LNMP+zabbix监控平台搭建
前言
由于某个项目需要新搭建zabbix监控平台。于是就抽时间总结了zabbix搭建的流程及排错的详细流程。由于每个人的生产环境的差异，本文适用于参考。
实际上，使用yum安装配置LAMP+zabbix更加的方便，快捷。但是，为了便于管理，此处使用的是源码安装。
系统：centos7.6
安装方式：源码安装
nginx版本：1.17.1
mysql版本：5.6.44
php版本：7.3.7
zabbix-server版本：4.2.4
Nginx源码安装
【1】安装依赖包
为了避免后期的问题，安装了大量的依赖包，其中可能有某些并不必要
yum install -y perl-ExtUtils-Embed readline-devel zlib-devel pam-devel libxml2-devel libxslt-devel openldap-devel python-devel gcc-c++ openssl-devel cmakepcre-develnanowget gcc gcc-c++ ncurses-devel perl pcre pcre-devel openssl openssl-devel fping
【2】下载并安装源码包
<1>创建nginx用户（为了安全，可禁止其登录）
useradd nginx -s /sbin/nologin
<2>从Nginx官网下载Nginx源码包
（ /apk/package为创建的安装包统一存放位置）
wget http://nginx.org/download/nginx-1.17.1.tar.gz
tar xf nginx-1.17.1.tar.gz -C /apk/package
cd /apk/package/nginx-1.17.1
<3>编译安装
(/apk/install/nginx-1.17.1为安装目录)
注意编译参数（–prefix指定安装软件目录）：
./configure --prefix=/apk/install/nginx-1.17.1 --with-http_stub_status_module --without-http_auth_basic_module --without-http_autoindex_module --without-http_browser_module --without-http_geo_module --without-http_limit_req_module --without-http_limit_conn_module --without-http_map_module --without-http_memcached_module --without-http_scgi_module --without-http_split_clients_module --without-http_userid_module --without-http_uwsgi_module --without-mail_imap_module --without-mail_pop3_module --without-mail_smtp_module --without-poll_module --without-select_module --with-stream --add-module=/apk/install/nginx-mod/mode --add-module=/apk/install/nginx-mod/nginx-module
下列为此次使用的编译参数：
./configure --prefix=/apk/install/nginx-1.17.1 --with-http_stub_status_module --without-http_auth_basic_module --without-http_autoindex_module --without-http_browser_module --without-http_geo_module --without-http_limit_req_module --without-http_limit_conn_module --without-http_map_module --without-http_memcached_module --without-http_scgi_module --without-http_split_clients_module --without-http_userid_module --without-http_uwsgi_module --without-mail_imap_module --without-mail_pop3_module --without-mail_smtp_module --without-poll_module --without-select_module --with-stream --with-http_ssl_module --with-pcre
make -j4
make install
–add-module为指定第三方模块的安装目录，如没安装第三方模块，可不配置，否则编译时会报如下错误：
Nginx配置zabbix
注意：/apk/install/nginx-1.17.1在此处为nignx编译时，指定的软件安装目录。修改配置文件要从自己指定的安装目录中找。
【1】配置启动方式
<1>做软链接或配置环境变量，使nginx命令可被直接使用
ln -s /apk/install/nginx-1.17.1/sbin/nginx /usr/sbin/nginx
<2>测试nginx配置文件是否有问题
nginx -t
<3>启动nginx
nginx
【2】配置nginx的zabbix目录
<1>创建zabbix的web文件存放目录
mkdir /apk/data/web/zabbix -pv
<2>nginx配置文件如下：
cat /apk/install/nginx-1.17.1/conf/nginx.conf

【3】mysql初始化
<1>mysql初始化
（根据需求选择合适的命令。如报错，需修改参数后，再次初始化）
/apk/install/mysql-5.6.44/script/mysql_install_db --user=mysql --basedir=/apk/install/mysql/mysql-5.6.44 --datadir=/apk/data/mysql_3306/data --pid-file=/apk/data/mysql_3306/data/mysql.pid --socket=/tmp/mysql_3306.sock --port=3306
or
/apk/install/mysql/mysql-5.6.44/script/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql
如初始化有报错，请先检查一下配置文件中的参数。修改后仍报错，可在上方的参数后添加 --no-defaults
<2>启动mysql
/etc/init.d/mysql_3306 start
如报pid相关错误，可先检查mysql的配置文件参数后，查看下列链接尝试解决：
https://blog.csdn.net/GX_1_11_real/article/details/93010284
<3>设置账号和密码
mysqladmin -u root -p password 你的密码
PHP源码安装
【1】安装依赖包
为了避免后期的问题，安装了大量可能用到的包。即使提示没有安装包，接着往下执行即可
yum install -y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers libmcrypt-devel mhash mcrypt openldap openldap-devel zlib-devel libxml2-devel libjpeg-devel libiconv-devel freetype-devel libpng-devel gd-devel curl-devel libxslt-devel
【2】libiconv安装
<1>源码安装
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar zxf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local/libiconv
make -j4
make install
<2>报错解决
make时，通常会遇到如下报错：
./stdio.h:1010:1: error: ‘gets’ undeclared here (not in a function)
解决方法：
vim /root/libiconv-1.14/srclib/stdio.h
注释掉：_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
【3】php编译安装
<1>下载php并安装
php官网链接：https://www.php.net/downloads.php
wget https://www.php.net/distributions/php-7.3.7.tar.gz
tar -xf php-7.3.7.tar.gz -C /apk/package
cd /apk/package/php-7.3.7
./configure --prefix=/apk/install/php-7.3.7 --with-config-file-path=/apk/install/php-7.3.7/etc --with-pdo-mysql=/apk/install/mysql/mysql-5.6.44/ --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir=/usr/local/libiconv --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --with-gettext --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-soap --enable-short-tags --enable-static --with-xsl --with-fpm-user=nginx --with-fpm-group=nginx --enable-ftp --enable-opcache=no --with-ldap --with-ldap-sasl
<2>如配置ldap模块，需要在make前，对ldap做链接，否则编译会报错
ln -s /usr/lib64/libldap* /usr/lib/
make -j4
make install
<3>如使用make后出现以下类似报错：
/usr/bin/ld: ext/ldap/.libs/ldap.o: undefined reference to symbol ‘ber_strdup’
解决方法如下：
vim Makefile
在以EXTRA_LIBS开头的一行结尾添加-llber
<4>编译安装
make -j4
make install
如编译php时，报错warning：configure:WARNING:unrecognizedoptions:–with-mysql
原因是php7版本不支持mysql模块，而是使用–with-pdo-mysql连接数据库，所以需要更换参数为–with-pdo-mysql
--with-config-file-path 指定配置文件位置
--with-pdo-mysq 指定数据库位置
--with-iconv-dir 指定libiconv目录
【4】php启动方式配置
<1>配置文件设置
(注意php.ini文件的存放位置)
ln -s /apk/install/php-7.3.7/bin/php /usr/bin/php
cp /apk/package/php-7.3.7/php.ini-production /apk/install/php-7.3.7/etc/php.ini
cd /apk/install/php-7.3.7/etc
cp php-fpm.conf.default php-fpm.conf
cd /apk/install/php-7.3.7/etc/php-fpm.d
cp www.conf.default www.conf
<2>启动脚本配置
cp /apk/package/php-7.3.7/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
/etc/init.d/php-fpm start
<3>配置php与zabbix相关参数
cd /apk/install/php-7.3.7/etc/
vim php.ini
post_max_size 16M
max_execution_time 300
max_input_time 300
date.timezone Asia/Shanghai
<4>php-fpm启动
/etc/init.d/php-fpm start
<5>查看支持的模块
php -m |grep ldap
LNMP验证
【1】示例1
此处123.123.123.123代表zabbix_server的IP
cat test.php
http://123.123.123.123/test.php
访问到如上页面即为成功
补充：
Configuration File(php.ini) Path为php.ini应存放的位置，php.ini放其他位置并不会生效
【2】示例2
cat mysql.php （php7以下版本）
cat mysqli.php （php7）
http://123.123.123.123/mysqli.php
访问页面得到OK即为成功（此php文件功能不完全，可能报错忽略即可）
