一、安装nginx
1、yum安装nginx
yum -y install nginx
2、检查nginx的状态，开启nginx和开机自启
（1）检查nginx的状态
systemctl status nginx
（2）启动nginx
systemctl start nginx
（3）开机自启nginx
systemctl enable nginx
3、配置nginx访问日志（可不配置）
（1）创建存放目录
mkdir -p /www/app/nginx/log/access/
mkdir -p /www/app/nginx/log/error/
chmod 777 -r /www
（2）配置nginx日志格式（找到左边的字段，修改右边信息）
我要评论vim /etc/nginx/nginx.conf
error_log /www/app/nginx/log/error/error.log;
log_format main '"$server_name" "$server_addr:$server_port" "$remote_addr" "$time_local" "$request_method" "$request_uri" "$server_protocol" "$status" "$request_time" "$bytes_sent" "$body_bytes_sent" "$http_range" "$http_referer" "$http_user_agent" "$request_body" "$request_completion"';
access_log /www/app/nginx/log/access/access.log main;
二、安装mysql5.7
1、下载yum repository,然后安装（大概25k左右）
mkdir /download
cd /download/
wget http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
2、安装mysql5.7
yum -y install mysql-community-server
3、启动mysql，以及开机自启
启动
systemctl start mysqld
开机自启
systemctl enable mysqld
4、修改密码
（1）获取初始密码
cat /var/log/mysqld.log |grep password
（2）登录(用上面的密码)
mysql -uroot -p
（3）修改密码
alter user 'root'@'localhost' identified by '123456';
密码太多简单，不符合策略，则使用复杂一点的密码
alter user 'root'@'localhost' identified by '123456abc#';
（4）、若是密码过于复杂，难记，则修改密码策略，再修改一个简单的密码（正式环境不建议使用）
修改策略
set global validate_password_length=4;
set global validate_password_policy=0;
查看策略
show variables like 'validate_password%';
修改密码
alter user 'root'@'localhost' identified by '123456';
三、安装php7.2
1、下载php7.2(19m左右)
cd /download
wget https://www.php.net/distributions/php-7.2.24.tar.gz
解压
tar zxvf php-7.2.24.tar.gz
cd php-7.2.24
2、安装依赖组件
yum -y install gcc gcc-c++ libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses curl gdbm-devel db4-devel libxpm-devel libx11-devel gd-devel gmp-devel expat-devel xmlrpc-c xmlrpc-c-devel libicu-devel libmcrypt-devel libmemcached-devel
3、编译安装
./configure \ --prefix=/usr/local/php \ --with-config-file-path=/etc \ --enable-fpm \ --with-fpm-user=nginx \ --with-fpm-group=nginx \ --enable-inline-optimization \ --disable-debug \ --disable-rpath \ --enable-shared \ --enable-soap \ --with-libxml-dir \ --with-xmlrpc \ --with-openssl \ --with-mhash \ --with-pcre-regex \ --with-sqlite3 \ --with-zlib \ --enable-bcmath \ --with-iconv \ --with-bz2 \ --enable-calendar \ --with-curl \ --with-cdb \ --enable-dom \ --enable-exif \ --enable-fileinfo \ --enable-filter \ --with-pcre-dir \ --enable-ftp \ --with-gd \ --with-openssl-dir \ --with-jpeg-dir \ --with-png-dir \ --with-zlib-dir \ --with-freetype-dir \ --enable-gd-jis-conv \ --with-gettext \ --with-gmp \ --with-mhash \ --enable-json \ --enable-mbstring \ --enable-mbregex \ --enable-mbregex-backtrack \ --with-libmbfl \ --with-onig \ --enable-pdo \ --with-mysqli=mysqlnd \ --with-pdo-mysql=mysqlnd \ --with-zlib-dir \ --with-pdo-sqlite \ --with-readline \ --enable-session \ --enable-shmop \ --enable-simplexml \ --enable-sockets \ --enable-sysvmsg \ --enable-sysvsem \ --enable-sysvshm \ --enable-wddx \ --with-libxml-dir \ --with-xsl \ --enable-zip \ --enable-mysqlnd-compression-support \ --with-pear \ --enable-opcache
4、make && make install
5、拷贝php.ini
cp /download/php-7.2.24/php.ini-development /etc/php.ini
6、php-fpm的配置与使用
（1）复制php-fpm.conf
cd /usr/local/php/etc/
cp php-fpm.conf.default php-fpm.conf
（2）复制www.conf
cd /usr/local/php/etc/php-fpm.d
cp www.conf.default www.conf
（3）php-fpm系统服务
vi /etc/systemd/system/php-fpm.service
[unit]
description=php-fpm
after=network.target
[service]
type=forking
execstart=/usr/local/php/sbin/php-fpm
privatetmp=true
[install]
wantedby=multi-user.target
（4）启动php-fpm跟开机自启
systemctl start php-fpm
systemctl enable php-fpm
