php:192.168.31.100
zabbix:192.168.31.100
mariadb:192.168.31.101

准备

#两台服务器都关闭防火墙和selinux
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

安装nginx

下载nginx源码包,安装nginx依赖包

wget -P /usr/local/src http://nginx.org/download/nginx-1.16.1.tar.gz
yum -y install gcc gcc-c++ make pcre zlib openssl openssl-devel

解压nginx源码包,创建www用户，开始编译安装

cd /usr/local/src
tar -zxf nginx-1.16.1.tar.gz 
cd nginx-1.16.1
useradd www -s /sbin/nologin
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make 
make install

创建软链接文件

ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx
nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

安装php7.3

yum -y install epel-release
yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum -y install yum-utils
yum install -y php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xmll php73-php-xmlwriter
#修改php启动用户为www
sed -i 's/user = apache/user = www/g;s/group = apache/group = www/g' /etc/opt/remi/php73/php-fpm.d/www.conf
#删除空行和注释行
sed -i '/^;/d;/^$/d;/ *;/d;/^[ \t]*$/d' /etc/opt/remi/php73/php.ini
#修改php默认配置
sed -i 's/post_max_size = 8M/post_max_size = 16M/g;s/max_execution_time = 30/max_execution_time = 300/g;s/max_input_time = 60/max_input_time = 300/g' /etc/opt/remi/php73/php.ini
sed -i '/max_input_time = 300/a date.timezone = Asia/Shanghai' /etc/opt/remi/php73/php.ini

安装zabbix

下载zabbix源码包，安装依赖包

wget -P /usr/local/src https://cdn.zabbix.com/zabbix/sources/stable/5.0/zabbix-5.0.2.tar.gz
yum -y install curl curl-devel net-snmp net-snmp-devel perl-DBI  gcc-c++ gcc make libevent libevent-devel mariadb mysql-devel

创建zabbix 组和用户

make
make install
ln -s /usr/local/zabbix/sbin/zabbix_server /usr/local/sbin/
cp misc/init.d/tru64/zabbix_server /etc/init.d/zabbix_server
chmod o+x /etc/init.d/zabbix_server

修改zabbix配置文件

cp /usr/local/zabbix/etc/zabbix_server.conf /usr/local/zabbix/etc/zabbix_server.conf.bak
sed -i '/^#/d;/^$/d;/ *#/d;/^[ \t]*$/d' /usr/local/zabbix/etc/zabbix_server.conf
sed -i '/DBName=zabbix/i DBHost=192.168.31.101' /usr/local/zabbix/etc/zabbix_server.conf
sed -i '/DBUser=zabbix/a DBPassword=zabbix' /usr/local/zabbix/etc/zabbix_server.conf

安装mariadb数据库

yum -y install mariadb mariadb-server mariadb-client mariadb-devel
systemctl start mariadb
mysql_secure_installation
systemctl enable mariadb
mysql -u root -p 
Enter password: 
MariaDB [(none)]> create database zabbix charset=utf8;
MariaDB [(none)]> grant all on zabbix.* to zabbix@'%' identified by 'zabbix';
MariaDB [(none)]> flush privileges;

创建zabbix虚拟主机

mkdir -p /usr/local/nginx/conf/vhosts
vim /usr/local/nginx/conf/vhosts/zabbix.conf
server {
        listen       80 default_server;

mkdir /usr/local/nginx/html/zabbix

cd zabbix-5.0.2
cp -Rf ui/* /usr/local/nginx/html/zabbix/

导入zabbix SQL文件到数据库中

cd zabbix-5.0.2
mysql -h 192.168.31.101 -uzabbix -pzabbix zabbix <database/mysql/schema.sql 
mysql -h 192.168.31.101 -uzabbix -pzabbix zabbix <database/mysql/images.sql 
mysql -h 192.168.31.101 -uzabbix -pzabbix zabbix <database/mysql/data.sql

启动nginx、php和zabbix

nginx
systemctl restart php73-php-fpm
/etc/init.d/zabbix_server start

访问http://IP/setup.php

错误

访问网页显示 http 500

查看日志
查看nginx 错误日志,php执行函数session_start出错，原因是没有目录或权限问题

解决

[root@localhost html]# ll /var/opt/remi/php73/lib/php/session
total 4
-rw-------. 1 apache apache 33 Mar 29 20:07 sess_9q7gcmffnbde2gk0br6eqpbohq
查看有这个目录，但目录所属为apache用户，修改所属
chown -R root:www /var/opt/remi/php73/lib/php/session
重新启动php和nginx
再次访问可看到恢复正常
