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:

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

./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
