LNMP企业应用部署全过程(基于DEDE后台)

 系统环境说明:

os:centos 5.6
nginx:nginx-1.0.11
php:php-5.3.9
mysql:mysql-5.5.20

文档导读:
一 准备工作
二 基础软件包安装
三 安装Nginx
四 MySQL安装
五 安装PHP
六 企业网站部署
七 压力测试webbench
八 优化mysql,nginx,php配置及防火墙配置(略)
九 维护常用命令

一、准备工作(仅作参考)
1、删除系统自带软件
rpm -qa httpd mysql php nginx
先停止服务,卸载软件命令:rpm -e httpd --nodeps

2、yum源
vim /etc/yum.repos.d/CentOS-Base.repo
服务器需要yum的时候也不多,所以并不需要去设置。
国内镜像:http://mirrors.163.com   http://mirrors.sohu.com

3、设置CentOS默认语言
cp /etc/sysconfig/i18n /etc/sysconfig/i18n_bak
vi /etc/sysconfig/i18n 
LANG="en_US.UTF-8" 
SYSFONT="latarcyrheb-sun16"
默认的语言是英文,如果把第一行改为"LANG=”zh_CN.UTF-8”",则本机上的shell可以看到正常的中文,但通过ssh连上就会发现所有的汉字变成乱码了;则再改为"LANG="zh_CN.GB18030"",重新登陆即可发现一切OK。

4、安装vim
Centos里的VI只默认安装了vim-minimal-7.x。所以无论是输入vi或者 vim查看文件,syntax功能都无法正常启用。因此需要用yum安装另外两个组件:vim-common-7.x和vim-enhanced- 7.x
yum -y install vim*

查看最近yum安装过的软件包
more /var/log/yum.log

5、时间同步
#当前时区调整为上海就是+8区
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
#利用ntpdate同步标准时间
ntpdate us.pool.ntp.org
注意:需要安装ntp-4.2.2p1-9.el5.centos.2.1.i386.rpm
或yum install -y ntp
加入定时计划任务,每隔10分钟同步一下时钟
crontab -e
0 23 * * * /bin/bash /usr/sbin/ntpdate us.pool.ntp.org | logger -t NTP

(升级系统软件包,服务和用户安全设置在此不涉及)

二 基础软件包安装
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

yum -y install make crontabs wget

其中wget看你使用情况,可以不装,openssl-devel对于不需要ssl安全连接的也可以不装,libtool一般在安装到nginx\php\mysql前会安装上去,所以这里也不用安装。make是编译所用,cmake是编译MySQL时用到,ncurses-devel也是。autoconf是编译eaccelerator时用到,crontabs为计划任务,日志分割所用。

附带介绍:
#检查是否安装gcc
gcc -v
#查询SELinux开启情况
getenforce

三、安装Nginx
1.创建nginx所需用户及目录
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www

mkdir -p /data0/htdocs/html
chmod +w /data0/htdocs/html
chown -R www:www /data0/htdocs/html
mkdir -p /data0/htdocs/web
chmod +w /data0/htdocs/web
chown -R www:www /data0/htdocs/web

mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs

2.安装nginx所需pcre
tar zxvf pcre-8.21.tar.gz && cd pcre-8.21/
./configure
make
make install
cd ../

3.开始安装nginx
tar zxvf nginx-1.0.11.tar.gz && cd nginx-1.0.11/
./configure --user=www --group=www \
--prefix=/usr/local/webserver/nginx \
--with-http_stub_status_module \
--with-http_ssl_module

make
make install
cd ../

4.配置nginx
cd /usr/local/webserver/nginx/conf/
mv nginx.conf nginx.conf_bak
vim nginx.conf
输入以下内容:
user  www www;
worker_processes 8;

error_log  /data1/logs/nginx_error.log  crit;
pid        /usr/local/webserver/nginx/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process. 
worker_rlimit_nofile 65535;

events 
{
  use epoll;
  worker_connections 65535;
}

http 
{
  include       mime.types;
  default_type  application/octet-stream;
  #charset  gb2312;
      
  server_names_hash_bucket_size 128;

  gzip on;
  gzip_min_length  1k;
  gzip_buffers     4 16k;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_types       text/plain application/x-javascript text/css application/xml;
  gzip_vary on;

  #limit_zone  crawler  $binary_remote_addr  10m;
 
  server
  {
    listen       80 default;
    server_name  _;
   # index index.html index.htm index.php;
    return 404;
  }
  
  server
  {
    listen       888;
    server_name  _;
   # index index.html index.htm index.php;
    return 404;
  }

  include vhost/*.conf;
  include vhost/admin/*.conf;
  include vhost/html/*.conf;

}

5.前后台分离配置文件
cd /usr/local/webserver/nginx/conf
#前台配置文件
vim server.html.conf
输入以下内容:
index index.html index.htm index.php;
location ~ /\.ht {
    deny all;
}
location ~ .*\.(sqlite|sq3)$ {
    deny all;
}
location ~ .*\.(php|php5)?$ {
    deny all;
}
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
      expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
      expires      1h;
    }

#后台配置文件
vim  server.conf
输入以下内容:
index index.html index.htm index.php;
location ~ /\.ht {
    deny all;
}
location ~ .*\.(sqlite|sq3)$ {
    deny all;
}
    location ~ .*\.(php|php5)?$
    {
      fastcgi_pass  127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi.conf;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
      expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
      expires      1h;
    }

6.启动Nginx服务并检查
ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx
ps -ef |grep nginx

7.简单站点部署测试
mkdir -p /usr/local/webserver/nginx/conf/vhost/html
cd /usr/local/webserver/nginx/conf/vhost/html
vim onbing.com.conf
输入以下内容:
server
  {
    listen 80;
    server_name  www.onbing.com onbing.com;
    index index.html index.htm  ;
    root  /data0/htdocs/html/onbing.com;
    
    include server.html.conf;  

    log_format html_onbing '$remote_addr - $remote_user [$time_local] "$request"'
              '$status $body_bytes_sent "$http_referer" '
              '"$http_user_agent" $http_x_forwarded_for';
    access_log  /data1/logs/access_html_onbing.log  html_onbing;
  }

#网站文件存放目录
mkdir -p /data0/htdocs/html/onbing.com
vim /data0/htdocs/html/onbing.com/index.html
输入以下内容:
<html>
<head><title>onbing</title></head>
<body bgcolor="white">
<center><h1>welcome to nginx</h1></center>
</body>
</html>

chown -R www:www /data0/htdocs/html/onbing.com

#配置文件测试并重载
/usr/local/webserver/nginx/sbin/nginx -t
/usr/local/webserver/nginx/sbin/nginx -s reload

注意:
1).测试时关闭iptables
/etc/init.d/iptables stop
2).域名做hosts指向
192.168.1.24  onbing.com
192.168.1.24  www.onbing.com
3).测试命令
curl -I www.onbing.com

8.nginx日志分割
mkdir -p /data0/sh
cd /data0/sh
vim cut_nginx_log.sh
#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/usr/local/webserver/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`

#检查crond服务是否启动
service crond status

#编辑任务计划
crontab -e
输入以下内容:
0 0 * * * /bin/bash /data0/sh/cut_nginx_log.sh

四、MySQL安装
#检查并更新安装mysql所需要依赖的软件包
yum install -y automake autoconf libtool ncurses-devel libxslt groff pcre-devel

#安装cmake,后面安装mysql配置时需要使用
#CMAKE安装MySQL的配置参数说明:http://blog.sina.com.cn/s/blog_53b13d950100we05.html
tar zxvf cmake-2.8.7.tar.gz && cd cmake-2.8.7/
./configure
gmake && gmake install  && cd ../

#创建mysql用户和组
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql

说明:设置mysql用户密码:/usr/bin/passwd mysql

#创建webserver目录,将nginx,php,mysql均安装到此目录
mkdir -p /usr/local/webserver

#创建mysql数据存放目录
mkdir -p /data0/mysql/3306/data/
mkdir -p /data0/mysql/3306/binlog/
mkdir -p /data0/mysql/3306/relaylog/
chown -R mysql:mysql /data0/mysql/

#开始安装mysql-5.5.20
tar zxvf mysql-5.5.20.tar.gz && cd mysql-5.5.20/
/usr/local/bin/cmake -DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/ \

#赋予shell脚本可执行权限
chmod +x /data0/mysql/3306/mysql

#启动MySQL
/data0/mysql/3306/mysql start

#通过命令行登录管理MySQL服务器
/usr/local/webserver/mysql/bin/mysql -u root -p

#创建一个具有root权限的用户(bingadmin)和密码(TQHQoYc55SR68S3M)
grant SELECT,INSERT,UPDATE,DELETE,CREATE,DROP,INDEX,ALTER,CREATE TEMPORARY TABLES on *.* to 'bingadmin'@'localhost' identified by 'TQHQoYc55SR68S3M';
grant SELECT,INSERT,UPDATE,DELETE,CREATE,DROP,INDEX,ALTER,CREATE TEMPORARY TABLES on *.* to 'bingadmin'@'127.0.0.1' identified by 'TQHQoYc55SR68S3M';
flush privileges;

说明:
1.每个数据库使用独立的数据库管理员,且分配如下权限(按实际分配):
select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file等14个权限
2.mysql数据库用户root密码必须修改
/usr/local/webserver/mysql/bin/mysqladmin -u root password n53s8mOE4Dh7qw

#停止MySQL命令
/data0/mysql/3306/mysql stop
service mysqld stop
/etc/init.d/mysqld stop

五、安装PHP
安装php所依赖的软件:
1.安装libiconv
tar xzvf libiconv-1.14.tar.gz && cd libiconv-1.14
./configure --prefix=/usr/local/webserver/lib/libiconv
make && make install && cd ../

2.安装libmcrypt
tar xzvf libmcrypt-2.5.8.tar.gz && cd libmcrypt-2.5.8
./configure
make && make install && cd ../

3.安装mhash
tar zxvf mhash-0.9.9.9.tar.gz && cd mhash-0.9.9.9
./configure
make && make install && cd ../

4.安装mcrypt
tar -zxvf mcrypt-2.6.8.tar.gz && cd mcrypt-2.6.8
LD_LIBRARY_PATH=/usr/local/lib ./configure
make && make install && cd ../

5.开始安装php
tar xzvf php-5.3.9.tar.gz && cd php-5.3.9
./configure --prefix=/usr/local/webserver/php \
--with-config-file-path=/usr/local/webserver/php/etc \
--with-mysql=/usr/local/webserver/mysql \
--with-mysqli=/usr/local/webserver/mysql/bin/mysql_config \
--enable-mbstring \
--with-libxml-dir=/usr/local/webserver/lib/libxml2 \
--with-iconv-dir=/usr/local \
--enable-fpm \
--with-zlib-dir=/usr/local/webserver/lib/zlib \
--enable-zip \
--with-mcrypt \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--enable-xml \
--with-gd \
--enable-gd-native-ttf \
--with-mhash

make
make install

**********************************
(1)找不到“-liconv”
/usr/bin/ld: cannot find -liconv
collect2: ld returned 1 exit status
make: *** [sapi/fpm/php-fpm] Error 1
解决办法:make ZEND_EXTRA_LIBS='-liconv'
(2)编译php错误/usr/bin/ld:cannot find -lltdl
错误提示是在./configure 后make的时候出现
/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
分析:
系统缺乏对应的库文件;
版本不对应;
库文件的链接错误;
库文件路径设置问题;

解决:
1)确认libltdl库文件是否存在
ll /usr/lib/libltdl*
ll /usr/lib/local/libltdl*
或者其他自定义的lib下有无libltdl.so
如果存在类似如libltdl.so.1,那么可以通过ln -sv libltdl.so.1 libltdl.so,建立一个连接重建libltdl.so
2)检查/etc/ld.so.conf中的库文件路径是否正确
可以直接将以下路径添加:
/usr/lib
/usr/local/lib

重建ld.so.cache文件:ldconfig

说明:重建ld.so.cache文件,ld的库文件检索目录存放文件。尤其刚刚编译安装的软件,必须运行ldconfig,才能将新安装的库文件导入ld.so.cache.
3)如果没有找到任何库文件,请执行下面
cd /tools/libmcrypt-2.5.8/libltdl
./configure --enable-ltdl-install
make && make install
*****************************************************

cp php.ini-production /usr/local/webserver/php/etc/php.ini
cp /usr/local/webserver/php/etc/php-fpm.conf.default /usr/local/webserver/php/etc/php-fpm.conf

#存放pid和日志文件
mkdir -p /usr/local/webserver/php/logs

vim /usr/local/webserver/php/etc/php-fpm.conf
修改内容为如下:
pid  /usr/local/webserver/php/logs/php-fpm.pid
error_log  /usr/local/webserver/php/logs/php-fpm.log

pm.max_children = 64 
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 1024
user = www
group = www 

************************************************************
安装PHP5扩展模块:
1.安装eaccelerator
tar jxvf eaccelerator-0.9.6.1.tar.bz2 && cd eaccelerator-0.9.6.1
/usr/local/webserver/php/bin/phpize
./configure --enable-eaccelerator=shared \
--with-php-config=/usr/local/webserver/php/bin/php-config
make && make install && cd ../

************************************************************
2.安装zend
wget http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-i386.tar.gz
tar zxvf ZendGuardLoader-php-5.3-linux-glibc23-i386.tar.gz
mv ZendGuardLoader-php-5.3-linux-glibc23-i386/php-5.3.x/ZendGuardLoader.so /usr/local/webserver/php/lib/php/extensions

#缓存目录,下面需要使用到此目录
mkdir -p /usr/local/webserver/eaccelerator_cache

vim /usr/local/webserver/php/etc/php.ini
按shift+g添加以下内容:
zend_loader.enable=1
zend_loader.disable_licensing=0
zend_loader.obfuscation_level_support=3
zend_loader.license_path=
zend_extension=/usr/local/webserver/php/lib/php/extensions/ZendGuardLoader.so

#启动php并验证
/usr/local/webserver/php/sbin/php-fpm
说明:启动php-fpm时出现ZendGuardLoader.so: cannot restore segment prot after reloc: Permission denied
关闭selinux即可,具体操作如下:
vim /etc/selinux/config
将SELINUX=enforcing 改成SELINUX=disabled
setenforce 0

ps -ef |grep php
netstat -anp |grep 127.0.0.1:9000

#设置nginx,mysql和php开机启动
vim /etc/rc.d/rc.local
