编译安装lamp

整体规划图

共三台主机；httpd，php-fpm，mariadb分别位于不同主机。

二进制安装mariadb

安装过程大致思路为：准备二进制包—解压到指定文件后创建mysql连接方便管理—创建数据目录和著配置文件目录—安装mysql指定数据目录—开机自启配置

tar -zxvf  mariadb-5.5.43-linux-x86_64.tar.gz   -C /usr/local/
ln -s /usr/local/mariadb-5.5.43-linux-x86_64/ /usr/local/mysql 
useradd  -s /sbin/nologin  mysql
chown  -R root.mysql /usr/local/mysql/*
mkdir -p /mydata/data
chown -R mysql.mysql /mydata/data
mkdir /etc/mysql
cp -a /usr/local/mysql/support-files/my-large.cnf  /etc/mysql/my.cnf 
vim /etc/mysql/my.cnf
    [mysqld]###加三行，一定要配置在[mysqld]配置段否则mysql启动不起来。
    datadir =/mydata/data
    innodb_file_per_table = ON
    skip_name_resolve = ON
vim /etc/profile.d/mysql.sh
    export PATH=/usr/local/mysql/bin/:$PATH
source  /etc/profile.d/mysql.sh
cd /usr/local/mysql;scripts/mysql_install_db --user=mysql --datadir=/mydata/data 
cp -a  /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
chkconfig  --add mysqld 
/usr/local/mysql/bin/mysql_secure_installation

编译安装httpd-2.4

第一步：编译安装httpd

mkdir /app/httpd-2.4.39/srclib/apr-util
mkdir /app/httpd-2.4.39/srclib/apr
cp -r /app/apr-1.7.0/* /app/httpd-2.4.39/srclib/apr
cp -r /app/apr-util-1.6.1/* /app/httpd-2.4.39/srclib/apr-util/
cd /app/httpd-2.4.39/
./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

第二步：配置httpd

Httpd编译过程：

　　/app/httpd24/build/config.nice

自带的服务控制脚本：

　　/app/httpd24/bin/apachectl

导出环境变量

vim /etc/profile.d/httpd24.sh

　　export PATH=/app/httpd24/bin:$PATH

自定义启动脚本

/usr/lib/systemd/system/httpd24.service[Unit]
Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target
Documentation=man:httpd(8)
Documentation=man:apachectl(8)

[Service]
Type=forking
#Type=notify
#EnvironmentFile=/etc/sysconfig/httpd
ExecStart=/app/httpd24/bin/httpd $OPTIONS -k start
#ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND
ExecReload=/app/httpd24/bin/httpd $OPTIONS -k graceful
ExecStop=/bin/kill -WINCH ${MAINPID}
# We want systemd to give httpd some time to finish gracefully, but still want
# it to kill httpd after TimeoutStopSec if something went wrong during the
# graceful stop. Normally, Systemd sends SIGTERM signal right after the
# ExecStop, which would kill httpd. We are sending useless SIGCONT here to give
# httpd time to finish.
KillSignal=SIGCONT
PrivateTmp=true

[Install]
WantedBy=multi-user.target

重载配置

systemctl daemon-reload

启动服务

systemctl start httpd24

编译安装php

 第一步：安装php

yum -y install epel-release libxml2-devel bzip2-devel libmcrypt-devel  gcc pcre-devel openssl-devel expat-devel
tar -xvf php-7.3.5.tar.bz2 
./configure --prefix=/app/php \
--enable-mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-openssl \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--with-config-file-path=/etc \
--with-config-file-scan-dir=/etc/php.d \
--enable-mbstring \
--enable-xml \
--enable-sockets \
--enable-fpm \
--enable-maintainer-zts \
--disable-fileinfonstall
make && make install

第二步配置php

cp php.ini-production /etc/php.ini ##从php.ini-production生成php配置文件
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm###生成php启动文件
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm ###配置开机自启
chkconfig php-fpm on
vim /app/php/etc/php-fpm.d
　　listen = 9000 ###监听所有ip的9000段偶
vim /var/www/html/index.php ##提供简单的测试页。

<?php
　　echo date("Y/m/d H:i:s");  ###实践测试代码
　　$mysqli=new mysqli("192.168.206.30", "root", ""); ###下面时数据库测试代码
　　if(mysqli_connect_errno()){
　　　　echo "Failure";
　　$mysqli=null;
　　exit;
　　}
　　echo "OK";
　　$mysqli->close();
?>

第三步配置httpd支持php-fpm

vim /app/httpd24/conf/httpd.conf
取消下面两行的注释,开启proxy
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
修改下面行
<IfModule dir_module>
 DirectoryIndex index.php index.html
</IfModule>
加下面四行
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://192.168.206.20:9000/var/www/html/$1  ##将访问*.php的请求装发到20服务器的/var/www/html/*.php

第四步，启动服务

service php-fpm start

systemctl restart httpd24
