环境:
操作系统:CentOS 6.8 x86_64（关闭SELinux、iptables）
Nginx：1.10.1
PHP: 7.0.10
MySQL：5.7.13
Zabbix：3.0.4
一.安装MySQL
1.安装依赖
yum -y install gcc gcc-devel gcc-c++ gcc-c++-devel libaio-devel boost boost-devel autoconf* automake* zlib* libxml* ncurses-devel ncurses libgcrypt* libtool* cmake openssl openssl-devel bison bison-devel unzip numactl-devel net-snmp-devel net-snmp-utils
2.卸载mysql-libs,否则下面安装mysql的时候会报错
rpm -e --nodeps mysql-libs
3.下载解压及安装
wget tar xf mysql-5.7.13-1.el6.x86_64.rpm-bundle.tar
rpm -ivh `ls |grep mysql-community|grep -v test`
4.由于mysql 5.7跟之前的5.6安全性有很大提升，有很多地方是不一样的
先重置密码
#修改默认字符集
sed -i '/\[mysqld\]/a\character-set-server=utf8' my.cnf
#启动mysqld,并进行初始化
/etc/init.d/mysqld start
#停止mysqld，以便进行无密码启动
/etc/init.d/mysqld stop
#无密码启动mysql
mysqld_safe --skip-grant-tables &
mysql
#注意新版的mysql 5.7在mysql.user表下已经没有password字段了
mysql> update mysql.user set authentication_string=password('123456.abcd') where user='root' and Host = 'localhost';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
#会被告知你的密码不符合当前策略
#修改对应的密码策略，但是密码也至少为9位
mysql> set global validate_password_policy=0;
mysql> update mysql.user set authentication_string=password('123456.abcd') where user='root' and Host = 'localhost';
service mysqld restart二.编译安装PHP 7.0.10
1.安装EPEL源及安装对应的依赖包
rpm -ivh http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum -y install libmcrypt-devel mcrypt mhash gd-devel ncurses-devel libxml2-devel bzip2-devel libcurl-devel curl-devel libjpeg-devel libpng-devel freetype-devel net-snmp-devel openssl-devel
2.安装libiconv
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/libiconv1.14
make && make install
cd ..
3.下载及编译php
wget http://cn2.php.net/get/php-7.0.10.tar.gz/from/this/mirror
tar zxf mirror
cd php-7.0.10/
./configure --prefix=/usr/local/php7.0.10 --with-config-file-path=/usr/local/php7.0.10/etc --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir=/usr/local/libiconv1.14 --with-pcre-regex --with-zlib --with-bz2 --enable-calendar --with-curl --enable-dba --with-libxml-dir --enable-ftp --with-gd --with-jpeg-dir --with-png-dir --with-zlib-dir --with-freetype-dir --enable-gd-native-ttf --with-mhash --enable-mbstring --with-mcrypt --enable-pcntl --enable-xml --disable-rpath --enable-shmop --enable-sockets --enable-zip --enable-bcmath --with-snmp --disable-ipv6 --with-gettext --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-openssl
#注意不能有--enable-gd-jis-conv参数，否则后面图形乱码
make && make install
4.修改相应参数

useradd -g www -u 10080 -s /sbin/nologin -d /dev/null www
三.安装Nginx
1.下载及安装nginx
wget http://nginx.org/download/nginx-1.10.1.tar.gz
tar zxf nginx-1.10.1.tar.gz
cd nginx-1.10.1
#隐藏Nginx版本
sed -i 's#1.10.1#2.2.14.0#g' src/core/nginx.h
sed -i 's#"nginx/"#"Apache/"#g' src/core/nginx.h
sed -i 's#"Server: nginx"#"Server: Apache"#g' src/http/ngx_http_header_filter_module.c
sed -i 's#nginx#Apache#g' src/http/ngx_http_special_response.c
./configure --prefix=/usr/local/nginx1.10.1 --user=www --group=www --with-http_stub_status_module --with-http_gzip_static_module --with-http_ssl_module
make && make install
sed -i 's#nginx/$nginx_version;#Apache/$nginx_version;#g' /usr/local/nginx1.10.1/conf/fastcgi.conf
2.配置Nginx
vim /usr/local/nginx1.10.1/conf/nginx.conf
user www www;
worker_processes 4;
error_log logs/error.log;
pid logs/nginx.pid;
worker_rlimit_nofile 65535;
events {
use epoll;
worker_connections 65535;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
fastcgi_param HTTP_PROXY "";
#隐藏后端服务器的相关参数
proxy_hide_header X-Powered-By;
proxy_hide_header X-Forwarded-For;
proxy_hide_header X-AspNet-Version;
proxy_hide_header X-AspNetMvc-Version;
proxy_hide_header Via;
proxy_hide_header X-Varnish;
proxy_hide_header Server;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.1;
gzip_comp_level 5;
gzip_disable "MSIE [1-6]\.";
gzip_types text/plain text/css text/xml application/javascript application/x-javascript;
gzip_vary on;
include host/*.conf;
}3.配置站点
mkdir /usr/local/nginx1.10.1/conf/host
vim /usr/local/nginx1.10.1/conf/host/zabbix.conf
server {
listen 80;
server_name localhost zabbix;
location / {
root /var/www/html;
index index.html index.htm index.php;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
fastcgi_pass unix:/tmp/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param HTTP_PROXY "";
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
}四.安装Zabbix
1.下载及安装zabbix
yum -y install OpenIPMI-devel
wget http://120.52.73.47/nchc.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.0.4/zabbix-3.0.4.tar.gz
tar -zxvf zabbix-3.0.4.tar.gz
cd zabbix-3.0.4
./configure --prefix=/usr/local/zabbix3.0.4 --enable-server --with-mysql --with-net-snmp --with-libxml2 --with-libcurl --with-openipmi --enable-agent
make && make installl
2.配置zabbix
cp misc/init.d/fedora/core5/zabbix_server /etc/init.d/
cp misc/init.d/fedora/core5/zabbix_agentd /etc/init.d/
sed -i 's#/usr/local/sbin/zabbix_server#/usr/local/zabbix3.0.4/sbin/zabbix_server#g' /etc/init.d/zabbix_server
sed -i 's#/usr/local/sbin/zabbix_agentd#/usr/local/zabbix3.0.4/sbin/zabbix_agentd#g' /etc/init.d/zabbix_agentd
3.复制WEB站点
mkdir /var/www/html/zabbix
cp -rf frontends/php/* /var/www/html/zabbix
4.zabbix乱码图形处理
将Windows操作系统的C:\Windows\Fonts\simkai.ttf字体文件上传至/var/www/html/zabbix/font。防止出现乱码情况
sed -i 's#DejaVuSans#simkai#g' /var/www/html/zabbix/include/defines.inc.php
5.使用MySQL创建zabbix数据库并授权
mysql -uroot -p
mysql> create database zabbix character set utf8;
mysql> grant all on zabbix.* to 'zabbix'@'localhost' identified by 'zabbix.localhost';
6.导入数据库
进入zabbix-3.0.4源码文件目录
mysql -uroot -p zabbix < database/mysql/schema.sql
mysql -uroot -p zabbix < database/mysql/data.sql
mysql -uroot -p zabbix < database/mysql/p_w_picpaths.sql
7.修改zabbix_server配置文件，以下是我的配置文件
egrep -v '^:|^#' /usr/local/zabbix3.0.4/etc/zabbix_server.conf|awk 'NF>0'
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix.localhost
StartPollers=10
StartPingers=4
StartDiscoverers=4
JavaGateway=127.0.0.1
JavaGatewayPort=10052
StartJavaPollers=5
StartVMwareCollectors=5
VMwareFrequency=60
VMwareCacheSize=8M
8.再修改zabbix web目录下的配置文件
vim /var/www/html/zabbix3.0.4/conf/zabbix.conf.php
QA:
1.zabbix乱码问题
a.数据库字符集问题，创建数据库时指定字符集
create database zabbix character set utf8;
b.未上传中文字体，或者未修改include/define.inc.php文件
c.编译PHP时携带有--enable-gd-jis-conv参数，如果带有这个参数，画图的时候出现
2.php7安装memcache问题
git clone
cd pecl-memcache
/usr/local/php7.0.10/bin/phpize
./configure --with-php-config=/usr/local/php7.0.10/bin/php-config
make && make install
echo 'extension = "memcache.so"'>>/usr/local/php7.0.10/etc/php.ini
#检查php是否加载memcache模块
/usr/local/php7.0.10/bin/php -m |grep memcache
#重启php-fpm服务以加载memcache模块
/etc/init.d/php-fpm restart
