Nine. LNMP website architecture practice deployment

Interim Cluster Architecture - Chapter 9 - Interim Architecture LNMP Chapter
========================================= =================================

01. LNMP architecture description
1) Connect front-end web services and back-end storage services in series
2) Mainly realize processing dynamic requests of PHP programs

02. LNMP architecture works
L--Linux N--nginx M--mysql P--php

03. LNMP architecture deployment

1) Install LNMP related software 1. The basic optimization operation of deploying the Linux system must be completed (the firewall is closed and the selinux /tmp permission is 1777)

② . Deploy the nginx service and
ignore it for the time being ③. Deploy the mysql service andyum deploy the software

Compile and install software

Deploy mysql service by binary package
The first mileage : Download and unzip the mysql software program
mysql official download link address: ftp://ftp.jaist.ac.jp/pub/mysql/Downloads/MySQL-5.6/Upload the
mysql software program, Upload using xftp software
tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.6.34-linux-glibc2.5-x86_64 /application/mysql-5.6.34

second Mileage : Create a software program soft link
ln -sf /application/mysql-5.6.34/ /application/mysql
If the soft link already exists -f Force creation
The third mileage : Create a database management user and authorize the data directory useradd mysql -M -s /sbin/nologin chown -R mysql.mysql /application/mysql/data/ Fourth Mile : Initialize the database service /application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/ application/mysql/data/ --user=mysql

Which database is basedir to initialize, and later learn how to deploy several databases in a system, so you need to specify

datadir specifies the data directory user specifies the database directory management account

Fifth mile : start mysql service cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld

mysql.server startup script file Copy the file to the startup startup folder

sed -ri 's#/usr/local#/application#g' /etc/init.d/mysqld /application/mysql/bin/mysqld_safe

vim mysql.server sees that the default basedir is not in the application we created and needs to be modified

vim mysqld_safe command to control whether the mysql service can be started normally See the program directory recognized by default

Also not /application needs to be modified

cp /application/mysql/support-files/my-default.cnf /etc/my.cnf

The mysql configuration file that comes with the /etc/my.cnf system may not match our version

The configuration file in cp mysql is in the past

Finally start mysql /etc/init.d/mysqld start

The sixth mileage : set the database root user login password
set the password /application/mysql/bin/mysqladmin -uroot password "oldboy123"
login /application/mysql/bin/mysql -uroot -poldboy123
to enter the database All operations are using sql statement

show databases; 显示所有的数据库内容

④. PHP软件安装部署过程
第一里程：解决PHP软件的依赖关系
yum install -y zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel

libiconv软件安装---字符集转换库(默认可以不进行安装了)
cd /server/tools
#wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar zxf libiconv-1.14.tar.gz 解压
cd libiconv-1.14 进入
./configure --prefix=/usr/local/libiconv 配置
make
make install
cd ../

#wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

部署repo源之前已经操作过了
yum -y install libmcrypt-devel mhash mcrypt 加密相关软件
rpm -qa libmcrypt-devel mhash mcrypt

第二个里程：下载解压PHP软件
php官方网站下载：php.net
cd /server/tools/
tar xf php-5.5.32.tar.gz
cd php-5.5.32 进入目录配置php 不需要区了解每个配置的类容

以下配置方法是汇总实际工作的一个配置
./configure \
--prefix=/application/php-5.5.32 \
--with-mysql=/application/mysql-5.6.34 \
--with-pdo-mysql=mysqlnd \
--with-iconv-dir=/usr/local/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-mcrypt \
--with-gd \
--enable-gd-native-ttf \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-soap \
--enable-short-tags \
--enable-static \
--with-xsl \
--with-fpm-user=www \
--with-fpm-group=www \
--enable-ftp \
--enable-opcache=no

配置成功

##防错(以下信息可以不进行配置了)
ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/

touch ext/phar/phar.phar

/server/tools/php-5.5.32/ext/phar/phar.phar
make
make install
ln -s /application/php-5.5.32/ /application/php

第三个里程：设置PHP程序配置文件
php.ini php-fpm.ini两个配置文件

php.ini 放在安装包里面
cp php.ini-production /application/php-5.5.32/lib/

一下命令是因为创建了软链接

cd /application/php/etc/

里面有个php-fpm.conf.default 备份文件程序不能加载

所以备份重命名
cp php-fpm.conf.default php-fpm.conf

第四个里程：启动php程序服务
/application/php/sbin/php-fpm
netstat -lntup|grep php

添加到、vim /etc/rc.local 开机自动开启
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 6251/php-fpm

2）进行软件直接的结合
nginx与php结合：编写nginx配置文件
location ~* .*\.(php|php5)?$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
以上匹配到php或php5的都给9000端口，默认使用这个配置即可不用过多关注

然后重启

测试

cd /application/nginx/html/blog/ 进入blog站点目录

\rm ./* -fr清空里面的类容

vim test_info.php编写php的测试网页

http://blog.etiantian.org/test_info.php 浏览器打开

动态解析成功！

php与mysql结合：编写php程序代码

编写生成到相应站点目录下如 /application/nginx/html/blog

# vim test_mysql.php
<?php
//$link_id=mysql_connect('主机名','用户','密码');
//mysql -u用户 -p密码 -h 主机
$link_id=mysql_connect('localhost','root','oldboy123') or mysql_error();
if($link_id){
echo "mysql successful by oldboy !\n";
}else{
echo mysql_error();
}
?>

解释：

$link_id=mysql_connect 设置变量=调用了一个php调用mysql的函数

localhost---mysql服务器在哪哪儿登陆过去的这里设置的本地

root---登陆数据库的用户后面为密码

if判断如果成功则显示 echo " "

如果失败echo 就调用or后面的mysql_error()函数

==========================================
测试浏览器打开http://blog.etiantian.org/test_mysql.php

显示

结合成功！

3）部署一个真的网站
第一个里程：下载与上传网站代码

wordpress-4.7.3-zh_CN.tar.gz 一个开源的博客网站代码

第二个里程：解压程序代码，将程序代码保存到站点目录并进行授权
tar xf wordpress-4.7.3-zh_CN.tar.gz
mv wordpress/* /application/nginx/html/blog/

移动过去的文件很多都是nobody的权限，需要修改

修改成nginx: worker进程的用户
