LAMP安装各种问题解决方案

LAMP环境配置安装注意安装步骤及说明事项。

LAMP安装各种问题解决

1. 访问ftp报错

解决：

关闭selinux

vi /etc/selinux/config

内容修改为： selinux=disable

之后重启reboot。

下图分别为selinux关闭前和关闭后：

2. 依赖软件查询

http://rpmfind.net

一．安装gcc

gcc

cloog-ppl

ppl(libppl.so.7/libppl_c.so.2)

cpp

mpfr(libmpfr.so.1)

gcc-c++

libstdc++-devel

mpfr-2.4.1-6.el6.i686.rpm和ppl-0.10.2-11.el6.i686.rpm

快捷键rz sz：

rz、sz命令没找到？

安装lrzsz即可：

shell># yum -y install lrzsz

二．安装zlib压缩库

shell>## cd /home/jinnan/tar

shell># tar –zxvf zlib-1.2.5.tar.gz

shell># cd zlib-1.2.5

shell># ./configure //这个配置编译命令不要加目录参数

shell># make && make install

三．安装apache

shell># cd /home/jinnan/tar

shell># tar -jxvf httpd-2.2.19.tar.bz2

shell># cd httpd-2.2.19

shell>#./configure --prefix=/usr/local/http2 \

--enable-modules=all \

--enable-mods-shared=all \

--enable-so

shell># make && make install

启动Apache

shell># /usr/local/http2/bin/apachectl start

#测试apache

浏览器打开: http://虚拟机IP

看到 "it works!",即为成功

配置虚拟主机

1）配置host文件

打开C:/windows/system32/drivers/etc/hosts 文件

增加域名记录

如：

192.168.9.38 www.ec1.com

192.168.9.38 www.ec2.com

2) 增加虚拟主机

vi /usr/local/http2/conf/httpd.conf

取消# Include conf/extra/httpd-vhosts.conf

这一行前面的#号

保存退出

vi /usr/local/http2/conf/extra/httpd-vhosts.conf

增加虚拟主机记录

ServerAdmin [email protected]

DocumentRoot "/usr/local/http2/htdocs/ec1"

ServerName www.ec1.com

ServerAlias www.dummy-host.example.com

ErrorLog "logs/dummy-host.example.com-error_log"

CustomLog "logs/dummy-host.example.com-access_log" common

</VirtualHost>

ServerAdmin [email protected]

DocumentRoot "/usr/local/http2/htdocs/ec2"

ServerName www.ec2.com

ErrorLog "logs/dummy-host2.example.com-error_log"

CustomLog "logs/dummy-host2.example.com-access_log" common

</VirtualHost>

DocumentRoot "/var/www/shop"

ServerName www.ec1.com

</VirtualHost>

注意：/var/www/shop 以上三个目录var www shop 的其他用户必须有x可执行权限

shell># cd /usr/local/http2/htdocs

shell># mkdir ec1 ec2

shell># echo this is ec1.com > ec1/index.html

shell># echo this is ec2.com > ec2/index.html

4）重启apache

/usr/local/http2/bin/apachectl restart

5)浏览器打开www.ec1.com,和www.ec2.com

看到不同的网站内容，虚拟主机创建完毕！

安装图形库,为编译PHP做准备

libxml2-2.7.2.tar.gz

jpegsrc.v8b.tar.gz

libpng-1.4.3.tar.gz

freetype-2.4.1.tar.gz

gd-2.0.35.tar.gz

四．安装libxml2

shell># cd /home/jinnan/tar

shell># tar zxvf libxml2-2.7.2.tar.gz

shell># cd libxml2-2.7.2

shell>#./configure --prefix=/usr/local/libxml2 \

--without-zlib

shell># make && make install

五．安装jpeg8

shell># cd /home/jinnan/tar

shell># tar -zxvf jpegsrc.v8b.tar.gz

shell># cd jpeg-8b

shell>#./configure --prefix=/usr/local/jpeg \

--enable-shared --enable-static

shell># make && make install

--enable-shared 把jpeg需要的函数库程序都编译到该软件里边

优点：函数调用速度快

缺点：软件本身比较大

--enable-static 静态方式函数处理，需要什么函数，马上include来

优点：软件本身比较小

缺点：函数调用速度慢

六．安装libpng

shell># cd /home/jinnan/tar

shell># tar zxvf libpng-1.4.3.tar.gz

shell># cd libpng-1.4.3

shell>#./configure #和zlib一样不要带参数，让它默认安装到相应目录

shell># make && make install

七．安装freetype(字体库)

shell># cd /home/jinnan/tar

shell># tar zxvf freetype-2.4.1.tar.gz

shell># cd freetype-2.4.1

shell>#./configure --prefix=/usr/local/freetype

shell># make && make install

八．安装GD库

shell># cd /home/jinnan/tar

shell># tar -zvxf gd-2.0.35.tar.gz

shell># mkdir -p /usr/local/gd

shell># cd gd-2.0.35

shell>#./configure --prefix=/usr/local/gd \

--with-jpeg=/usr/local/jpeg/ \

--with-png --with-zlib \

--with-freetype=/usr/local/freetype

shell># make && make install

九．安装 php5

shell># cd /home/jinnan/tar

shell># tar -jxvf php-5.3.6.tar.bz2

shell># cd php-5.3.6

shell>#./configure --prefix=/usr/local/php \

--with-apxs2=/usr/local/http2/bin/apxs \

--with-mysql=mysqlnd \

--with-pdo-mysql=mysqlnd \

--with-mysqli=mysqlnd \

--with-freetype-dir=/usr/local/freetype \

--with-gd=/usr/local/gd \

--with-zlib --with-libxml-dir=/usr/local/libxml2 \

--with-jpeg-dir=/usr/local/jpeg \

--with-png-dir \

--enable-mbstring=all \

--enable-mbregex \

--enable-shared

shell># make && make install

复制php.ini配置文件到指定目录

shell># cp php.ini-development /usr/local/php/lib/php.ini

配置Apache使其支持php

vi /usr/local/http2/conf/httpd.conf

在httpd.conf(Apache主配置文件)中增加：

AddType application/x-httpd-php .php

找到下面这段话:

DirectoryIndex index.html

</IfModule>

在index.html 前面添加index.php

建立php测试网页

vi /usr/local/apache2/htdocs/index.php

输入如下内容:

<?php

phpinfo();

重启apache

shell># /usr/local/http2/bin/apachectl restart

再次浏览器查看http://虚拟机IP

如果看到php信息,工作就完成了!

安装MySQL

1.安装cmake

shell># cd /home/jinnan/tar

shell># tar zxvf cmake-2.8.5.tar.gz

shell># cd cmake-2.8.5

shell># ./bootstrap

shell># make && make install

2.编译安装MySQL

shell># cd /home/jinnan/tar

shell># tar zxvf mysql-5.5.17.tar.gz

shell># cd mysql-5.5.17

shell># cmake \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/usr/local/mysql/data \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci

(准备安装到那里

数据存储目录

默认的字符集

校对字符集)

(报错就安装ncurses-devel)

shell># mount .....挂载光盘/

shell># rpm -ivh ncurses-devel-5.7-3.20090208.el6.i686.rpm

shell># rm -f CMakeCache.txt //删除该文件

shell># cmake 。。。。。。//重新cmake

shell># make && make install

shell># cp support-files/my-medium.cnf /etc/my.cnf

3.配置并初始化MySQL

shell># useradd mysql (该mysql用户会存在于同名的组下)

shell># chmod +x /usr/local/mysql

(数据库用户信息不小心删除光了，删除data目录，从此开始执行以下指令,直至结束)

shell># chown -R mysql.mysql /usr/local/mysql

初始化mysql数据库

shell># /usr/local/mysql/scripts/mysql_install_db \

--user=mysql \

--basedir=/usr/local/mysql \

--datadir=/usr/local/mysql/data &

把mysql安装文件(除了data)的主人都改为root，避免数据库恢复为出厂设置。

shell># chown -R root /usr/local/mysql

shell># chown -R mysql /usr/local/mysql/data

& 后台运行mysql服务

shell># /usr/local/mysql/bin/mysqld_safe --user=mysql &

//查看mysql是否有启动

shell># ps –A | grep mysql

测试数据库

shell># /usr/local/mysql/bin/mysql –u root

mysql> show databases;

接上步,修改mysql密码(可不做此步,默认无密码)

mysql> UPDATE user SET Password=password('123456') WHERE user='root';

mysql> flush privileges;
配置开机自启动服务项

shell># cp 安装包解压目录/support-files/mysql.server /etc/init.d/mysqld

shell># chmod +x /etc/init.d/mysqld

shell># chkconfig --add mysqld

shell># chkconfig mysqld on //设置开机自启动

配置文件路径：

shell># vi /etc/rc.d/rc.local

在文件中增加启动相关服务的命令如下：

/usr/local/http2/bin/apachectl start

/usr/local/mysql/bin/mysqld_safe --user=mysql &

service vsftpd start

重新安装apache启动失败

[root@localhost httpd-2.2.19]# /usr/local/http2/bin/apachectl restart

httpd not running, trying to start

(98)Address already in use: make_sock: could not bind to address [::]:80

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

Unable to open logs

原因是80端口被占用

解决：

查看80端口使用情况

[root@localhost httpd-2.2.19]# netstat -lnp|grep 80

tcp 0 0 :::80 :::* LISTEN 28195/httpd

unix 2 [ ACC ] STREAM LISTENING 6580 1957/gpm /dev/gpmctl

unix 2 [ ACC ] STREAM LISTENING 5422 1800/pcscd /var/run/pcscd.comm

查看80的使用者是谁端口

[root@localhost httpd-2.2.19]# ps 28195

PID TTY STAT TIME COMMAND

28195 ? Ss 0:00 /usr/local/http2/bin/httpd -k restart

经过分析知道了80端口被系统的一个进程占用，这个进程是旧的apache服务

将这个进程杀之

[root@localhost httpd-2.2.19]# kill -9 28195

[root@localhost httpd-2.2.19]#

十一．卸载操作系统自带apache
1. 删除默认apache进程
