zabbix-web切换为nginx及https
1、背景和环境
zabbix使用了很久，安装的时候并没有选择复杂的源码编译安装，所以默认采用了apache的httpd提供web服务。由于对httpd并没有深入研究，而且个人对httpd的配置文件格式很不感冒，怎么办？当然是换nginx呀！
本文中的环境如下：
系统版本：CentOS Linux release 7.4.1708 (Core)
软件版本：
zabbix 4.0.0
nginx 1.16.0
php 5.6.40
2、安装nginx
2.1、编译参数
apache httpd通过模块来使用php，nginx连接php则需要单独安装php，首先编译安装nginx
编译参数和步骤如下，来自我的github
#!/bin/bash
#定义版本
VERSION=1.16.0
#安装依赖包
yum install gcc gcc-c++ glibc pcre-devel zlib-devel openssl-devel -y
#用户创建
/usr/sbin/useradd -M -s /sbin/nologin www
#编译安装
cd ~
wget http://nginx.org/download/nginx-$VERSION.tar.gz
tar xf nginx-$VERSION.tar.gz
cd nginx-$VERSION
./configure --prefix=/usr/local/nginx --pid-path=/usr/local/nginx/run/nginx.pid --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-http_realip_module
make && make install
cd /usr/local/nginx/conf/
grep -Ev '^$|#' nginx.conf.default > nginx.conf
#清除包
cd ~
rm -rf nginx-$VERSION nginx-$VERSION.tar.gz2.2、修改配置文件并配置https
/usr/local/nginx/confnginx.conf
[[email protected] ~]# cat /usr/local/nginx/conf/nginx.conf
worker_processes 1;
events
worker_connections 1024;
http
include mime.types;

include /usr/local/nginx/conf/Include/*.conf;
cat /usr/local/nginx/conf/Include/zabbix.conf
[[email protected] ~]# cat /usr/local/nginx/conf/Include/zabbix.conf
server
listen 80;
server_name www.zabbix.cn;
return 301 https://www.zabbix.cn$request_uri;
server
listen 443 ssl;
server_name www.zabbix.cn
if ($host != 'www.zabbix.cn
return 403;

index index.php index.html index.htm;
ssl_certificate /usr/local/nginx/ssl-certs/2505454_www.zabbix.cn.pem;

fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
2.3、配置nginx为系统服务
vim /lib/systemd/system/nginx.service
[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
PrivateTmp=true
[Install]
WantedBy=multi-user.target- 加载系统服务
systemctl daemon-reload - 设置开机启动
systemctl enable nginx - 启动 nginx
systemctl start nginx - 停止
systemctl stop nginx 加载配置文件
systemctl reload nginx3、安装php
3.1、编译安装
3.1.1、编译参数
php的编译安装稍微复杂，复杂点就在于它的编译参数，php的编译参数很多，这里尽量最小化安装，如何选择参数，可通过在第一次安装zabbix的时候环境检测查看到，参数不满足是无法正常安装使用的，我通过本地虚拟机重新安装了一遍zabbix，得到具体环境参数如下，每列可依次理解为：名称、检测结果，需满足的结果、检测是否通过
PHP version 5.6.40 5.4.0 OK
PHP option "memory_limit" 128M 128M OK
PHP option "post_max_size" 8M 16M Fail
PHP option "upload_max_filesize" 2M 2M OK
PHP option "max_execution_time" 30 300 Fail
PHP option "max_input_time" -1 300 OK
PHP option "date.timezone" unknown Fail
PHP databases support mysql OK
PHP bcmath on OK
PHP mbstring on OK
PHP option "mbstring.func_overload" off off OK
PHP option "always_populate_raw_post_data" on off Fail
PHP sockets on OK
PHP gd 2.1.0 2.0 OK
PHP gd PNG support on OK
PHP gd JPEG support on OK
PHP gd FreeType support on OK
PHP libxml 2.9.1 2.6.15 OK
PHP xmlwriter on OK
PHP xmlreader on OK
PHP LDAP off Warning
PHP ctype on OK
PHP session on OK
PHP option "session.auto_start" off off OK
PHP gettext off Warning
PHP option "arg_separator.output" & & OK查看上述参数，最后确认一个合适的编译参数，如果第一次编译少了某些参数，也可通过不重新编译添加模块的方法，最终编译参数如下：
./configure --prefix=/usr/local/php-5.6.40 --enable-opcache --with-config-file-path=/usr/local/php-5.6.40/etc --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-fpm --enable-static --enable-inline-optimization --enable-sockets --enable-wddx --enable-zip --enable-calendar --enable-bcmath --enable-soap --with-zlib --with-iconv --with-gd --with-xmlrpc --enable-mbstring --with-curl --with-gettext --with-ldap --enable-ftp --with-mcrypt --with-freetype-dir=/usr/local/freetype.2.1.10 --with-jpeg-dir=/usr/local/jpeg.6 --with-png-dir=/usr/local/libpng.1.2.50 --disable-ipv6 --disable-debug --with-openssl --disable-maintainer-zts --disable-fileinfo3.1.2、排错
编译安装时可能出现的报错和解决办法如下，具体不做分析
报错一：
configure: error: Cannot find ldap.h解决办法：
yum install -y openldap openldap-devel报错二：
configure: error: Cannot find ldap libraries in /usr/lib.解决办法：
cp -frp /usr/lib64/libldap* /usr/lib/报错三：
//.usrlibs//lib64ldap.o/:liblber -undefined2.4.so.2 :reference errorto addingsymbol symbols':ber_scanf 'DSO
/missingusr /fromlib64 /commandliblber -line2.4.so.2

collect2: error: ld returned 1 exit status

/usr/lib64/liblber-2.4.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status解决办法：
vim Makefile 在这行最后添加-llber
EXTRA_LIBS = -lcrypt -lz -lresolv -lcrypt -lrt -lmcrypt -lldap -lpng -lz -ljpeg -lcurl -lz -lrt -lm -ldl -lnsl -lxml2 -lz -lm -ldl -lssl -lcrypto -lcurl -lxml2 -lz -lm -ldl -lssl -lcrypto -lfreetype -lxml2 -lz -lm -ldl -lxml2 -lz -lm -ldl -lcrypt -lxml2 -lz -lm -ldl -lxml2 -lz -lm -ldl -lxml2 -lz -lm -ldl -lxml2 -lz -lm -ldl -lxml2 -lz -lm -ldl -lssl -lcrypto -lcrypt -llber3.2、配置
编译安装完php后，需要修改配置文件php.ini中的内容以满足上述检测：
post_max_size = 16M
max_input_time = 300
max_execution_time = 300
date.timezone = Asia/Shanghai
always_populate_raw_post_data = -13.3、配置php为系统服务
编译安装php的，会在php目录生成很多二进制文件，找到init.d.php-fpm，拷贝到init.d下。
cp /usr/local/src/php-5.6.33/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm设置权限
chmod 755 /etc/init.d/php-fpm配置php-fpm.conf
vim /usr/local/etc/php-fpm.conf如果打开了pid配置，需要将pid（;pid = run/php-fpm.pid）前的;去掉。
启动
/etc/init.d/php-fpm start3.4、启动
编译配置没有问题，可正常启动
4、访问及排错
访问时出现的报错及解决办法如下
报错一：
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‘解决办法：
chmod -R 755 /etc/zabbix/web报错二：
Database error
Error connecting to database: No such file or directory解决办法：修改php-fpm.conf
mysqli.default_socket = /var/lib/mysql/mysql.sock最终，切换nginx及配置https成功：
