LNMP架构部署

 LNMP架构部署

 

LNMP源码安装

 

源码包版本

nginx-0.7.65

pcre-8.02

mysql-5.1.53-linux-i686-glibc23.tar.gz

php-5.2.13.tar.gz

php-5.2.13-fpm-0.5.13.diff.gz

 

下载软件包到/bak/software目录下

 

 

1.安装ngxin

安装nginx之前，确保系统已经安装了gcc、openssl-devel、pcre-devel和zlib-devel软件库

 

 

安装nginx所需的pcre-devel库

tar zxvf pcre-8.02.tar.gz

cd pcre-8.02

./configure

make

make install

 

tar zxvf nginx-0.7.65.tar.gz

cd nginx-0.7.65

./configure --prefix=/opt/nginx  --with-http_stub_status_module --with-http_gzip_static_module --without-http_rewrite_module  --with-pcre=/bak/software/pcre-8.02

make

make install

 

 

 

 

2.安装mysql免安装版

 

2.1、新建 mysql 组和用户；

groupadd mysql

useradd -g mysql mysql

 

2.2、用 root 用户给 mysql 安装路径授权，依次执行：

MYSQL_BASE=/opt/mysql

mkdir -p $MYSQL_BASE/mysqldata/mysqllog

mkdir -p /var/run/mysqld/

chmod -R 777 $MYSQL_BASE

chown -R mysql:mysql $MYSQL_BASE

chown -R mysql:mysql /var/run/mysqld/

注：以上路径是我准备安装 mysql 的路径，部分路径与实际环境相关

 

2.3、切换到mysql 用户，设置 mysql 用户环境变量：编辑 /home/mysql/.bash_profile 文件，增加如下内容：

su - mysql

vim .bash_profile

export MYSQL_BASE=/opt/mysql

export DATADIR=$MYSQL_BASE/mysqldata

export LD_LIBRARY_PATH=$BASEDIR/lib:/lib:/usr/lib:/usr/local/lib

export TMPDIR=/tmp

export PATH=$PATH:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin

export PATH=$PATH:$BASEDIR/bin:$MYSQL_BASE:$BASEDIR:$LD_LIBRARY_PATH

 

 

2.4、将安装包解压到/opt/mysql目录下，依次执行：

cd /bak/software

tar zxvf  mysql-5.1.53-linux-i686-glibc23.tar.gz -C /opt/mysql

 

2.5、开始安装 mysql：

1) 执行：

cd /opt/mysql

./scripts/mysql_install_db --basedir=$BASEDIR --datadir=$DATADIR --user=mysql

 

2) 切换到 root 用户， 依次执行：

su - root

cd /opt/mysql/

cp ./support-files/my-medium.cnf /etc/my.cnf 

cp ./support-files/mysql.server /etc/init.d/mysql

chkconfig --add mysql

chkconfig --level 345 mysql on

 

 

3) 编辑 /etc/my.cnf 文件，找到如下片段：

[mysqld]

port = 3306

socket = /tmp/mysql.sock

skip-locking

key_buffer_size = 16M

max_allowed_packet = 1M

table_open_cache = 64

sort_buffer_size = 512K

net_buffer_length = 8K

read_buffer_size = 256K

read_rnd_buffer_size = 512K

myisam_sort_buffer_size = 8M

 

在下面增加：

user = mysql

pid-file = /var/run/mysqld/mysqld.pid

basedir = /opt/mysql

datadir = /opt/mysql/mysqldata

lower_case_table_names = 1

innodb_additional_mem_pool_size = 16M

innodb_buffer_pool_size = 2G

innodb_data_file_path = ibdata1:1000M:autoextend

innodb_autoextend_increment = 64

innodb_file_per_table = 1

innodb_data_home_dir = /opt/mysql/mysqldata

innodb_file_io_threads = 4

innodb_thread_concurrency = 16

innodb_flush_log_at_trx_commit = 2

innodb_log_buffer_size = 8M

innodb_log_file_size = 512M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 40

innodb_lock_wait_timeout = 120

innodb_locks_unsafe_for_binlog = 1

innodb_autoinc_lock_mode = 2

 

修改 [client] 和 [mysqld] 下的 socket 那行为：

socket = /var/run/mysqld/mysqld.sock

注：Linux环境是区分大小写的，所以要加 lower_case_table_names = 1 这个配置

 

4) 启动mysql， 用 mysql 用户执行： /etc/init.d/mysql start 显示：

Starting MySQL........................................................[ 确定 ]

则表示启动成功。

 

 

5)设置数据库root用户密码：

/opt/mysql/bin/mysqladmin -u root password 'oracle'

/opt/mysql/bin/mysqladmin -u root -p -h localhost.localdomain password 'oracle'

 

 

 

3.安装php

安装php需要下面软件包的支持，如果没有安装，请自行安装

gcc gcc-c++ libxml2 libxml2-devel autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel zlib zlib-devel glibc 

glibc-devel glib2 glib2-devel

 

开始编译安装PHP和PHP-FPM

cd /bak/software

tar zxvf php-5.2.13.tar.gz

gzip -cd php-5.2.13-fpm-0.5.13.diff.gz | patch -d php-5.2.13 -p1

 

cd php-5.2.13

./configure --prefix=/opt/php --enable-fastcgi --enable-fpm --with-mysql=/opt/mysql

make

make install

cp php.ini-dist /opt/php/lib/php.ini

 

修改php-fpm.conf配置文件

vim /opt/php/etc/php-fpm.conf

将标签user和group地方注释到

nobody

nobody

 

启动PHP

/opt/php/sbin/php-fpm start

 

 

ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock

 

 

4.nginx与php整合

 

vim /opt/nginx/nginx.conf

 

#location ~ \.php$ {

        #    root           html;

        #    fastcgi_pass   127.0.0.1:9000;

        #    fastcgi_index  index.php;

        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

        #    include        fastcgi_params;

        #}

 

去掉注释

 

location ~ \.php$ {

            root           html;

            fastcgi_pass   127.0.0.1:9000;

            fastcgi_index  index.php;

            fastcgi_param  SCRIPT_FILENAME  /opt/nginx/html$fastcgi_script_name;

            include        fastcgi_params;

        }

 

启动nginx服务

/opt/nginx/sbin/nginx

 

 

 

 

 

5.php与nginx测试页、php连接mysql测试页

 

cd /opt/nginx/html

 

vim test.php

 

 

vim index.php

$link=mysql_connect(localhost,root,mysql);

if(!$link) echo "失败!"; else echo "成功!";

mysql_close();

?>
