PHP (Hypertext Preprocessor 超文本预处理器)是通用服务器端脚本编程语言，主要用于web开发实现动态web页面，也是最早实现将脚本嵌入HTML源码文档中的服务器端脚本语言之一。同时，php还提供了一个命令行接口，因此，其也可以在大多数系统上作为一个独立的shell来使用

（一）编译安装nginx
1、安装依赖包
yum -y install pcre-devel zlib-devel gcc gcc-c++ make
2、创建运行用户、组
[root@localhost nginx-1.22.0]#useradd -M -s /sbin/nologin nginx
（Nginx 服务程序默认以 nobody 身份运行，建议为其创建专门的用户账号，以便更准确地控制其访问权限） useradd -M -s /sbin/nologin nginx
3、编译安装nginx
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \

（二）编译安mysql
1、安装Mysql环境依赖包
yum -y install \
ncurses \
ncurses-devel \
bison \
cmake
yum -y install gcc gcc-c++ cmake bison bison-devel zlib-devel libcurl-devel libarchive-devel boost-devel ncurses-devel gnutls-devel libxml2-devel openssl-devel libevent-devel libaio-devel

3、编译安装
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \

-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1
[root@localhost mysql-5.7.20]#make -j 2
[root@localhost mysql-5.7.20]#make install
4、修改mysql 配置文件
[root@localhost mysql-5.7.20]#vim /etc/my.cnf
[client]
port = 3306
socket=/usr/local/mysql/mysql.sock
[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES
5、更改mysql安装目录和配置文件的属主属组
[root@localhost mysql-5.7.20]#chown -R mysql:mysql /usr/local/mysql/
[root@localhost mysql-5.7.20]#chown mysql:mysql /etc/my.cnf
6、设置路径环境变量
[root@localhost mysql-5.7.20]#echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile
[root@localhost mysql-5.7.20]#source /etc/profile
7、初始化数据库
[root@localhost mysql-5.7.20]#cd /usr/local/mysql/bin/
./mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
8、添加mysqld系统服务
[root@localhost bin]#cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
[root@localhost bin]#systemctl daemon-reload
[root@localhost bin]#systemctl start mysqld.service
[root@localhost bin]#systemctl status mysqld.service
[root@localhost bin]#systemctl enable mysqld.service
9、修改mysql 的登录密码
[root@localhost bin]#mysqladmin -u root -p password "abc123"
mysqladmin -u root -p password "abc123"
给root账号设置密码为abc123，提示输入的是原始密码（为空）要求输入的是原密码直接回车即可
10、授权远程登录
[root@localhost bin]#mysql -uroot -pabc123
（三）编译安装php软件
1、安装环境依赖包
yum -y install gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel
2、编译安装

--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip
[root@localhost php-7.1.10]#make -j 2
[root@localhost php-7.1.10]#make install
3、调整PHP配置文件
[root@localhost php-7.1.10]#ls php.ini-development
php.ini-development
[root@localhost php-7.1.10]#cp php.ini-development /usr/local/php/lib/php.ini
[root@localhost php-7.1.10]#vim /usr/local/php/lib/php.ini
修改内容
date.timezone = Asia/Shanghai
mysqli.default_socket = /usr/local/mysql/mysql.sock
调整主配置文件：
[root@localhost php-7.1.10]#cd /usr/local/php/lib/
[root@localhost lib]#ls
php php.ini
[root@localhost lib]#cd php/
[root@localhost php]#ls
Archive Console doc OS pearcmd.php peclcmd.php System.php XML
build data extensions PEAR PEAR.php Structures test
[root@localhost php]#cd ..
[root@localhost lib]#ls
php php.ini
[root@localhost lib]#cd ..
[root@localhost php]#ls
bin etc include lib php sbin var
[root@localhost php]#pwd
/usr/local/php
[root@localhost php]#cd etc/
[root@localhost etc]#ls
pear.conf php-fpm.conf.default php-fpm.d
[root@localhost etc]#pwd
/usr/local/php/etc
[root@localhost etc]#cp php-fpm.conf.default php-fpm.conf
[root@localhost etc]#ls
pear.conf php-fpm.conf php-fpm.conf.default php-fpm.d
[root@localhost etc]#vim php-fpm.conf
调整进程服务配置文件：
调整扩展配置文件：
[root@localhost etc]#cd php-fpm.d/
[root@localhost php-fpm.d]#ls
www.conf.default
[root@localhost php-fpm.d]#cp www.conf.default www.conf
[root@localhost php-fpm.d]#ls
www.conf www.conf.default
[root@localhost php-fpm.d]#
php有三个配置文件：
php.ini 主配置文件
php-fpm.conf 进程服务配置文件
www.conf 扩展配置文件
#调整主配置文件：cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini
vim /usr/local/php/lib/php.ini
--1170行--修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
--939行--取消注释，修改
date.timezone = Asia/Shanghai
#调整进程服务配置文件：cd /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
--17行--去掉";"注释
pid = run/php-fpm.pid
#调整扩展配置文件：cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf
4、路径优化
[root@localhost php-fpm.d]#ln -s /usr/local/php/bin/* /usr/local/bin/
[root@localhost php-fpm.d]#ln -s /usr/local/php/sbin/* /usr/local/sbin/
5、启动php-fpm
[root@localhost php-fpm.d]#cd /opt/php-7.1.10/sapi/fpm/
[root@localhost fpm]#ls
config.m4 init.d.php-fpm Makefile.frag php-fpm.8.in php-fpm.service status.html.in www.conf.in
CREDITS init.d.php-fpm.in php-fpm php-fpm.conf php-fpm.service.in tests
fpm LICENSE php-fpm.8 php-fpm.conf.in status.html www.conf
[root@localhost fpm]#pwd
/opt/php-7.1.10/sapi/fpm
[root@localhost fpm]#cp /opt/php-7.1.10/sapi/fpm/php-fpm.service /usr/lib/systemd/system/
[root@localhost fpm]#
[root@localhost fpm]#systemctl daemon-reload
[root@localhost fpm]#systemctl start php-fpm.service
[root@localhost fpm]#systemctl status php-fpm.service

[root@localhost fpm]#
（四）配置 Nginx支持PHP解析
[root@localhost fpm]#vim /usr/local/nginx/conf/nginx.conf
[root@localhost fpm]#nginx -s reload
[root@localhost fpm]#systemctl restart nginx.service
1、修改配置文件
2、写php测试页面
[root@localhost html]#vim /usr/local/nginx/html/index.php
<?php
phpinfo();
?>
[root@localhost html]#
3、去浏览器验证
4、验证数据库工作是否正常
CREATE DATABASE bbs;
GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY 'admin123';
GRANT all ON bbs.* TO 'bbsuser'@'localhost' IDENTIFIED BY 'admin123';
flush privileges;
重新编辑测试页：
<?php
$link=mysqli_connect('192.168.246.7','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>
浏览器访问
（五）安装论坛
[root@localhost ~]#cd /opt
[root@localhost opt]#ls
dir_SC_UTF8 mysql-5.7.20 nginx-1.22.0 php-7.1.10 说明.htm
Discuz_X3.4_SC_UTF8.zip mysql-boost-5.7.20.tar.gz nginx-1.22.0.tar.gz php-7.1.10.tar.bz2
[root@localhost opt]#unzip Discuz_X3.4_SC_UTF8.zip
[root@localhost opt]#cd dir_SC_UTF8/
[root@localhost dir_SC_UTF8]#ls
readme upload utility
[root@localhost dir_SC_UTF8]#cp -r upload/ /usr/local/nginx/html/bbs/
[root@localhost dir_SC_UTF8]#cd /usr/local/nginx/html/bbs/
[root@localhost bbs]#ls
admin.php archiver crossdomain.xml forum.php index.php member.php portal.php source uc_client
api config data group.php install misc.php robots.txt static uc_server
api.php connect.php favicon.ico home.php m plugin.php search.php template
[root@localhost bbs]#chmod -R 777 ./config/
[root@localhost bbs]#chmod -R 777 ./data/
[root@localhost bbs]#chmod -R 777 ./uc_client/
[root@localhost bbs]#chmod -R 777 ./uc_server/
1、部署 Discuz
2、调整论坛目录的权限：
调整论坛目录的权限:
cd /usr/local/nginx/html/bbs/
chown -R nginx.nginx ./config/
chown -R nginx.nginx ./data/
chown -R nginx.nginx ./uc_client/
chown -R nginx.nginx ./uc_server/
都要处理
chmod -R 777 ./config/
chmod -R 777 ./data/
chmod -R 777 ./uc_client/
chmod -R 777 ./uc_server/
3、论坛页面访问
数据库默认端口号3306
(六)安装博客
[root@zzcentos1 opt]#cp -r wordpress /usr/local/nginx/html/
[root@zzcentos1 opt]#cd /usr/local/nginx/html/
[root@zzcentos1 html]#ls
50x.html bbs index.html index.php wordpress
[root@zzcentos1 html]#chmod -R 777 wordpress/
[root@zzcentos1 html]#ls
50x.html bbs index.html index.php wordpress
[root@zzcentos1 html]#
建数据库名
CREATE DATABASE blog;
GRANT all ON blog.* TO 'bloguser'@'%' IDENTIFIED BY 'admin123';
GRANT all ON blog.* TO 'bloguser'@'localhost' IDENTIFIED BY 'admin123';
flush privileges;
wordpress/wp-admin
去浏览器访问
