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 3.4 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
5. 防火墙开放80端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
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/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
2. 安装Zabbix
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-get zabbix-agent
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-3.41/ zcat create.sql.gz | mysql -u root -p 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
