LAMP环境搭建

ooioiiuu

1. 安装mysql
###############################
注意，刚开始安装出错，原因是二进制包下载错了，本机centos是32位的，却下载了个64位的二进制包
###############################
[iyunv@chen src]# cd /usr/local/src/
[iyunv@chen src]# wget http://mirrors.sohu.com/mysql/MySQL-5.1/mysql-5.1.73-linux-x86_64-glibc23.tar.gz   
#二进制包免编译，若是64位系统，则下载这个包，32位则下载下面排错时的包
[iyunv@chen src]# tar zxvf mysql-5.1.73-linux-x86_64-glibc23.tar.gz
[iyunv@chen src]# mv mysql-5.1.73-linux-x86_64-glibc23 /usr/local/mysql
[iyunv@chen ~]# useradd -s /sbin/nologin mysql
[iyunv@chen ~]# cd /usr/local/mysql
[iyunv@chen mysql]# mkdir -p /data/mysql
[iyunv@chen mysql]# chown -R mysql:mysql /data/mysql
[iyunv@chen mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
./scripts/mysql_install_db: line 249: ./bin/my_print_defaults: cannot execute binary file
Neither host 'chen' nor 'localhost' could be looked up with
./bin/resolveip
Please configure the 'hostname' command to return a correct
hostname.
If you want to solve this at a later stage, restart this script
with the --force option
########################
此时出现错误,经过搜集资料，发现是因为本机系统为32位，却下载了一个64位的二进制包
使用命令如下命令查看本机系统是32位，还是64位
[iyunv@chen mysql]# getconf LONG_BIT
32

########################
#重新下下载一个对应包，再进行之前的操作，错误解决
[iyunv@chen mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
#出现两个OK则正确安装上了
[iyunv@chen mysql]# cp support-files/my-large.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y       #由于系统自带此文件，需要将它覆盖掉
[iyunv@chen mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[iyunv@chen mysql]# chmod 755 /etc/init.d/mysqld
[iyunv@chen mysql]# vim /etc/init.d/mysqld   #修改basedir和basedir,如下：

# overwritten by settings in the MySQL configuration files.

basedir=/usr/local/mysql
datadir=/data/mysql


[iyunv@chen mysql]# chkconfig --add mysqld
[iyunv@chen mysql]# chkconfig mysqld on
[iyunv@chen mysql]# service mysqld start
Starting MySQL............. SUCCESS!
#成功安装并启动mysql


2. 安装apache
[iyunv@chen src]# wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.2.31.tar.gz
[iyunv@chen src]# tar zxvf httpd-2.2.31.tar.gz
[iyunv@chen src]# cd httpd-2.2.31
[iyunv@chen httpd-2.2.31]# ./configure --prefix=/usr/local/apache2 --with-included-apr  --with-pcre --enable-mods-shared=most
[iyunv@chen httpd-2.2.31]# echo $?   #检查上一步是否出错，若为0则未出错，非0则有错
0
[iyunv@chen httpd-2.2.31]# make && make install
[iyunv@chen httpd-2.2.31]# echo $?
0

3.  安装php
[iyunv@chen src]# wget http://cn2.php.net/distributions/php-5.3.28.tar.gz
[iyunv@chen src]# tar zxf php-5.3.28.tar.gz
[iyunv@chen src]# cd php-5.3.28
[iyunv@chen php-5.3.28]# ./configure   --prefix=/usr/local/php   --with-apxs2=/usr/local/apache2/bin/apxs   --with-config-file-path=/usr/local/php/etc   --with-mysql=/usr/local/mysql   --with-libxml-dir   --with-gd   --with-jpeg-dir   --with-png-dir   --with-freetype-dir   --with-iconv-dir   --with-zlib-dir   --with-bz2   --with-openssl   --with-mcrypt   --enable-soap   --enable-gd-native-ttf   --enable-mbstring   --enable-sockets   --enable-exif   --disable-ipv6
######################
执行上面命令的过程中会遇到一些依赖缺少的提示，下面列出我遇到的依赖问题：错误：configure: error: xml2-config not found. Please check your libxml2 installation.解决：yum  install -y  libxml2-devel错误：configure: error: jpeglib.h not found.解决：yum  install -y  libjpeg-devel错误：configure: error: mcrypt.h not found. Please reinstall libmcrypt.解决：yum  install  -y  libmcrypt-devel由于版权原因，可能无法直接安装上面的包，在百度经验里找到了一个解决办法：http://jingyan.baidu.com/article/54b6b9c0e94f1e2d583b4782.html错误：checking for recode support... yesconfigure: error: Can not find recode.h anywhere under /usr /usr/local /usr /opt.解决：yum  install -y  librecode-devel
######################

重新编译执行如上操作，出现以下提示，则表明安装成功：

Thank you for using PHP.

[iyunv@chen php-5.3.28]# echo $?
0
[iyunv@chen php-5.3.28]# make && make install

[iyunv@chen php-5.3.28]# echo $?

0

[iyunv@chen php-5.3.28]#  cp php.ini-production /usr/local/php/etc/php.ini     #拷贝配置文件

4. 配置apache结合php
vim /usr/local/apache2/conf/httpd.conf找到：

    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all

改为：

    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Allow from all




找到:
AddType application/x-gzip .gz .tgz
在该行下面添加:

AddType application/x-httpd-php .php
找到:

    DirectoryIndex index.html

将该行改为:

    DirectoryIndex index.html index.htm index.php

找到:
#ServerName www.example.com:80
修改为:
ServerName localhost:80

查看配置文件是否有问题：
/usr/local/apache2/bin/apachectl -t
如果显示Syntax OK，则没有问题了。然后启动服务：
/usr/local/apache2/bin/apachectl start
检查Apache是否正常启动：
[iyunv@chen php-5.3.28]# ps aux |grep httpd
root      6733  0.0  1.0  28912  9952 ?        Ss   03:58   0:00 /usr/local/apache2/bin/httpd -k start
daemon    6734  0.0  0.9  28912  8716 ?        S    03:58   0:00 /usr/local/apache2/bin/httpd -k start
daemon    6735  0.0  0.9  28912  8716 ?        S    03:58   0:00 /usr/local/apache2/bin/httpd -k start

daemon    6738  0.0  0.9  28912  8716 ?        S    03:58   0:00 /usr/local/apache2/bin/httpd -k start
root      6753  0.0  0.0   6052   788 pts/0    S+   04:01   0:00 grep httpd
5. 测试解析php
vim /usr/local/apache2/htdocs/1.php
写入:

<?php
    echo "php解析正常";
?>
保存后，继续测试:

curl localhost/1.php
