.patch

patch -p1 -N < graph_list_view.patch

patch -p1 -N < html_output.patch

patch -p1 -N < ldap_group_authenication.patch

patch -p1 -N < script_server_command_line_parse.patch

patch -p1 -N < ping.patch

patch -p1 -N < poller_interval.patch

移动目录

mv /opt/cacti-0.8.7g /var/www/cacti

 

4.3     spine

wget

tar zxvf cacti-spine-0.8.7g.tar.gz

cd cacti-spine-0.8.7g

下载并安装补丁

wget

patch -p1 -N < unified_issues.patch

编译

./configure --with-mysql=/home/q/mysql

make

make install

 

测试

修改连接MySQL的配置文件/usr/local/spine/etc/spine.conf

启动命令/usr/local/spine/bin/spine

4.4     导入数据

mysql> create database cacti;

mysql> grant all privileges on cacti.* to 'cacti'@'localhost' identified by 'password***';

mysql> use cacti;

mysql> source cacti.sql

mysql> flush privileges;

mysql> exit

 

4.5     配置文件

vim /usr/local/cacti/include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "localhost";

$database_username = "cacti";

$database_password = " password***";

$database_port = "3306";

 

定制任务,以root用户,每五分钟收集一次信息

crontab –e

 

*/5 * * * * /usr/local/php/bin/php /home/q/www/cacti/poller.php >/dev/null 2>&1

 

 

4.6     cacti初始化

url地址

 

点击Next

下个页面的各个工具路径,需要根据具体的安装路径指定.

......

 

4.7     spine的设置

Setting----paths----“Spine Poller File Path”|选中”Structured RRA Path (/host_id/local_data_id.rrd)”

4.8     导入模板,添加帐号

导出l-dbmonitor.ops.cn1cacti模板(包括* Linux GenericX MySQL Server HT)

l-dbmonitor.ops.cn2中导入(连接MySQL的密码也会包含在内)

检测脚本ss_get_mysql_stats.php,也要用cn1,这个添加了MySQL多端口监控的支持

 

在各个MySQL服务器创建监控帐号

mysql -uroot -p' password***' -e "GRANT PROCESS, SUPER ON *.* TO 'monitor'@'192.168.0.1' IDENTIFIED BY ' password***';FLUSH PRIVILEGES;"

 

 

参考

Linux主机模板(可选)

wget

 

MySQL模板

5   FAQ

./spine: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory

[root@l-dbmonitor bin]# find / -name  libmysqlclient.so.18

/home/q/mysql-5.5.14/libmysql/libmysqlclient.so.18

/home/q/mysql/lib/libmysqlclient.so.18

[root@l-dbmonitor bin]# ln -s /home/q/mysql/lib/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18

 

 

MYSQL: Connection Failed: Error:'2002', Message:'Can't connect to local MySQL server through socket '/home/q/mysql/data/mysql.sock' (2)'

修改了mysql

socket           = /home/q/mysql/data/mysql.sock

 

 

如果MySQL5.5,需要将cacti.sql中的TYPE=MyISAM,改成ENGINE=MyISAM

有一个补丁文件cacti.sql-MySQL-5.5.9.patch,可以改cacti.sql文件

 

 

configure: error: xml2-config not found. Please check your libxml2 installation.

解决

yum install libxml2 libxml2-devel
