源码安装 php+nginx 构建BBS平台 (以CentOS6为例)

原创 服务器

第一：安装前准备

1， 说明：

php 和 nginx 使用源码安装，便于升级。mysql使用yum安装。其它的一些支持组件、库使用yum安装

2， 本文的系统环境

[root@localhost ~]# # uname -a
Linux localhost.localdomain 2.6.32-220.17.1.el6.x86_64 #1 SMP Wed May 16 00:01:37 BST 2012 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# # more /etc/redhat-release
CentOS Linux release 6.2 (Final)

3， 本文所需软件

epel-release-6-7.noarch.rpm yum 源
nginx-1.2.0.tar.gz 最新稳定版 官网可下载
php-5.4.3.tar.gz 最新稳定版 官网可下载

4， 下载yum源并安装

[root@localhost ~]# wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm
[root@localhost ~]#
[root@localhost ~]# rpm -ivh epel-release-6-7.noarch.rpm
[root@localhost ~]# yum install gcc make pcre-devel pcre

5， 创建相关目录和用户名

[root@localhost ~]# mkdir -pv /opt/wwwroot/bbs.jedy.com
[root@localhost ~]# useradd nginx

 第二：PHP的安装和配置：

1， 安装php所需的库文件

 

[root@localhost ~]# yum install libjpeg-6b libjpeg-devel libpng libpng-devel zlib zlib-devel freetype freetype-devel libXpm libXpm-devel libxml2 libxml2-devel bzip2 bzip2-devel gd

2， 源码安装php

从php-5.3.2开始，php 已自带了php-fpm 补丁，不需再另装
[root@localhost ~]# tar zxvf php-5.4.3.tar.gz -C /usr/local/src
[root@localhost ~]# cd /usr/local/src/php-5.4.3/
[root@localhost php-5.4.3]# ./configure --prefix=/usr/local/php-5.4.3 --with-mysql --enable-fastcgi --enable-fpm --enable-mbstring --with-bz2 --with-freetype-dir --with-png-dir --with-xpm-dir --enable-gd-native-ttf --with-t1lib --without-gdbm --with-gettext --with-iconv --with-jpeg-dir --with-pcre-regex --with-zlib --enable-exif --enable-ftp --enable-magic-quotes --enable-sockets --with-libxml-dir --enable-xml --with-mhash --without-gd
\\ --enable-fastcgi --enable-fpm 这两个参数一定要加上 要不然 php 不能以 fastcgi方式运行，nginx也就不能连接了
\\ --enable-fastcgi 会报错 不用理
[root@localhost php-5.4.3]# make && make install
[root@localhost php-5.4.3]# ln -sv /usr/local/php-5.4.3 /usr/local/php
[root@localhost php-5.4.3]# cp /usr/local/src/php-5.4.3/php.ini-development /usr/local/php/etc/php.ini
[root@localhost php-5.4.3]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@localhost php-5.4.3]# cd /usr/local/php/

 

3， 编辑配置文件

[root@localhost php]# vi etc/php.ini
改 short_open_tag = Off 为
short_open_tag = On \\ 改了这个之后才能支持 <? ?> 这种标签，这个和php-5.3 之前的版本的不同之处，改了这个之后我们才能进行下一步的测试。如果不改的话，会造成访问php网页时不出现任何页面，但也不报错
[root@localhost php]# vim /usr/local/php/etc/php-fpm.conf
将user和group 都改成nginx 让php 以 nginx用户运行
并确保有以下这一行
listen = 127.0.0.1:9000
[root@localhost php]# /usr/local/php/sbin/php-fpm -c /usr/local/php/php.ini
[root@localhost php]# echo “/usr/local/php/sbin/php-fpm -c /usr/local/php/php.iniservice” &gt;&gt;/etc/rc.local

 

第三： NGINX的安装和配置：
1， 源码安装nginx

   [root@localhost ~]# tar zxvf /root/nginx-1.2.0.tar.gz -C /usr/local/src
[root@localhost ~]# cd /usr/local/src/nginx-1.2.0/
[root@localhost nginx-1.2.0]# ./configure --prefix=/usr/local/nginx-1.2.0 --conf-path=/etc/nginx/nginx.conf --with-http_stub_status_module --witho
ut-http_rewrite_module --with-pcre
[root@localhost nginx-1.2.0]# make && make install
[root@localhost nginx-1.2.0]# ln -sv /usr/local/nginx-1.2.0 /usr/local/nginx
[root@localhost nginx-1.2.0]# mv /etc/nginx/nginx.conf.default /etc/nginx/nginx.conf
[root@localhost nginx-1.2.0]# cp /usr/local/nginx/* /opt/wwwroot/bbs.jedy.com/
[root@localhost nginx-1.2.0]# cd

 

2， 编辑配置文件

[root@localhost ~]# vim /etc/nginx/nginx.conf 修改以下内容
server { \\禁止ip地址访问
server_name _; #default
return 404;
}
server { \\ 允许域名访问
limit_conn addr 10;
listen 80 ;
server_name bbs.jedy.com ;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root /opt/wwwroot/bbs.jedy.com; \\ 主目录
index index.html index.htm index.php;
}
\\ 去掉以下内容前的注释 支持php功能
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /opt/wwwroot/bbs.jedy.com$fastcgi_script_name;
include fastcgi_params;
}
[root@localhost ~]#

##################################脚本结束#####################################

[root@localhost ~]# chmod +x /etc/init.d/nginx
[root@localhost ~]# chkconfig --add nginx
[root@localhost ~]# chkconfig --level 345 nginx on
[root@localhost ~]# service nginx start
[root@localhost ~]# netstat -tlnp | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 25540/nginx
[root@localhost ~]#

4， 测试

[root@localhost ~]# vi /opt/wwwroot/bbs.jedy.com/test.php 内容如下
/<?
phpinfo()
?>
[root@localhost ~]#
在浏览器中输入 http://bbs.jedy.com \\ 如果出来了欢迎信息，说明nginx安装成功
在浏览器中输入 http://bbs.jedy.com/test.php \\ 如果出来了php的内容，说明成功php集成成功
[root@localhost ~]#
[root@localhost ~]#

 第四：MYSQL的安装和配置：

1， 安装 mysql mysql-server

[root@localhost ~]# yum install mysql mysql-server nginx php php-fpm php-cli php-pdo php-mysql php-mcrypt php-mbstring php-gd php-tidy php-xml php-xmlrpc php-pear php-pecl-memcache php-eaccelerator

2， 更改mysql默认的数据目录 为 /opt/data

1） 创建目录
[root@localhost ~]# mkdir /opt/data
2） 把MySQL服务进程停掉
[root@localhost ~]# service mysqld stop
3） 把/var/lib/mysql整个目录移到/home/data
[root@localhost ~]# mv /var/lib/mysql/* /opt/data/
这样就把MySQL的数据文档移动到了/home/data/下。
4） 找到my.cnf配置文档
假如/etc/目录下没有my.cnf配置文档，请到/usr/share/mysql/下找到*.cnf文档，拷贝其中一个到/etc/并改名为my.cnf)中。
命令如下：
[root@localhost ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
5） 编辑MySQL的配置文档/etc/my.cnf
为确保MySQL能够正常工作，需要指明mysql.sock文档的产生位置。修改socket=/var/lib/mysql/mysql.sock一行中等号右边的值为：/home/mysql/mysql.sock 。操作如下： .
[root@localhost ~]# vi my.cnf (用vi工具编辑my.cnf文档，找到下列数据修改之，有的版本上是有的，就不用改了) .
# The MySQL server
[mysqld]
port = 3306
#socket = /var/lib/mysql/mysql.sock(原内容，为了更稳妥用“#”注释此行)
socket = /opt/data/mysql/mysql.sock (加上此行) .
my.cnf 全文如下：

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
[client]
#password = your_password

#socket = /opt/data/mysql.sock

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.

# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
log-bin=mysql-bin
# binary logging format - mixed recommended
binlog_format=mixed
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 1
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
#
# binary logging - not required for slaves, but recommended

6） 修改MySQL启动脚本/etc/init.d/mysqld
