实验：编译安装httpd-2.4.38
1、下载源码并解压缩 [root@centos7 data]#wget http://mirrors.shu.edu.cn/apache//httpd/httpd-2.4.38.tar.bz2 --2019-03-03 12:45:15-- http://mirrors.shu.edu.cn/apache//httpd/httpd-2.4.38.tar.bz2 Resolving mirrors.shu.edu.cn (mirrors.shu.edu.cn)... 202.121.199.235 Connecting to mirrors.shu.edu.cn (mirrors.shu.edu.cn)|202.121.199.235|:80... connected.

tar xvf apr-1.6.5.tar.bz2
tar xvf apr-util-1.6.1.tar.bz2
tar xvf httpd-2.4.38.tar.bz2
[root@centos7 data]#ls
apr-1.6.5.tar.bz2 apr-util-1.6.1.tar.bz2 httpd-2.4.38.tar.bz2
[root@centos7 data]#ls
apr-1.6.5 apr-1.6.5.tar.bz2 apr-util-1.6.1 apr-util-1.6.1.tar.bz2 httpd-2.4.38 httpd-2.4.38.tar.bz2
2、 将三个源码合并
[root@centos7 data]#mv apr-1.6.5 httpd-2.4.38/srclib/apr
[root@centos7 data]#mv apr-util-1.6.1 httpd-2.4.38/srclib/apr-util
[root@centos7 data]#ls httpd-2.4.38/srclib/
apr apr-util Makefile.in
3、 安装相关包 yum install gcc gcc-c++ glibc glibc-devel pcre-devel openssl-devel expat-devel
4、编译安装[root@centos7 httpd-2.4.38]#1、 cd httpd-2.4.38/
./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-included-apr --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork
2、make && make install
configure: summary of build options:
Server Version: 2.4.38
Install prefix: /app/httpd24
C compiler: gcc -std=gnu99
CFLAGS: -g -O2 -pthread
CPPFLAGS: -DLINUX -D_REENTRANT -D_GNU_SOURCE
LDFLAGS:
LIBS:
C preprocessor: gcc -E
此时，为了避免冲突，我们把本机yum安装的httpd卸载，不然都走80端口会冲突。
[root@centos7 httpd-2.4.38]#cd /app/
[root@centos7 app]#ls
httpd24
[root@centos7 app]#cd httpd24/
[root@centos7 httpd24]#ls
bin build cgi-bin conf error htdocs icons include lib logs man manual modules
[root@centos7 httpd24]#ls bin/
ab apr-1-config apxs dbmmanage envvars-std htcacheclean htdigest httpd:主配置文件 logresolve
apachectl：系统启动文件 apu-1-config checkgid envvars fcgistarter htdbm htpasswd httxt2dbm rotatelogs
5、[root@centos7 httpd24]#vim /etc/profile.d/env.sh 将变量写入文件
PS1="[\e[1;32m][\u@\h \W]\$[\e[0m]"
PATH=/app/httpd24/bin:$PATH
[root@centos7 httpd24]#. /etc/profile.d/env.sh
[root@centos7 httpd24]#echo $PATH
/app/httpd24/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
6、尝试启动：[root@centos7 httpd24]#apachectl
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using centos7.localdomain. Set the 'ServerName' directive globally to suppress this message
[root@centos7 ~]#ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 :::80 :::*
7、因为配置已经写入文件中
[root@centos7 ~]#cd /app/httpd24/htdocs/
[root@centos7 htdocs]#ls
index.html
[root@centos7 htdocs]#cat index.html
<html><body>It works!</body></html>
8、此时在进程中显示是demon服务，我们要把它改为Apache服务：修改文件
[root@centos7 httpd24]#ls
bin build cgi-bin conf error htdocs icons include lib logs man manual modules
[root@centos7 httpd24]#cd conf
[root@centos7 conf]#ls
extra httpd.conf magic mime.types original
[root@centos7 conf]#vim httpd.conf
User apache
Group apache
[root@centos7 conf]#apachectl restart
[root@centos7 conf]#ps aux

apache 58165 0.0 0.1 101620 1924 ? S 14:33 0:00 /app/httpd24/bin/httpd
9、[root@centos7 conf]#cd /etc/init.d/
[root@centos7 init.d]#ls
functions netconsole network README
[root@centos7 init.d]#vim /etc/rc.local
/app/httpd24/bin/apachectl
[root@centos7 init.d]#ll /etc/rc.d/rc.local

实验：编译实现基于FASTCGI的LAMP的wordpress
准备环境，两台主机，100做httpd+php,150做mariadb
1、将安装包rz到主机：[root@100 ~]#ls
httpd-2.4.37.tar.bz2 apr-1.6.5.tar.bz2 mariadb-10.2.15-linux-x86_64.tar.gz apr-util-1.6.1.tar.bz2 php-7.3.2.tar.xz wordpress-5.0-zh_CN.zip
[root@100 ~]#tar xf apr-1.6.5.tar.bz2
[root@100 ~]#tar xf httpd-2.4.37.tar.bz2
[root@100 ~]#tar xf php-7.3.2.tar.xz
[root@100 ~]#tar xf apr-util-1.6.1.tar.bz2
2、100主机上：mv apr-1.6.5 httpd-2.4.37/srclib/apr
mv apr-util-1.6.1 httpd-2.4.37/srclib/apr-util
3、一、cd httpd-2.4.37/
二、yum install gcc glibc pcre-devel openssl-devel expat-devel libxml2-devel bzip2-devel libmcrypt-devel
三、./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork --with-included-apr
四、make -j 4 && make install
4、[root@100 httpd-2.4.37]#echo 'PATH=/app/httpd24/bin:$PATH' > /etc/profile.d/lamp.sh
[root@100 httpd-2.4.37]#. /etc/profile.d/lamp.sh
5、useradd -r -s /sbin/nologin apache
[root@centos7 httpd-2.4.37]#vim /app/httpd24/conf/httpd.conf 此项修改不是必须，主要为了方便查看
User apache
Group apache
6、[root@100 httpd-2.4.37]#apachectl
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 0.0.0.100. Set the 'ServerName' directive globally to suppress this message
[root@100 httpd-2.4.37]#ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 :::80 :::*
7、现在我们去centos6上测试：[root@centos6 ~]#curl 192.168.141.100
<html><body>It works!</body></html> 此时说明Apache已经安装成功。
8、150主机上：tar xvf mariadb-10.2.15-linux-x86_64.tar.gz -C /usr/local/
[root@centos7 ~]#cd /usr/local

OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:
'./bin/mysqladmin' -u root password 'new-password'
'./bin/mysqladmin' -u root -h centos7.localdomain password 'new-password'
Alternatively you can run:
'./bin/mysql_secure_installation'
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.
You can start the MariaDB daemon with:
cd '.' ; ./bin/mysqld_safe --datadir='/data/mysql'
You can test the MariaDB daemon with mysql-test-run.pl
cd './mysql-test' ; perl mysql-test-run.pl
Please report any problems at http://mariadb.org/jira
The latest information about MariaDB is available at http://mariadb.org/.

现在我们去访问页面：
实验：编译实现基于FASTCGI的LAMP的wordpress
基于模块方式安装使用php
1、yum install php
[root@centos7 ~]#cd /var/www/html
[root@centos7 html]#ls
admin a.txt hello.sh index.html setcookie.php test.html
[root@centos7 html]#vim index.php
<?php
echo date("Y/m/d H:i:s");
phpinfo();
?> 下图为动态页面：
[root@centos7 html]#yum install php-mysql 要连数据库就要下载该包
3、yum install mariadb-server
[root@centos7 html]#systemctl restart mariadb
4、[root@centos7 html]#mysql_secure_installation 安全加固脚本
5、[root@centos7 html]#vim mysql.php
<?php
try {
$user='root';
$pass='123gxy';
$dbh= new PDO('mysql:host=localhost;dbname=mysql', $user, $pass);
foreach($dbh->query('SELECT user,host from user') as $row) {
print_r($row);
}
$dbh = null;
} catch (PDOException$e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
?>
[root@centos7 html]#systemctl restart mariadb
6、[root@centos7 ~]#mysql -uroot -p123gxy
MariaDB [(none)]> select user,host from mysql.user;
+------+-----------+
| user | host |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1 |
| root | localhost |
+------+-----------+
3 rows in set (0.00 sec)
此时这个实验就做完了。
实验：php使用PDO扩展连接数据库
将压缩包传到主机并压缩：
tar xvf phpMyAdmin-4.0.10.20-all-languages.tar.xz
[root@centos7 ~]#cd phpMyAdmin-4.0.10.20-all-languages
[root@centos7 phpMyAdmin-4.0.10.20-all-languages]#pwd
/root/phpMyAdmin-4.0.10.20-all-languages
[root@centos7 phpMyAdmin-4.0.10.20-all-languages]#cd ..
[root@centos7 ~]#ls
！ hellodb_innodb.sql phpMyAdmin-4.0.10.20-all-languages
anaconda-ks.cfg initial-setup-ks.cfg phpMyAdmin-4.0.10.20-all-languages.tar.xz
[root@centos7 ~]#mv phpMyAdmin-4.0.10.20-all-languages /var/www/html/pma
[root@centos7 ~]#cd /var/www/html/pma
[root@centos7 pma]#yum install php-mbstring 安装这个辅助工具
[root@centos7 pma]#cp config.sample.inc.php config.inc.php
[root@centos7 pma]#vim config.inc.php 此项是修改默认密码，基于安全。
$cfg['blowfish_secret'] = '123gxy'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
[root@centos7 pma]#systemctl restart httpd
登陆用户及密码即可进入图形化界面：
这时我们已经创建了用户如下：
[root@centos7 ~]#mysql -uwpuser -p123gxy -h192.168.141.200.
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| wordpress |该用户已经被创建成功。
+--------------------+
2 rows in set (0.00 sec) 该实验完成。在网站上访问及在mysql数据库查询结果一致。
实验：部署wordpress
将下载的软件包传到主机并解压 tar xvf wordpress-5.0.3-zh_CN.tar.gz [root@centos7 ~]#cd wordpress/ [root@centos7 wordpress]#ls index.php wp-activate.php wp-comments-post.php wp-cron.php wp-load.php wp-settings.php xmlrpc.php license.txt wp-admin wp-config-sample.php wp-includes wp-login.php wp-signup.php readme.html wp-blog-header.php wp-content wp-links-opml.php wp-mail.php wp-trackback.php [root@centos7 wordpress]#cp wp-config-sample.php wp-config.php [root@centos7 wordpress]#vim wp-config.php /** WordPress数据库的名称 */ define('DB_NAME', 'wordpress');
/** MySQL数据库用户名 */ define('DB_USER', 'wpuser');
/** MySQL数据库密码 */ define('DB_PASSWORD', '123gxy');
/** MySQL主机 */
define('DB_HOST', '192.168.141.200');
[root@centos7 ~]#mv wordpress /var/www/html/
[root@centos7 ~]#cd /var/www/html/
[root@centos7 html]#ls
admin pma setcookie.php wordpress
下面我们去网站登录：
成功登陆后的后台页面：我们就可以自建博客了：
实验：源码编译php.fpm
1、[root@centos7 ~]#ls
httpd-2.4.37.tar.bz2 apr-util-1.6.1.tar.bz2 apr-1.6.5.tar.bz2
[root@centos7 ~]#mv httpd-2.4.38.tar.bz2 apr-* /data/
[root@centos7 ~]#cd /data/
[root@centos7 data]#ls
apr-1.6.5.tar.bz2 apr-util-1.6.1.tar.bz2 httpd-2.4.38.tar.bz2
tar xvf xxxx 将其三个包解压：
root@centos7 data]#ls
apr-1.6.5 apr-util-1.6.1 httpd-2.4.38 apr-1.6.5.tar.bz2 apr-util-1.6.1.tar.bz2 httpd-2.4.38.tar.bz2
[root@centos7 data]#mv apr-1.6.5 httpd-2.4.38/srclib/apr
[root@centos7 data]#mv apr-util-1.6.1 httpd-2.4.38/srclib/apr-util
2、[root@centos7 httpd-2.4.38]#1、yum install gcc glibc pcre-devel openssl-devel expat-devel 安装必要包
[root@centos7 httpd-2.4.38]#./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-included-apr --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork
