LNMPUbuntu
通常我们使用centos来组建LNMP,但是我们开发时多使用ubuntu的桌面版本来调试,下面将详细介绍如何在ubuntu上安装一套LNMP。
一、下载并安装最新的ubuntu14.04桌面版本
二、安装mysql
1. 下载mysql的最新版本,例如:
wgethttp://dl.mysql.cn/mysql5/5.5/mysql-5.5.25.tar.gz
2. 解压缩:
tar -xvf mysql-5.5.25.tar.gz
3. 进入mysql文件目录:
cd mysql-5.5.25
注意:文件INSTALL-SOURCE中有安装指南,可以参考。
4. mysql需要用cmake编译,先安装cmake:
sudo apt-get install cmake
5. 安装g++编译器
sudo apt-get install g++
6. 安装依赖库libncurses
sudo apt-get install libncurses5-dev
7. 使用下面的命令开始编译并安装,如果cmake失败了,重新调用cmake命令前,需要先删除文件CMakeCache.txt
cmake .
make
sudo make install
8. 增加mysql组和用户
groupadd mysql
useradd -r -g mysql mysql
9. 进入mysql的安装目录
cd /usr/local/mysql
10. 改变owner和group
sudo chown -R mysql .
sudo chgrp -R mysql .
11. 创建数据库
sudo scripts/mysql_install_db --user=mysql
12. 改变owner
sudo chown -R root .
sudo chown -R mysql data
13. 生成mysql的配置文件
sudo cp support-files/my-medium.cnf /etc/my.cnf
14. 启动mysql
sudo bin/mysqld_safe --user=mysql &
15. 执行下面命令可以启动mysql的命令行工具,如果能正确启动说明mysql安装成功。
/usr/local/mysql/bin/mysql
二、安装PHP
1. 下载PHP源码包:
wgethttp://cn2.php.net/distributions/php-5.5.12.tar.gz
2. 解压缩:
tar -xvf php-5.5.12.tar.gz
3. 安装依赖库
sudo apt-get install libxml2-dev openssl libcurl3-openssl-dev libcurl4-gnutls-dev libjpeg-dev libpng-dev libxpm-dev libfreetype6-dev libt1-dev libmcrypt-dev libxslt1-dev
4. 进入源码目录
cd php-5.5.12
5. 执行配置命令
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --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-zip --enable-soap --without-pear --with-zlib --enable-pdo --with-pdo-mysql
7. 编译前运行下面的命令
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/
8. 编译并安装
make
sudo make install
9. 生成php的配置文件php.ini
sudo cp ./php.ini-production /usr/local/php/etc/php.ini
10. 启动php
/usr/local/php/bin/php-cgi -b 9000&
三、安装Nginx
1. 下载Nginx源码包:
wgethttp://nginx.org/download/nginx-1.7.0.tar.gz
2. 解压缩
tar -xvf nginx-1.7.0.tar.gz
3. 安装依赖库
sudo apt-get install libpcre3 libpcre3-dev
4. 进入源码目录
cd nginx-1.7.0
5. 运行配置命令
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module
6. 编译并安装
make
sudo make install
7. 修改nginx的配置文件:
sudo gedit /usr/local/nginx/conf/nginx.conf&
8. 在文件中找到下面的内容,并将前面的#号取掉。
location ~ /.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
注意:上面的fastcgi_param参数要写成"$document_root$fastcgi_script_name;"。
9. 启动nginx
sudo /usr/local/nginx/sbin/nginx&
四、测试nginx,php和mysql的连接
1. 在浏览器里输入127.0.0.1看看是否出现nginx的提示
2. 在/usr/local/nginx/html目录下新建一个index.php文件,加入下面一行
3. 改变index.php的属性
sudo chmod ugo+rwx -R /usr/local/nginx/html/index.php
4. 在浏览器里输入127.0.0.1/index.php看看是否出现php的信息
5. 最后测试php和mysql的连接情况,把index.php中的内容换成以下内容:
$con = mysql_connect("127.0.0.1","root",null);
mysql_select_db("information_schema", $con);
$result = mysql_query("SELECT * FROM USER_PRIVILEGES");
$row = mysql_fetch_row($result);
echo $row[0];
mysql_close($con);
?>
6. 在浏览器里输入127.0.0.1/index.php,出现下面的信息表示nginx,php和mysql间连接正常
'root'@'localhost

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.

MySQL is not a programming language, but its query language SQL has the characteristics of a programming language: 1. SQL supports conditional judgment, loops and variable operations; 2. Through stored procedures, triggers and functions, users can perform complex logical operations in the database.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is an open source relational database management system suitable for data storage, management, query and security. 1. It supports a variety of operating systems and is widely used in Web applications and other fields. 2. Through the client-server architecture and different storage engines, MySQL processes data efficiently. 3. Basic usage includes creating databases and tables, inserting, querying and updating data. 4. Advanced usage involves complex queries and stored procedures. 5. Common errors can be debugged through the EXPLAIN statement. 6. Performance optimization includes the rational use of indexes and optimized query statements.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

InnoDB's lock mechanisms include shared locks, exclusive locks, intention locks, record locks, gap locks and next key locks. 1. Shared lock allows transactions to read data without preventing other transactions from reading. 2. Exclusive lock prevents other transactions from reading and modifying data. 3. Intention lock optimizes lock efficiency. 4. Record lock lock index record. 5. Gap lock locks index recording gap. 6. The next key lock is a combination of record lock and gap lock to ensure data consistency.
