CentOS 7 LNMP环境搭建Zabbix3.0

概述：在CentOS 7 64位操作系统环境下搭建LNMP（Linux+Nginx+MySQL+PHP）来运行Zabbix监控程序

预先安装：

yum install -y autoconf make automake imake cmake gcc gcc-c++ libaio libaio-devel bzr bison expat-devel libtool ncurses5-devel gd-devel libjpeg-devel libpng-devel libxml2-devel bzip2-devel libcurl-devel
yum install pcre*
yum install openssl*

yum install epel-release  
yum clean all  
yum repolist

第一部分：安装MySQL 5.7

1. 首先下载MySQL Yum repository，CentOS 7对应的下载链接如下

wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

2. 下载完成之后安装下载好的rpm文件

yum localinstall mysql57-community-release-el7-7.noarch.rpm

3.  安装完成之后验证MySQL YUM repository

yum repolist enabled | grep "mysql.*-community.*"

如下图所示，表示验证成功：

4. 安装最新版的MySQL

yum install mysql-community-server

5. 安装完成之后启动并查看MySQL状态：

service mysqld start
service mysqld status

6. 手动验证MySQL安装的版本：

mysql --version

7. 安装MySQL 5.7之后，MySQL会生成一个随机密码在/var/log/mysqld.log文件中，使用如下命令查看密码：

grep 'temporary password' /var/log/mysqld.log

8. 记录密码之后，运行 mysql_secure_installation初始化MySQL，初始化过程中会提示输入随机密码

mysql_secure_installation

9. 使用新设置的密码连接MySQL：

mysql -u root -p

10. 至此，MySQL 5.7安装完成。

第二部门  安装Nginx

1. 首先下载Nginx的最新稳定版，本示例使用的版本是1.10，下载之后解压压缩包：

tar zxvf nginx-1.10.1.tar.gz

2. 进入解压之后的Nginx目录，运行configure

./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-pcre

3. 编译安装

make
make install

4. 测试Nginx

/usr/local/nginx/sbin/nginx -t

第三部分  安装PHP

1. 首先安装开发软件包：

yum -y groupinstall  "Development Tools"

2. 下载PHP最新稳定版，解压安装包，本示例使用的是PHP 5.6.25

tar -zxvf php-5.6.25.tar.gz

3. 切换到PHP目录，运行configure：

./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 -with-png-dir=/usr/local -with-freetype-dir=/usr/local -enable-gd-native-ttf -with-iconv-dir=/usr/local -enable-mbstring -enable-calendar -with-gettext -with-libxml-dir=/usr/local -with-zlib -with-pdo-mysql=mysqlnd -with-mysqli=mysqlnd -with-mysql=mysqlnd -enable-dom -enable-xml -enable-fpm -with-libdir=lib64 -enable-bcmath

4. 

make
make install

5. 复制安装包中的php.ini-production到 /usr/local/php/etc/php.ini

cp php.ini-production /usr/local/php/etc/php.ini

cp /usr/local/php/etc/php-fpm.conf.default.conf  php-fpm.conf

6. 测试PHP安装是否成功。

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

7. 测试成功之后启动PHP

cp /usr/local/src/php-5.3.27/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
service php-fpm start
 

8. 添加到开机启动

chkconfig php-fpm on

9. 检查是否启动

ps aux |grep php-fpm
netstat -ant |grep 9000

第四部分 配置Nginx运行PHP

1. 修改Nginx配置文件如下

vim /usr/local/nginx/conf/nginx.conf

 

user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;

events
{
    use epoll;
    worker_connections 6000;
}

http
{
    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 3526;
    server_names_hash_max_size 4096;
    log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
    '$host "$request_uri" $status'
    '"$http_referer" "$http_user_agent"';
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 30;
    client_header_timeout 3m;
    client_body_timeout 3m;
    send_timeout 3m;
    connection_pool_size 256;
    client_header_buffer_size 1k;
    large_client_header_buffers 8 4k;
    request_pool_size 4k;
    output_buffers 4 32k;
    postpone_output 1460;
    client_max_body_size 10m;
    client_body_buffer_size 256k;
    client_body_temp_path /usr/local/nginx/client_body_temp;
    proxy_temp_path /usr/local/nginx/proxy_temp;
    fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
    fastcgi_intercept_errors on;
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 8k;
    gzip_comp_level 5;
    gzip_http_version 1.1;
    gzip_types text/plain application/x-javascript text/css text/htm application/xml;

server
{
    listen 80;
    server_name localhost;
    index index.html index.htm index.php;
    root /usr/local/nginx/html;

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass 127.0.0.1：9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
    }

}

}

2. 创建PHP测试网页

vim /usr/local/nginx/html/test.php

<?php
    phpinfo();
?>

3. 在浏览器中输入localhost/test.php，测试php页面

4. 配置PHP参数，Zabbix的硬件要求

vim /usr/local/php/etc/php.ini

max_execution_time = 300
max_input_time = 300
memory_limit = 128M
post_max_size = 16M
upload_max_filesize = 2M
date.timezone = Asia/Shanghai
always_populate_raw_post_data = -1

5. 重启PHP

service php-pfm stop
service php-pfm start

第五部分 安装Zabbix

1. 下载安装zabbix的YUM源

rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

2. 安装Zabbix

yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-get

3. 安装之后进入MySQL数据库，创建Zabbix数据库

create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to 'zabbix'@'%' identified by 'zabbixpass';
flush privileges;

4. 导入Zabbix到数据库

cd /usr/share/doc/zabbix-server-mysql-3.0.1/
zcat create.sql.gz |mysql -uroot -ppass zabbix

5. 配置zabbix用户

groupadd zabbix
useradd -g zabbix -s /bin/false zabbix

6. 配置Zabbix服务器端

vim /etc/zabbix/zabbix_server.conf

DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbixpass

cd /usr/share/
cp -r zabbix /usr/local/nginx/html
chown -R zabbix:zabbix /etc/zabbix
chown -R zabbix:zabbix /usr/share/zabbix
chown -R zabbix:zabbix /usr/lib/zabbix

7. Zabbix加入开机启动并启动

systemctl enable zabbix-server
systemctl start zabbix-server

8. 在浏览器中测试Zabbix

常见错误排除

问题，运行Zabbix时出现“

FastCGI sent in stderr: "PHP message: PHP Warning:  require_once(/etc/zabbix/web/maintenance.inc.php):   failed to open stream: Permission denied in /app/nginx/html/zabbix/include/classes/core/ZBase.php on line 292

PHP message: PHP Fatal error:  require_once(): Failed opening required '/etc/zabbix/web/mainte

”

解决方法：

chmod -R 755 /etc/zabbix/web
