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

<VirtualHost *:80>

    ServerAdmin webmaster@dummy-host.example.com

    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>

<VirtualHost *:80>

    ServerAdmin webmaster@dummy-host2.example.com

        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>

<VirtualHost *:80>

        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

3)

    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

1. 在httpd.conf(Apache主配置文件)中增加：

AddType application/x-httpd-php .php    

1. 找到下面这段话:

<IfModule dir_module>

DirectoryIndex index.html

</IfModule>

在index.html 前面添加index.php

1. 建立php测试网页

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

输入如下内容:

<?php

phpinfo();

?>

1. 重启apache

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

1. 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!

1. 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;

2. 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

• ps –A | grep http
• 杀死apache对应进程

killall httpd 杀死全部的httpd进程

1. 把默认apache服务给删除

   

2. 启动自己的apache
