注意:源码编译完mysql后,就不要再安装mariadb-server,不然源码的脚本会被覆盖掉

 

 源码安装 mysql

 

使用cmake,make,make install命令,cmake的命令可以显示安装的进度的百分比

 

mysql 官网:www.mysql.com

 

软件包依赖性:

1 yum install -y gcc gcc-c++ make ncurses-devel cmake

 

2 tar  zxf mysql-boost-5.7.17.tar.gz

由于ncurses-devel已经装过,(可用rpm   -q   ncurses-devel查看),因此是CMakeCache.txt文件的影响,cmake在编译的过程中,会产生缓存文件,当继续编译时,就会从刚才停下的地方继续编译,而刚才停下的地方就是出错的地方,因此要将该缓存文件删除

 

[root@server1 mysql-5.7.17]# rm -f CMakeCache.txt

3 make&&makeinstall

 

 

 nginx和php联系在一起

 

1 cd php-5.6.20

 

2 cp php.ini-production /usr/local/lnmp/php/etc/php.ini###将配置文件移到/usr/local/lnmp/php/etc/下,并且一定以要命名为php.ini

 

 

3 cp    sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

 

4 chmod   +x/etc/init.d/php-fpm

 

5 vim /usr/local/lnmp/php/etc/php.ini

 

内容:

 

date.timezone=Asia/Shanghai

 

 

6 cp  /usr/local/lnmp/php/etc/php-fpm.conf.default  /usr/local/lnmp/php/etc/php-fgm.conf

 

7 vim  php-fpm.conf

 

内容:

pid = run/php-fgm.pid

 

8 /etc/init.d/php-fpm   reload###使用的fastcgi,有后台进程,有自己的端口(:9000),因此可以直接reload###

 

9 vim  ~/.bash_profile

 

内容:

PATH=$PATH:$HOME/bin:/usr/local/lnmp/mysql/bin:/usr/local/lnmp/php/bin

 

10 source  ~/.bash_profile

 


 

11 netstat-antlp    | grep  :9000

 

12 vim  /usr/local/lnmp/nginx/conf/nginx.conf

 

内容:

   location / {

            root   html;

            index  index.php index.html index.htm;

        }

 

 

 

 

 location ~ \.php$ {

            root           html;

            fastcgi_pass   127.0.0.1:9000;

            fastcgi_index  index.php;

            #fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

            include        fastcgi.conf;

 

13 vim   /usr/local/lnmp/nginx/html/index.php

 

内容:

 

<?php

phpinfo()

?>

 

 

测试:

 

访问172.25.78.1可以看到php的信息页

 

 

 

 nginx+php+mysql

 

 

client  -- >  nginx将所有的php的处理转发 --- >  php-fpm(端口号为9000) --- > php-mysqlnd --- > mysql:3306  --- > nginx  --- > client

 

部署论坛

 

1 网上下载一个论坛的压缩包并解压

unzip Discuz_X3.2_SC_UTF8.zip

 

2 less  readme/readme.txt###查看论坛部署的方法###

 

3 mv upload/ /usr/local/lnmp/nginx/html/bbs###readme.txt中写的要上传upload到服务器###

 

 

4 cd /usr/local/lnmp/nginx/html/bbs/

 

5 chmod 777 config/ uc_client/ data/ uc_server/ -R###安装过程要将目录权限开启###

 

 

安装过程会碰到该问题:

数据库连接错误:php不能连接到数据库

 

解决:

php的配置文件里指定数据库socket的位置

 

vim  /usr/local/lnmp/php/php.ini

 

内容:

**************************************************************

mysqli.default_socket = /usr/local/lnmp/mysql/data/mysql.sock

pdo_mysql.default_socket= /usr/local/lnmp/mysql/data/mysql.sock

mysql.default_socket = /usr/local/lnmp/mysql/data/mysql.sock

 

**************************************************************

 

 /etc/init.d/php-fpm  reload

 

 

还会碰到由于权限而无法连接数据库:

 

Permission denied

 

解决:

chmod 755 /usr/local/lnmp/mysql/data/

 

 

 

 

 

###php功能模块的扩展###

 

 

client  -- >  nginx将所有的php的处理转发 --- >  php-fpm(端口号为9000) --- > php-mysqlnd --- > mysql:3306  --- > nginx  --- > client

 

 

 

memcache

 

它是一个高性能的分布式的内存对象缓存系统,通过在内存里维护一个统一的巨大的 Hash 表,能够用来存储各种格式的数据。可以类比于 MySQL 这样的服务,而 PHP 扩展的 Memcache 实际上是连接Memcache 的方式,一般的使用目的是,通过缓存数据库查询结果,减少数据库访问次数,以提高动态web应用的速度,提高可扩展性。

 

可通过php   -m  |  grep   memcached   查看是否有memcached模块,php   -m显示所有的php编译的模块,如果没有就要通过phpize添加该功能模块。

phpize官方说明:是用来扩展php扩展模块的,通过phpize可以建立php的外挂模块。

 

******************************************************************************************

使用phpize扩展memcached模块的步骤:

 

1 下载网址 http://memcached.googlecode.com/

 

tar zxf memcache-2.2.5.tgz

 

2  cd memcache-2.2.5

 

3 phpize(我已经将路径加入到~/.bash_profile文件下,如果没有加入的要用绝对路径)

 

 

****************************************

可能出现的问题:

Cannot find config.m4.

解决:

是因为你没有cd到memcache-2.2.5目录下

***************************************

 

4 ./configure

 

5 make  &&  make insall

 

6 vim   /usr/local/lnmp/php/etc/php.ini

 

内容:(配置文件里有说明添加扩展模块怎么写,模仿着写)

 

extension=memcache.so

 

7 /etc/init.d/php-fpm reload

 

 

*******************************************************************************************

可能出现reload服务后仍然没有memcache的情况,这时要检查你使用的是系统带有的rpm包,还是源码编译的包,如果是系统的rpm包则要先把系统的包删除,然后就可以了

[root@server1 etc]# which php

/usr/bin/php

[root@server1 etc]# rpm -qa|grep php

php-cli-5.3.3-26.el6.x86_64

php-common-5.3.3-26.el6.x86_64

php-5.3.3-26.el6.x86_64

[root@server1 etc]# rpm -e `rpm -qa|grep php`

[root@server1 etc]# source  ~/.bash_profile

[root@server1 etc]# which php

/usr/local/lnmp/php/bin/php

[root@server1 etc]# php -m |grep mem

memcache

******************************************************************************************

 

 

###往mecache里存信息###

[root@server1 ~]# telnet localhost 11211

Trying ::1...

Connected to localhost.

Escape character is '^]'.

set name 0 0 6###第二个0指不过期,如果是10,则指10后过期,6指的是存的字符数为6####

westos

STORED

get name

VALUE name 0 6

westos

END

delete name

DELETED

get name

END

 

 

 

###openresty###

 

nginx本身具有高并发的特点,如果将缓存放在php后面,则客户请求发给nginx,nginx给php-fpm处理,然后缓存到memcache上,则nginx就要等待php-fpm的处理结束,那么就会影响到ngnix本身的效率,但是,如果把memcache放在nginx之后,客户请求过来,如果缓存里有,就可以直接从memcache中取来发给客户端,而不用再等php-fpm,因此就不会影响到nginx的效率,将缓存放在nginx之后需要memc和srcache模块,此实验直接安装openresty做更方便。

 

openresty是一个全功能的web服务器。他打包了标准的nginx核心,很多的常用的第三方模块,以及他们大多数的依赖项。(来自官网)

 

vim /usr/local/openresty/nginx/conf/nginx.conf

 

内容:

  upstream memcache {

                server  127.0.0.1:11211;

                keepalive 512;

        }

 

        location /memc {

                internal;

                 memc_connect_timeout 100ms;

                memc_send_timeout 100ms;

                memc_read_timeout 100ms;

                 set $memc_key $query_string;

                set $memc_exptime 300;

                memc_pass memcache;

 

        }

 

  location ~ \.php$ {

             set $key $uri$args;

             srcache_fetch GET /memc $key;

             srcache_store PUT /memc $key;

            root           html;

            fastcgi_pass   127.0.0.1:9000;

            fastcgi_index  index.php;

           # fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

            include        fastcgi.conf;

        }

 

 

 

 

 

 

 

具体过程如下:

[root@server1 ~]# tar zxf openresty-1.11.2.3.tar.gz

[root@server1 ~]# cd openresty-1.11.2.3

[root@server1 openresty-1.11.2.3]# ls

build   configure  Makefile  README.markdown   util

bundle  COPYRIGHT  patches   README-win32.txt

[root@server1 openresty-1.11.2.3]# cd /usr/local/openresty/

[root@server1 openresty]# nginx -s stop
