PHP网站制作之php+mysql+nginx在linux上的情况部署

也或许是因为我还没有真正的学到深处吧，说实在的，PHP中的很多高级点的应用，如PHP类、PHP函数基本还是不懂吧！一向在linux上鼓捣，还没有完全在linux下设置过nginx服务器情况部署呢，这几天没甚么事就部署了一下，碰到的成绩也良多，如今把我的情况部署文档收回了，有甚么成绩人人能够一同会商一下，但愿人人接纳后碰到成绩多多相同。

1、编译安装PHP5.2.14所需的撑持库：
tarzxvflibiconv-1.13.1.tar.gz
cdlibiconv-1.13.1/
./configure--prefix=/usr/local
make
makeinstall

tarzxvfmcrypt-2.6.8.tar.gz
cdmcrypt-2.6.8/
/sbin/ldconfig
./configure
make
makeinstall
cd../

关于/etc/ld.so.conf:
这个文件纪录了编译时利用的静态链接库的路径。
默许情形下，编译器只会利用/lib和/usr/lib这两个目次下的库文件
将本人大概寄存库文件的路径都到场到/etc/ld.so.conf中是明智的选择
增加办法也极为复杂，将库文件的相对路径间接写出来就OK了，一行一个。比方：
/usr/X11R6/lib
/usr/local/lib
/opt/lib

ldconfig是甚么?
它是一个程序，一般它位于/sbin下，供root用户利用。它的感化就是将/etc/ld.so.conf列出的路径下的库文件缓存到/etc/ld.so.cache以供利用，因而当安装完一些库文件，大概修正ld.so.conf增添新的库路径后，必要运转一下/sbin/ldconfig，使一切的库文件都被缓存到ld.so.cache中，假如没做，即便库文件明显就在/usr/lib下的，也是不会被利用的，了局编译过程当中报错，短少xxx库。牢记修改库文件后必定要运转一下ldconfig，在任何目次下运转都能够。
2、编译安装MySQL5.5.3-m3
/usr/sbin/groupaddmysql
/usr/sbin/useradd-gmysqlmysql
tarzxvfmysql-5.5.3-m3.tar.gz
cdmysql-5.5.3-m3/
./configure--prefix=/home/pubsrc/mysql/--enable-assembler--with-extra-charsets=complex--enable-thread-safe-client--with-big-tables--with-readline--with-ssl--with-embedded-server--enable-local-infile--with-plugins=partition,innobase,myisammrg
make&&makeinstall
chmod&#43;w/home/pubsrc/mysql
chown-Rmysql:mysql/home/pubsrc/mysql/
cd../
　　①、创立MySQL数据库寄存目次
mkdir-p/home/pubsrc/mysql/data/
mkdir-p/home/pubsrc/mysql/logs/binlog/
mkdir-p/home/pubsrc/mysql/logs/relaylog/
chown-Rmysql:mysql/home/pubsrc/mysql/
②、以mysql用户帐号的身份创建数据表：
/home/pubsrc/mysql/bin/mysql_install_db--basedir=/home/pubsrc/mysql--datadir=/home/pubsrc/mysql/data--user=mysql
③、创立my.cnf设置文件：
vi/home/pubsrc/mysql/my.cnf
输出以下内容：
[client]
#character-set-server=utf8
port=3306
socket=/tmp/mysql.sock

[mysqld]
#character-set-server=utf8

max_allowed_packet=32M


④、创立办理MySQL数据库的shell剧本：
vi/home/pubsrc/mysql/mysql
#!/bin/sh
mysql_port=3306
mysql_username="admin"
mysql_password="12345678"

function_start_mysql()
{
printf"StartingMySQL...
"
/bin/sh/home/pubsrc/mysql/bin/mysqld_safe--defaults-file=/home/pubsrc/mysql/my.cnf2>&1>/dev/null&
}

function_stop_mysql()
{
printf"StopingMySQL...
"
/home/pubsrc/mysql/bin/mysqladmin-u${mysql_username}-p${mysql_password}-S/tmp/mysql.sockshutdown
}

function_restart_mysql()
{
printf"RestartingMySQL...
"
function_stop_mysql
sleep5
function_start_mysql
}

function_kill_mysql()
{
kill-9$(ps-efgrepbin/mysqld_safegrep${mysql_port}awk{printf$2})
kill-9$(ps-efgreplibexec/mysqldgrep${mysql_port}awk{printf$2})
}

if["$1"="start"];then
function_start_mysql
elif["$1"="stop"];then
function_stop_mysql
elif["$1"="restart"];then
function_restart_mysql
elif["$1"="kill"];then
function_kill_mysql
else
printf"Usage:/data0/mysql/${mysql_port}/mysql{startstoprestartkill}
"
fi
⑤、付与shell剧本可实行权限：
chmod&#43;x/home/pubsrc/mysql/mysql
⑥、启动MySQL：
/home/pubsrc/mysql/mysqlstart
⑦、经由过程命令行登录办理MySQL服务器（提醒输出暗码时间接回车）：
/home/pubsrc/mysql/bin/mysql-uadmin-p-S/tmp/mysql.sock
⑧、输出以下SQL语句，创立一个具有root权限的用户（admin）和暗码（12345678）：
GRANTALLPRIVILEGESON*.*TOadmin@localhostIDENTIFIEDBY12345678;
GRANTALLPRIVILEGESON*.*TOadmin@127.0.0.1IDENTIFIEDBY12345678;
⑨、（可选）中断MySQL：
/home/pubsrc/mysql/mysqlstop
3、编译安装PHP（FastCGI形式）
tarzxvfphp-5.2.14.tar.gz
gzip-cdphp-5.2.14-fpm-0.5.14.diff.gzpatch-dphp-5.2.14-p1
cdphp-5.2.14/




./configure--prefix=/home/pubsrc/php--with-config-file-path=/home/pubsrc/php/etc--with-mysql=/home/pubsrc/mysql--with-mysqli=//home/pubsrc/mysql/bin/mysql_config--with-iconv-dir=/usr/local--with-freetype-dir--with-jpeg-dir--with-png-dir--with-zlib--with-libxml-dir=/usr--enable-xml--disable-rpath--enable-discard-path--enable-safe-mode--enable-bcmath--enable-shmop--enable-sysvsem--enable-inline-optimization--with-curl--with-curlwrappers--enable-mbregex--enable-fastcgi--enable-fpm--enable-force-cgi-redirect--enable-mbstring--with-mcrypt--with-gd--enable-gd-native-ttf--with-openssl--with-mhash--enable-pcntl--enable-sockets--with-ldap--with-ldap-sasl--with-xmlrpc--enable-zip--enable-soap--without-pear


makeZEND_EXTRA_LIBS=-liconv
makeinstall
cpphp.ini-dist/home/pubsrc/php/etc/php.ini
cd../
4、编译安装PHP5扩大模块
tarzxvfmemcache-2.2.5.tgz
cdmemcache-2.2.5/
/home/pubsrc/php/bin/phpize
./configure--with-php-config=/home/pubsrc/php/bin/php-config
make
makeinstall
cd../

tarjxvfeaccelerator-0.9.6.1.tar.bz2
cdeaccelerator-0.9.6.1/
/home/pubsrc/php/bin/phpize
./configure--enable-eaccelerator=shared--with-php-config=/home/pubsrc/php/bin/php-config
make
makeinstall
cd../

tarzxvfPDO_MYSQL-1.0.2.tgz
cdPDO_MYSQL-1.0.2/
/home/pubsrc/php/bin/phpize
./configure--with-php-config=/home/pubsrc/php/bin/php-config--with-pdo-mysql=/home/pubsrc/mysql
make
makeinstall
cd../

tarzxvfImageMagick.tar.gz
cdImageMagick-6.5.1-2/
./configure
make
makeinstall
cd../

tarzxvfimagick-2.3.0.tgz
cdimagick-2.3.0/
/home/pubsrc/php/bin/phpize
./configure--with-php-config=/home/pubsrc/php/bin/php-config
make
makeinstall
cd../
5、修正php.ini文件
　　手工修正：查找/home/pubsrc/php/etc/php.ini中的extension_dir="./"
　　修正为extension_dir="/home/pubsrc/php/lib/php/extensions/no-debug-non-zts-20060613/"
　　并在此行后增添以下几行，然后保留：
　　extension="memcache.so"
　　extension="pdo_mysql.so"
　　extension="imagick.so"

　　再查找output_buffering=Off
　　修正为output_buffering=On

　　再查找;cgi.fix_pathinfo=0
　　修正为cgi.fix_pathinfo=0，避免Nginx文件范例毛病剖析毛病。

　　主动修正：若嫌手工修正贫苦，可实行以下shell命令，主动完成对php.ini文件的修正：
sed-is#extension_dir="./"#extension_dir="/home/pubsrc/php/lib/php/extensions/no-debug-non-zts-20060613/"
extension="memcache.so"
extension="pdo_mysql.so"
extension="imagick.so"
#/home/pubsrc/php/etc/php.ini
sed-is#output_buffering=Off#output_buffering=On#/home/pubsrc/php/etc/php.ini
sed-i"s#;always_populate_raw_post_data=On#always_populate_raw_post_data=On#g"/home/pubsrc/php/etc/php.ini
sed-i"s#;cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g"/home/pubsrc/php/etc/php.ini
6、设置eAccelerator减速PHP：
mkdir-p/home/pubsrc/eaccelerator_cache
vi/home/pubsrc/php/etc/php.ini
按shift&#43;g键跳到设置文件的最开端，加上以下设置信息：
[eaccelerator]
zend_extension="/home/pubsrc/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/home/pubsrc/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
7、创立www用户和组，和供blog.test.com和www.test.com两个假造主机利用的目次：
/usr/sbin/groupaddwww
/usr/sbin/useradd-gwwwwww
mkdir-p/data0/htdocs/blog
chmod&#43;w/data0/htdocs/blog
chown-Rwww:www/data0/htdocs/blog
mkdir-p/data0/htdocs/www
chmod&#43;w/data0/htdocs/www
chown-Rwww:www/data0/htdocs/www
　8、创立php-fpm设置文件（php-fpm是为PHP打的一个FastCGI办理补钉，能够光滑变动php.ini设置而无需重启php-cgi）：
　　在/home/pubsrc/php/etc/目次中创立php-fpm.conf文件：
rm-f/home/pubsrc/php/etc/php-fpm.conf
vi/home/pubsrc/php/etc/php-fpm.conf
输出以下内容（假如您安装Nginx&#43;PHP用于程序调试，请将以下的0改成1，以便显现PHP毛病信息，不然，Nginx会报形态为500的空缺毛病页）：

9、启动php-cgi历程，监听127.0.0.1的9000端口，历程数为128（假如服务器内存小于3GB，能够只开启64个历程），用户为www：
ulimit-SHn65535
/home/pubsrc/php/sbin/php-fpmstart
注：/home/pubsrc/php/sbin/php-fpm另有其他参数，包含：startstopquitrestartreloadlogrotate，修正php.ini后不重启php-cgi，从头加载设置文件利用reload。
3、安装Nginx0.8.46
　　1、安装Nginx所需的pcre库：
tarzxvfpcre-8.10.tar.gz
cdpcre-8.10/
./configure
make&&makeinstall
cd../
2、安装Nginx
tarzxvfnginx-0.8.46.tar.gz
cdnginx-0.8.46/
./configure--user=www--group=www--prefix=/home/pubsrc/nginx--with-http_stub_status_module--with-http_ssl_module
make&&makeinstall
cd../
3、创立Nginx日记目次
mkdir-p/data1/logs
chmod&#43;w/data1/logs
chown-Rwww:www/data1/logs
4、创立Nginx设置文件
　　①、在/home/pubsrc/nginx/conf/目次中创立nginx.conf文件：
rm-f/home/pubsrc/nginx/conf/nginx.conf
vi/home/pubsrc/nginx/conf/nginx.conf
输出以下内容：
userwwwwww;

worker_processes8;

}
}
②、在/home/pubsrc/nginx/conf/目次中创立fcgi.conf文件：
vi/home/pubsrc/nginx/conf/fcgi.conf
输出以下内容：
fastcgi_paramGATEWAY_INTERFACECGI/1.1;
fastcgi_paramSERVER_SOFTWAREnginx;

#PHPonly,requiredifPHPwasbuiltwith--enable-force-cgi-redirect
fastcgi_paramREDIRECT_STATUS200;
5、启动Nginx
ulimit-SHn65535
/home/pubsrc/nginx/sbin/nginx
4、设置开机主动启动Nginx&#43;PHP
vi/etc/rc.local
在开端增添以下内容：
ulimit-SHn65535
/home/pubsrc/php/sbin/php-fpmstart
/home/pubsrc/nginx/sbin/nginx
5、优化Linux内核参数
vi/etc/sysctl.conf
在开端增添以下内容：
#Add
net.ipv4.tcp_max_syn_backlog=65536
net.core.netdev_max_backlog=32768
net.core.somaxconn=32768

net.core.wmem_default=8388608
net.core.rmem_default=8388608
net.core.rmem_max=16777216
net.core.wmem_max=16777216

net.ipv4.tcp_timestamps=0
net.ipv4.tcp_synack_retries=2
net.ipv4.tcp_syn_retries=2

net.ipv4.tcp_tw_recycle=1
#net.ipv4.tcp_tw_len=1
net.ipv4.tcp_tw_reuse=1

net.ipv4.tcp_mem=94500000915000000927000000
net.ipv4.tcp_max_orphans=3276800

#net.ipv4.tcp_fin_timeout=30
#net.ipv4.tcp_keepalive_time=120
net.ipv4.ip_local_port_range=102465535
使设置当即失效：
/sbin/sysctl-p
6、在一直止Nginx服务的情形下光滑变动Nginx设置
　　1、修正/home/pubsrc/nginx/conf/nginx.conf设置文件后，请实行以下命令反省设置文件是不是准确：
/home/pubsrc/nginx/sbin/nginx-t
假如屏幕显现以下两行信息，申明设置文件准确：
　　theconfigurationfile/home/pubsrc/nginx/conf/nginx.confsyntaxisok
　　theconfigurationfile/home/pubsrc/nginx/conf/nginx.confwastestedsuccessfully

　　2、光滑重启：
　　①、关于Nginx0.8.x版本，如今光滑重启Nginx设置十分复杂，实行以下命令便可：
/home/pubsrc/nginx/sbin/nginx-sreload
②、关于Nginx0.8.x之前的版本，光滑重启略微贫苦一些，依照以下步骤举行便可。输出以下命令检察Nginx主历程号：
ps-efgrep"nginx:masterprocess"grep-v"grep"awk-F{print$2}
　屏幕显现的即为Nginx主历程号，比方：
　　6302
　　这时候，实行以下命令便可使修正过的Nginx设置文件失效：
kill-HUP6302
大概无需这么贫苦，找到Nginx的Pid文件：
kill-HUP`cat/home/pubsrc/nginx/nginx.pid`
7、编写天天准时切割Nginx日记的剧本
　　1、创立剧本/home/pubsrc/nginx/sbin/cut_nginx_log.sh
vi/home/pubsrc/nginx/sbin/cut_nginx_log.sh
　输出以下内容：
#!/bin/bash
#Thisscriptrunat00:00

#TheNginxlogspath
logs_path="/home/pubsrc/nginx/logs/"

mkdir-p${logs_path}$(date-d"yesterday"&#43;"%Y")/$(date-d"yesterday"&#43;"%m")/
mv${logs_path}access.log${logs_path}$(date-d"yesterday"&#43;"%Y")/$(date-d"yesterday"&#43;"%m")/access_$(date-d"yesterday"&#43;"%Y%m%d").log
kill-USR1`cat/home/pubsrc/nginx/nginx.pid`
2、设置crontab，天天清晨00:00切割nginx会见日记
crontabCe
输出以下内容：
0000***/bin/bash/home/pubsrc/nginx/sbin/cut_nginx_log.sh

开启php.ini中的cgi.fix_pathinfo=0，避免Nginx文件范例毛病剖析毛病。
3,创立nginx启东剧本
vinginxctl
输出一下内容
#!/bin/bash

BIN=/home/pubsrc/nginx/sbin/nginx
PID=/home/pubsrc/nginx/nginx.pid
case$1in
start)
$BIN-c/home/pubsrc/nginx/conf/nginx.conf;
exit$?;
;;
stop)
kill$(cat$PID);
exit$?;
;;
reload)
kill-HUP$(cat$PID);
exit$?;
;;
rotate)
kill-USR1$(cat$PID);
exit$?;
;;
port)
echo"Yourportis$((4000&#43;$(id-u)))";
;;
*)
echo"Usage:$0{startstopreloadroateport}";
exit1;
esac
最初付与可实行权限
chmod777nginxctl



CentOS体系上CentOSMemcached安装。
1.CentOSMemcached安装前必要先安装Libevent:
#curl-Ohttp://www.monkey.org/~provos/libevent-1.4.9-stable.tar.gz
#tarzxflibevent-1.4.9-stable.tar.gz
#cdlibevent-1.4.9-stable
#./configure
#make
#makeinstall
2.持续CentOSMemcached安装:
#curl-Ohttp://www.danga.com/memcached/dist/memcached-1.2.7.tar.gz
#tarzxfmemcached-1.2.7.tar.gz
#cdmemcached-1.2.7
#./configure
#make
#makeinstall
3.CentOSMemcached安装接着在以后用户的.bash_profile中增加
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
exportLD_LIBRARY_PATH
4.CentOSMemcached运转
#memcached-m512-unobody-vv
测试时分发明会呈现以下毛病信息：
“/usr/local/memcached/bin/memcached:errorwhileloadingsharedlibraries:libevent-1.4.so.2:cannotopensharedobjectfile:Nosuchfileordirectory”
毛病的缘故原由是未在体系中注册Libevent.办理办法以下:
#vi/etc/ld.so.conf.d/libevent-i386.conf
在VI中输出以下一行内容：
/usr/local/lib/
最初不要忘了
#ldconfig
5.CentOSMemcached运转
#memcached-m512-unobody-vv

没接触过框架的人，也不用害怕，其实框架就是一种命名规范及插件，学会一个框架其余的框架都很好上手的。

曾经犯过一个很低级的错误，我在文件命名的时候用了一个横线\\\\\\\'-\\\\\\\' 号，结果找了好几个小时的错误，事实是命名的时候 是不能用横线 \\\\\\\'-\\\\\\\' 的，应该用的是下划线  \\\\\\\'_\\\\\\\' ;

要进行开发，搭建环境是首先需要做的事，windows下面我习惯把环境那个安装在C盘下面，因为我配的环境经常出现诡异事件，什么事都没做环境有的时候就不能用啦。

说点我烦的低级错误吧，曾经有次插入mysql的时间 弄了300年结果老报错，其实mysql的时间是有限制的，大概是到203X年  具体的记不清啦，囧。

建数据库表的时候，int型要输入长度的，其实是个摆设的输入几位都没影响的，只要大于4就行，囧。

首先我是坚决反对新手上来就用框架的，因为对底层的东西一点都不了解，造成知识上的真空，会对以后的发展不利。我的观点上手了解下框架就好，代码还是手写。当然啦如果是位别的编程语言的高手的话，这个就另当别论啦。
