Mysql安装：
1.安装mysql
wget -c https://repo.mysql.com//mysql57-community-release-el7-11.noarch.rpm rpm -ivh mysql57-community-release-el7-11.noarch.rpm yum install mysql-server -y
2.设定mysql开机启动
systemctl enable mysqld.service systemctl start mysqld.service systemctl status mysqld.service
3.修改密码
cat /var/log/mysqld.log |grep "A temporary password" #获取默认密码
mysqladmin -u root -p password #不登录mysql修改mysql的root密码
Nginx安装：
1.安装必要的库文件
yum install gcc pcre-devel openssl-devel -y
2.下载Nginx源码包
cd /tmp/ wget -c http://nginx.org/download/nginx-1.12.2.tar.gz
3.安装Nginx
groupadd nginx useradd nginx -g nginx -s /sbin/nologin -M tar -zxf nginx-1.12.2.tar.gz cd nginx-1.12.2/ ./configure --prefix=/usr/local/nginx-1.12.2/ --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module make && make install && echo $? ln -s /usr/local/nginx-1.12.2/ /usr/local/nginx
4.创建nginx.service服务文件
vim /lib/systemd/system/nginx.service
nginx.service文件内容如下：
[Unit] Description=nginx 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
5.设置nginx开机自动启动：
systemctl enable nginx.service systemctl start nginx.service systemctl status nginx.service
安装php：
1.安装依赖库：
yum install -y 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
会提示没有软件包libmcrypt和libmcrypt-devel，更新epel源地址：http://mirrors.aliyun.com/help/epel
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum install -y libmcrypt libmcrypt-devel
2.下载php
cd /tmp wget http://cn2.php.net/distributions/php-7.2.3.tar.gz
3.编译安装php
cd /tmp tar -zxf php-7.2.3.tar.gz cd php-7.2.3/ ./configure --prefix=/usr/local/php-7.2.3 --disable-fileinfo --enable-fpm --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-openssl --with-zlib --with-curl --enable-ftp --with-gd --with-xmlrpc --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-mbstring --enable-zip --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --without-pear --enable-bcmath make && make install && echo $? ln -s /usr/local/php-7.2.3/ /usr/local/php
4.配置php-fpm运行账号
groupadd php-fpm-user
useradd -M -g php-fpm-user -s /sbin/nologin php-fpm-user
cp php.ini-development /etc/php.ini
cp /usr/local/php-7.2.3/etc/php-fpm.conf.default /usr/local/php-7.2.3/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
注意：cat /usr/local/php/etc/php-fpm.conf.default 查看最后一行
vim /usr/local/php/etc/php-fpm.d/www.conf
搜索“user”设置运行账号：
user=php-fpm-user
group=php-fpm-user
6. 设置php-fpm为系统服务：
vim /etc/systemd/system/php-fpm.service
文件内容：
[Unit] Description=php-fpm After=network.target [Service] Type=forking ExecStart=/usr/local/php/sbin/php-fpm PrivateTmp=True [Install] WantedBy=multi-user.target
7.php-fpm服务开机自动启动
systemctl enable php-fpm.service systemctl start php-fpm.service systemctl status php-fpm.service
8.配置nginx支持php
