数据库：
1，创建用户
[root@web02 ~]# useradd mysql -s /sbin/nologin -M
[root@web02 ~]# id mysql
uid=1002(mysql) gid=1002(mysql) 组=1002(mysql)
2，上传软件到指定的目录
[root@web02 ~]# cd /server/tools/
[root@web02 /server/tools]#
[root@web02 /server/tools]# rz
rz waiting to receive.
http://mirrors.163.com/mysql/Downloads/MySQL-5.7/ （下载地址，这里直接上传压缩包）
[root@web02 /server/tools]# ls -lsh
总用量 616M
615M -rw-r--r-- 1 root root 615M 5月 4 20:48 mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
0 drwxr-xr-x 9 www www 204 4月 30 12:04 nginx-1.16.0
1012K -rw-r--r-- 1 root root 1009K 4月 23 21:58 nginx-1.16.0.tar.gz
[root@web02 /server/tools]# tar xf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
[root@web02 /server/tools]# mv mysql-5.7.26-linux-glibc2.12-x86_64 /application/mysql-5.7.26
[root@web02 /server/tools]# ln -s /application/mysql-5.7.26/ /application/mysql
[root@web02 /server/tools]# ls /application/mysql/
bin COPYING docs include lib man README share support-files
3，配置配置文件
yum安装mariadb的默认的my.cnf（mysql的配置文件）
[root@web02 /server/tools]# ls -l /etc/my.cnf
-rw-r--r--. 1 root root 570 8月 16 2018 /etc/my.cnf
卸载依赖包yum remove mariadb（禁用），rpm -e --nodeps mariadb-libs（用这个卸载）
[root@web02 /server/tools]# rpm -e --nodeps mariadb-libs
[root@web02 /server/tools]# ls -l /etc/my.cnf
ls: 无法访问/etc/my.cnf: 没有那个文件或目录
[root@web02 /server/tools]# vim /etc/my.cnf
[mysqld]
basedir = /application/mysql/
datadir = /application/mysql/data
socket = /tmp/mysql.sock
server_id = 1
port = 3306
log_error = /application/mysql/data/oldboy_mysql.err
[mysql]
socket = /tmp/mysql.sock
prompt = oldboy [\\d]>
4，初始化数据库
[root@web02 /server/tools]# rpm -qa mariadb-libs
[root@web02 /server/tools]# yum install libaio-devel -y
[root@web02 /server/tools]# mkdir -p /application/mysql/data
[root@web02 /server/tools]# chown -R mysql.mysql /application/mysql/
[root@web02 /server/tools]# /application/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql/ --datadir=/application/mysql/data
当初始化失败提示时执行以下步骤，error类似的字符串，清空/data
cd /application/mysql/data
rm -fr *
5，配置启动服务
[root@web02 /application/mysql/support-files]# cat /etc/systemd/system/mysqld.service
[Unit]
Description=MySQL Server by oldboy
Documentation=man:mysqld(8)
Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html

6，配置环境变量登录
[root@web02 /application/mysql/support-files]# echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile
[root@web02 /application/mysql/support-files]# tail -1 /etc/profile
export PATH=/application/mysql/bin:$PATH
[root@web02 /application/mysql/support-files]# . /etc/profile
[root@web02 /application/mysql/support-files]# echo $PATH

安装PHP
yum安装：简单、方便、高效
编译安装PHP
1，安装PHP调用的库
yum install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel -y
yum install freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libxslt-devel -y
cd /server/tools/ 上传libiconv-1.16.tar.gz
tar zxf libiconv-1.16.tar.gz
cd libiconv-1.16
./configure --prefix=/application/libiconv
make && make install
cd ../
yum install libmcrypt-devel -y
yum install mhash -y
yum install mcrypt -y
2，安装PHP
cd /server/tools/
上传php-7.3.5.tar
tar xf php-7.3.5.tar.gz
cd php-7.3.5/
./configure \
--prefix=/application/php-7.3.5 \
--enable-mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-iconv-dir=/application/libiconv \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--disable-rpath \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--with-gd \
--with-openssl \
--with-mhash \
--enable-pcntl \

--with-fpm-group=nginx \
--enable-ftp \
--enable-opcache=no
make && make install
[root@web02 /server/tools/php-7.3.5]# echo $?
0
将nginx的用户和PHP的用户统一：nginx
[root@web02 /server/tools/php-7.3.5]# useradd nginx -u 1111 -s /sbin/nologin -M
[root@web02 /server/tools/php-7.3.5]# id nginx
uid=1111(nginx) gid=1111(nginx) 组=1111(nginx)
前面安装nginx的时候如果是www就修改nginx配置文件（编译的时候就改用nginx，就不用这一步）
[root@web02 /server/tools/php-7.3.5]# vim /application/nginx/conf/nginx.conf
worker_processes 1;
user nginx nginx;
创建软链接
[root@web02 ~]# ln -s /application/php-7.3.5/ /application/php
[root@web02 ~]# ls /application/php/
bin etc include lib php sbin var
3，配置php.ini（PHP解析器配置文件）
[root@web02 /application/php]# cd /server/tools/php-7.3.5/
[root@web02 /server/tools/php-7.3.5]# ls php.ini-*
php.ini-development php.ini-production
[root@web02 /server/tools/php-7.3.5]# cp php.ini-development /application/php/lib/php.ini
[root@web02 /server/tools/php-7.3.5]# ls -l /application/php/lib/php.ini
-rw-r--r-- 1 root root 71648 5月 6 11:51 /application/php/lib/php.ini
4，配置PHP FPM
[root@web02 /server/tools/php-7.3.5]# cd /application/php/etc/
[root@web02 /application/php/etc]# ls
pear.conf php-fpm.conf.default php-fpm.d
[root@web02 /application/php/etc]# cp php-fpm.conf.default php-fpm.conf
[root@web02 /application/php/etc]# cd php-fpm.d/
[root@web02 /application/php/etc/php-fpm.d]# ls
www.conf.default
[root@web02 /application/php/etc/php-fpm.d]# cp www.conf.default www.conf
[root@web02 /application/php/etc/php-fpm.d]# ls
www.conf www.conf.default
5，启动PHP服务
[root@web02 /application/php/etc/php-fpm.d]# /application/php/sbin/php-fpm
[root@web02 /application/php/etc/php-fpm.d]# netstat -lntup|grep php-fpm
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 12214/php-fpm: mast
6，开机自启动
[root@web02 /application/php/etc/php-fpm.d]# tail -2 /etc/rc.local
/application/nginx/sbin/nginx
/application/php/sbin/php-fpm
7，配置nginx转发PHP请求
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
[root@web02 /application/nginx/conf/extra]# cat 03_blog.conf
server {
listen 80;
server_name blog.etiantian.org;
location / {
root html/blog;
index index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
[root@web02 /application/nginx/conf]# nginx -t
nginx: the configuration file /application/nginx-1.16.0//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.16.0//conf/nginx.conf test is successful
[root@web02 /application/nginx/conf]# nginx -s reload
9，测试PHP连接mysql
[root@web02 /application/nginx/html/blog]# cat /application/nginx/html/blog/test_mysql.php
<?php
//$link_id=mysqli_connect('主机名','用户','密码');
$link_id=mysqli_connect('localhost','root','oldboy123') or mysql_error();
if($link_id){
echo "mysql successful by oldboy.\n";
}else{
echo mysql_error();
}
?>
[root@web02 /application/nginx/html/blog]# /application/php/bin/php /application/nginx/html/blog/test_mysql.php
mysql successful by oldboy.
