# tar zxf nginx-1.8.1.tar.gz
# ./configure --prefix=/usr/local/nginx \
--with-http_ssl_module --with-http_spdy_module \

server {
listen 80;
server_name www.apicloud.com;
access_log /data/logs/nginx/www.xxx.com.access.log main;
index index.php index.html index.html;
root /data/site/www.xxx.com;
location /
{
try_files $uri $uri/ /index.php?$args;
}
location ~ .*\.(php)?$
{
expires -1s;
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include fastcgi_params;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass 127.0.0.1:9000;
}
}
# /usr/local/nginx/sbin/nginx
2. 安装php
# wget http://cn2.php.net/distributions/php-5.6.20.tar.gz
# tar zxf php-5.6.20.tar.gz
# ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-bz2 --with-curl \
--enable-ftp --enable-sockets --disable-ipv6 --with-gd --with-jpeg-dir=/usr/local \

# make && make install
# cp php.ini-production /usr/local/php/etc/php.ini
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
# vim /usr/local/php/etc/php.ini
max_execution_time = 300
memory_limit = 128M
post_max_size = 16M
upload_max_filesize = 2M
max_input_time = 300
date.timezone = PRC
# /usr/local/php/sbin/php-fpm
重启nginx
3. 安装mysql
# wget http://120.52.73.48/jaist.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
# mkdir /usr/local/boost
# mv boost_1_59_0.tar.gz /usr/local/boost/boost_1_59_0.tar.gz
# wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.15.tar.gz
# groupadd mysql
# useradd -r -g mysql mysql
# tar zxf mysql-5.7.15.tar.gz
# cd mysql-5.7.15
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci - DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/data/mysqldb -DMYSQL_TCP_PORT=3306 - DWITH_BOOST=/usr/local/boost/boost_1_59_0.tar.gz
# make && make install
# chown -R mysql:mysql /usr/local/mysql/*
# cd /usr/local/mysql
# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysqldb(生成新的随机密码) mFR7jRa-9r4/
# cp -f /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
# cp -f /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
# vim /etc/profile
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
# export PATH
# source /etc/profile
# chmod o=rwx /usr/local/mysql
# service mysqld start
# chkconfig --level 2345 mysqld on
# mysql -u root -p (随机密码)
mysql> SET PASSWORD = PASSWORD(‘123456‘);
mysql> flush privileges;
4. 安装zabbix
# wget http://jaist.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/2.4.8/zabbix-2.4.8.tar.gz
# tar zxf zabbix-3.0.3.tar.gz
# cd zabbix-3.0.3
# ./configure --prefix=/usr/local/zabbix/ --enable-server \
--enable-agent --with-mysql --with-net-snmp --with-libcurl --with-libxml2 --enable-proxy --enable-snmp --with-mbstring
# make && make install
# cp -rp frontends/php/* /data/site/www.apicloud.com/zabbix
# cp -f /usr/local/src/zabbix-3.0.3/misc/init.d/fedora/core5/* /etc/init.d/
# vim /etc/init.d/zabbix_server
ZABBIX_BIN="/usr/local/zabbix/sbin/zabbix_server"
# vim /etc/init.d/zabbix_agentd
ZABBIX_BIN="/usr/local/zabbix/sbin/zabbix_agentd"
# chkconfig --add zabbix_server
# chkconfig --add zabbix_agentd
# chkconfig zabbix_server on
# chkconfig zabbix_agentd on
更改zabbix字体:
复制C:\Windows\Fonts(楷体)到/data/site/www.apicloud.com/zabbix/fonts
# cd /data/site/www.apicloud.com/zabbix
# sed -i ‘s/DejaVuSans/simkai/g‘ ./include/defines.inc.php
# ln -s /usr/local/mysql/lib/libmysqlclient.so.20 /lib64/
# groupadd zabbix && useradd -r -g zabbix -s /etc/nologin zabbix
初始化数据库:
mysql> create database zabbix default charset utf8;
# mysql -uroot -p zabbix < database/mysql/schema.sql
# mysql -uroot -p zabbix < database/mysql/images.sql
# mysql -uroot -p zabbix < database/mysql/data.sql
# vim /usr/local/zabbix/etc/zabbix_server.conf
DBUser=root
DBPassword=123456
# service zabbix_server start
修改zabbix前端安装文件:
# vim /data/site/www.apicloud.com/zabbix/include/classes/setup/CFrontendSetup.php
添加$current = -1;
public function checkPhpAlwaysPopulateRawPostData() {
$current = ini_get(‘always_populate_raw_post_data‘);
$current = -1;
网页安装zabbix-server:
http://ip/zabbix
Database host 127.0.0.1
User root
Password 123456
1.Download the configuration file
2.Save it as "/data/site/www.apicloud.com/zabbix/conf/zabbix.conf.php"
zabbix默认管理账号
user:admin
password:zabbix
如果账号密码错误,需要自行设置密码:
echo -n XXXXX | openssl md5
mysql -uroot -p
use zabbix;
update users set passwd=‘XXXXXXXXXXXXXXXXXXXXXXXXXXXX‘ where userid = ‘1‘;
5.zabbix客户端配置
# groupadd zabbix && useradd -r -g zabbix -s /etc/nologin zabbix
# tar zxf zabbix-2.4.8.tar.gz
# cd zabbix-2.4.8
# ./configure --prefix=/usr/local/zabbix --enable-agent
# make && make install
# vim /usr/local/zabbix/etc/zabbix_agentd.conf
Server=10.124.151.248 (zabbix_server IP) (被动)
ServerActive=10.124.151.248 (zabbix_server IP) (主动)
Hostname=agent-1 (独立主机名)
# cp -f /usr/local/src/zabbix-2.4.8/misc/init.d/fedora/core5/zabbix_agentd /etc/init.d/
# vim /etc/init.d/zabbix_agentd
ZABBIX_BIN="/usr/local/zabbix/sbin/zabbix_agentd"
# chkconfig --add zabbix_agentd
# chkconfig zabbix_agentd on
# service zabbix_agentd start
iptables -I INPUT -p tcp --dport 10050 -j ACCEPT
service iptables save
注:如果客户端过多可开启自动发现,自动添加到zabbix主机;
6.zabbix的使用
1.主机的添加
配置 —> 主机 —> 创建主机 —> 主机名称(Hostname) —> 可见主机名(随意) —> 群组 —> IP地址 —> 主机模板 —> 搜索模板 —> 添加 —> 添加
2.监控项
一种是链接模板,如果有特殊的需求可以选择手动添加监控项;
第一种:配置 —> 主机 —> 模板 —> 添加 ;
第二种:配置 —> 主机 —> 监控项 —> 创建监控项 —> 监控名称 —> 键值(手动在客户端配置文件里面添加,具体步骤在下面) —> 信息类型 —> 数据类型 —> 间隔秒数 —> 时间间隔(可选) —> 启用
客户端创建键值:
# vim /usr/local/zabbix/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UserParameter=mongodb.node,ps -ef|grep [n]ode|wc -l
格式:UserParameter= name.item, + command
注:自定义监控可能出现first network error, wait for 15 seconds,可更改server和agentd的Timeout=30即可。
3.监控报警
zabbix监控报警流程:zabbix通过监控项监控数据 —> 触发器 —> 动作 —> 用户。
触发器达到触发器预设值或者宕机时就产生动作,根据动作发邮件或者短信,最后发送给指定的用户。
# yum install postfix
# service postfix start
# chkconfig postfix on
邮件报警设置步骤:管理 —> 报警媒介类型 —> 管理 —> 用户 —> Admin —> 报警媒介 —> 添加 —> 配置 —> 动作 —> 创建动作 —> 操作 —> 添加
7.zabbix proxy配置(需要安装mysql)
# groupadd zabbix && useradd -r -g zabbix -s /etc/nologin zabbix
# tar zxf zabbix-2.4.8tar.gz
# cd zabbix-2.4.8
# ./configure --prefix=/usr/local/zabbix --enable-proxy --with-mysql --with-net-snmp --with-libcurl --enable-agent
# make && make install
mysql> create database zabbix_proxy default charset utf8;
# mysql -uroot -p zabbix_proxy < database/mysql/schema.sql
# service mysqld start
# vim /usr/local/zabbix/etc/zabbix_proxy.conf
ProxyMode=0
Server=123.56.22.xx(zabbix_server IP)
DBName=zabbix_proxy
DBUser=zabbixproxy
DBPassword=zabbixproxy
# /usr/local/zabbix/sbin/zabbix_proxy
服务端设置
Server=(proxy IP)
ServerActive=(proxy IP)
Hostname=xxxx (独立主机名)
8.zabbix 2.4.8升级3.X.X
1.备份zabbix前端静态文件
2.备份zabbix安装目录
3.备份整个mysql或者zabbix库
4.上传源码包,并删除原安装目录,编译安装
