本次试验用了两个web，一个php和mysql web1，2 （172.16.31.30，31.31）nfs 172.16.31.34

php 172.16.31.32 mysql 172.16.31.32

构建如图所示

1，搭建web

首先# mount -t nfs 172.16.31.34:/mydata/mydata 挂载nfs

此次编译和上篇LAMP中web所用的版本是一个版本，编译步骤相同

1）下载apr-1.5.0.tar.bz2 apr-util-1.5.3.tar.bz2 httpd-2.4.9.tar.bz2 这三个包，依次解压，

# tar xf apr-1.5.0.tar.bz2

# cd apr-1.5.0

# ./configure --prefix=/usr/local/apr

# make && make install

2) 编译安装apr-util

# tar xf apr-util-1.5.3.tar.bz2

# cd apr-util-1.5.3

# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr

# make && make install

3）编译安装httpd-2.4.9

# tar xf httpd-2.4.9.tar.bz2

# cd httpd-2.4.9

# ./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modules=most --enable-mpms-shared=all --with-mpm=event

# make && make install

两台都是做如此操作，然后修改PATH环境变量

echo "export PATH=/usr/local/apach/bin:$PATH">> /etc/profile.d/httpd.sh

让PATH在当前shell生效并且启动服务

source /etc/profile.d/httpd.sh

apachectl start

# vim /etc/httpd/httpd.con

LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so 需启用的两个模块

LoadModule proxy_module modules/mod_proxy.so

ServerName www.caoshujia.com:80

ProxyRequests off 关闭正向代理

ProxyPassMatch ^/(.*\.php)$ fcgi://172.16.2.11:9000/mydata/$1 只要是php文件都使用fcgi协议代理到php服务器。

DocumentRoot "/mydata/" 修改站点根目录为nfs

<Directory "/mydata/"> 修改对站点根目录的控制标签

DirectoryIndex index.html index.php 添加默认请求文件

AddType application/x-httpd-php .php 在<IfModule mime_module>标签中加入，以支持php格式的文件。

AddType application/x-httpd-php-source .phps

# httpd -t

# apache restart

2 php编译安装

1）事先需要安装几个包组，如果安装，无需安装

# yum -y groupinstall "Desktop Platform Development"

# yum -y install bzip2-devel

# yum -y install libmcrypt-devel

2）编译安装

# tar xf php-5.4.26.tar.bz2

# cd php-5.4.26

#./configure --prefix=/usr/local/php --with-mysql --with-mysqli --with-openssl --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --enable-sockets --enable-fpm --with-bz2 --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-mcrypt

# make && make install

3）为php提供配置文件：

# cp php.ini-production /etc/php.ini

4）配置php-fpm

为php-fpm提供SysV init脚本，并将其添加至服务列表：

# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm

# chmod +x /etc/rc.d/init.d/php-fpm

# chkconfig --add php-fpm

# chkconfig php-fpm on

为php-fpm提供配置文件：

# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

编辑php-fpm的配置文件：

# vim /usr/local/php/etc/php-fpm.conf

配置fpm的相关选项为你所需要的值，并启用pid文件（如下最后一行）：

pm.max_children = 50

pm.start_servers = 5

pm.min_spare_servers = 2

pm.max_spare_servers = 8

pid = /usr/local/php/var/run/php-fpm.pid

指定php的PID文件所在位置。这条一定要写在[global]下面第一行，不然不会生效。

接下来就可以启动php-fpm了：

# service php-fpm start

检测监听端口

# netstat -tnlp | grep php-fpm

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 689/php-fpm

[root@localhost php-5.4.26]# service php start

[root@localhost php-5.4.26]# mkdir /mydata

[root@localhost php-5.4.26]# mount -t nfs 172.16.31.34:/mydata/mydata 挂载nfs，用来存储php页面。

[root@localhost php-5.4.26]# chown -R nobody /mydata 修改webdata目录的所有者为nobody， 因为nobody是php进程运行的用户。

3，mysql配置

1首先下载mysql-5.5.33包组（mariadb-5.5.36-linux-x86_64.tar.gz），然后解压mariadb-5.5.36-linux-x86_64.tar.gz到/usr/local

[root@localhost ~]# tar xfmariadb-5.5.36-linux-x86_64.tar.gz -C /usr/local

2 准备数据存放的文件系统

a 新建一个sda3

[root@localhost~]# fdisk /dev/sda

Command (m for help): n

Commandaction

eextended

b读入磁盘中

[root@localhost ~]# kpartx -af /dev/sda

device-mapper: reload ioctl on sda1failed: Invalid argument

create/reload failed on sda1

device-mapper: reload ioctl on sda2failed: Invalid argument

[root@localhost ~]# partx -a /dev/sda

BLKPG: Device or resource busy

error adding partition 1

BLKPG: Device or resource busy

error adding partition 2

BLKPG: Device or resource busy

error adding partition 3 （表示已经读入到磁盘中）

c 新建逻辑卷，并将其挂载至特定目录，此处目录设置为/mydata

[root@localhost ~]# pvcreate /dev/sda3

Physical volume "/dev/sda3" successfully created

[root@localhost ~]# vgcreate myvg/dev/sda3

Volume group "myvg" successfully created

[root@localhost ~]# lvcreate -L 10G -nmydata myvg

Logical volume "mydata" created

[root@localhost ~]# mke2fs -t ext4 -LMYDATA -b 4096 -m 3 /dev/myvg/mydata

并且能开机挂载，编辑fastab文件

/dev/mapper/vg0-root / ext4 defaults 1 1

UUID=90ebd4cf-95c1-4338-b0dd-19b2b1cb943d/boot ext4 defaults 1 2

/dev/mapper/vg0-usr /usr ext4 defaults 1 2

/dev/mapper/vg0-var /var ext4 defaults 1 2

/dev/mapper/vg0-swap swap swap defaults 0 0

tmpfs /dev/shm tmpfs defaults 0 0

devpts /dev/pts devpts gid=5,mode=620 0 0

sysfs /sys sysfs defaults 0 0

proc /proc proc defaults 0 0

LABEL=MYDATA /mydata ext4 defaults 0 0

（开机挂载）

d新建用户以安全方式运行进程，并创建链接

[root@localhost ~]# groupadd -r mysql

[root@localhost ~]# useradd-g mysql -r mysql

[root@localhost ~]# idmysql

uid=496(mysql)gid=493(mysql) groups=493(mysql)

[root@localhost ~]#chown -R mysql.mysql /mydata/data/

[root@localhost ~]# ll -a/mydata/data/

total 8

drwxr-xr-x 2 mysql mysql4096 Aug 11 20:15 .

先进入/usr/local目录下

[root@localhost local]# ln-sv mariadb-5.5.36-linux-x86_64 mysql

lrwxrwxrwx1 root root 27 Aug 11 20:18mysql -> mariadb-5.5.36-linux-x86_64

e为mysql提供主配置文件

cd/usr/local/mysql/

mkdir /etc/mysql创建一个目录，因为在/etc下有个my.cnf

cpsupport-files/my-large.cnf/etc/mysql/my.cnf

vim/etc/mysql/my.cnf

port = 3306

socket =/tmp/mysql.sock

skip-external-locking

key_buffer_size = 256M

max_allowed_packet = 1M

table_open_cache = 256

sort_buffer_size = 1M

read_buffer_size = 1M

read_rnd_buffer_size = 4M

myisam_sort_buffer_size = 64M

thread_cache_size = 8

query_cache_size= 16M

# Try number of CPU's*2 for thread_concurrency

thread_concurrency = 8

datadir = /mydata/data （指定mysql数据文件的存放位置）

开始初始化

[root@localhostmysql]# scripts/mysql_install_db --user=mysql --datadir=/mydata/data/

（此处必须在 mysql 目录下，要在scripts初始化，会报错）

f 为mysql提供sysv服务脚本

[root@localhostmysql]# cp support-files/mysql.server/etc/rc.d/init.d/mysqld

然后添加到服务列表中

[root@localhost mysql]# chkconfig --addmysqld

[root@localhost mysql]# chkconfig--list mysqld

mysqld 0:off1:off2:on3:on4:on5:on6:off

启动服务

root@localhost mysql]# service mysqld start

Starting MySQL...[ OK ]

[root@localhost mysql]# ss -tnl

设置权限

[root@localhostmysql]#chmod +x /etc/rc.d/init.d/mysqld

g 编辑环境变量

[root@localhost~]# vim /etc/profile.d/mysql.sh

exportPATH=/usr/local/mysql/bin:$PATH

h导出头文件和库文件

ln -sv /usr/local/mysql/include /usr/include/mysql

[root@localhost~]# vim /etc/ld.so.conf.d/mysql.conf （新建）

/usr/local/mysql/lib

让系统重新载入

[root@localhost ~]#ldconfig -v | grep mysql

/usr/local/mysql/lib:

libmysqld.so.18 -> libmysqld.so.18

libmysqlclient.so.18 ->libmysqlclient_r.so.18.0.0

/usr/lib64/mysql:

libmysqlclient.so.16 -> libmysqlclient.so.16.0.0

libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0

[root@localhost ~]#mysql

MariaDB [(none)]> use mysql

MariaDB [mysql]> grant all on discuz.* to disadmin@172.16.31.32 identified by 'root'; 为数据库用户disadmin授权在172.16.31.32主机上登陆，密码为 root

配置完成。
