安装记录文件.txt

1、apt-get install gcc g++ make libssl-dev bison build-essential libncurses5-dev cmake autoconf m4
2、安装 pcre zlib


3、编译nginx
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-pcre=../pcre-8.00 --with-zlib=../zlib-1.2.11
make
make install

4、mysql安装,要输入两次密码
apt-get install mysql-server mysql-client
vi /etc/mysql/my.cnf
#bind-address = 127.0.0.1
修改数据库root的Host为%

5、php安装,php5需要ubuntu14.04以下
apt-get install libxml2 libxml2-dev

#因为前面安装了libssl-dev
ln -s /usr/lib/x86_64-linux-gnu/libssl.so  /usr/lib

apt-get install libjpeg-dev
ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so  /usr/lib

apt-get install libpng12-dev
ln -s /usr/lib/x86_64-linux-gnu/libpng.so  /usr/lib

apt-get install libfreetype6-dev
ln -sf /usr/include/freetype2 /usr/include/freetype2/freetype

apt-get install libmysqlclient-dev
ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so /usr/lib

wget http://php-fpm.org/downloads/php-5.2.17-fpm-0.5.14.diff.gz
gzip -cd php-5.2.17-fpm-0.5.14.diff.gz | patch -d php-5.2.17 -p1

报错：php-5.2.17/ext/dom/node.c:1953:21: error: dereferencing pointer to incomplete type     ret = buf->bu
解决：
curl -o php-5.2.17.patch https://mail.gnome.org/archives/xml/2012-August/txtbgxGXAvz4N.txt
cd php-5.2.17/
patch -p0 -b < ../php-5.2.17.patch
http://blog.csdn.net/moqiang02/article/details/19699557

报错:make: *** [sapi/cgi/php-cgi] Error 1
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
tar -zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1
./configure --prefix=/usr/local/libiconv-1.13.1
make && make install
接下来再编绎php的时候加上-–with-iconv=/usr/local/libiconv-1.13.1
http://blog.sina.com.cn/s/blog_998c49430101cp45.html

报错：php-5.2.17/ext/openssl/xp_ssl.c:357: undefined reference to `SSLv2_server_method'
php-5.2.17/ext/openssl/xp_ssl.c:337: undefined reference to `SSLv2_client_method'
这个需要一个补丁禁用openssl的SSLv2_client_method，方法如下：
wget http://www.centos.bz/wp-content/uploads/2012/06/debian_patches_disable_SSLv2_for_openssl_1_0_0.patch
cd php-5.2.17/
patch -p1 < ../debian_patches_disable_SSLv2_for_openssl_1_0_0.patch

报错：Please reinstall the libcurl distribution - easy.h should be in <curl-dir>/include/curl/
apt-get install libcurl4-gnutls-dev

error: mcrypt.h not found. Please reinstall libmcrypt.
下载lib包 https://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/
#解压
tar -zxvf libmcrypt-2.5.8.tar.gz
#进入目录
cd libmcrypt-2.5.8
#编译（默认安装到/usr/local/lib/）
./configure --prefix=/usr/local/libmcrypt-2.5.8
#执行安装
make && make install

sudo ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-mbstring --with-mcrypt=/usr/local/libmcrypt-2.5.8 --enable-ftp --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --with-mysql=/usr/bin/ --with-mysqli=/usr/bin/mysql_config --with-openssl-dir=/usr --with-openssl --with-pdo-mysql --with-pear --enable-sockets --with-freetype-dir=/usr --enable-gd-native-ttf --with-zlib --with-libxml-dir=/usr --with-xmlrpc --enable-zip --enable-fastcgi --enable-fpm --enable-xml --enable-sockets --with-gd --with-zlib --with-iconv=/usr/local/libiconv-1.13.1 --enable-zip --with-freetype-dir=/usr/lib/ --enable-soap --enable-pcntl --enable-cli --with-curl

完成后需要修改
strip /usr/local/php/bin/php-cgi
cp php.ini-recommended /usr/local/php/lib/php/php.ini


vi /etc/php5/etc/php-fpm.conf
<!-- <value name="user"></value> -->
<!-- <value name="group">nobody</value> -->
默认与nginx.conf 用户名 一致，都为nobody修改为：
<value name="user">nobody</value>
<value name="group">nobody</value>

修改项目目录权限
chmod -R 777 mobile/data/compiled
chmod -R 777 wapMobile/data/caches

添加扩展：
扩展包路径执行
/usr/local/php/bin/phpize
./configure --enable-shared --with-php-config=/usr/local/php/bin/php-config
make && make install


添加在php.ini  Dynamic Extensions里面，注意路径，（5.4以下版本可用）
extension="lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="128"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter="*.php"
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"

;这里是control.php所有的目录,control.php在安装包里面需要拷贝到此目录，用户与密码在文件内
eaccelerator.allowed_admin_path="/dtw/wwwroot/shop/"

如果nginx无法打开php查看nginx日志，
问题：静态页面可以打开，php页面无法加载。upstream timed out (110: Connection timed out) while connecting to upstream
解决：-A INPUT -i lo -j ACCEPT 这条更合理 -A INPUT -p tcp -m tcp --dport 9000 -j ACCEPT

nginx静态资源缓存：
#静态文件，nginx自己处理
location ~ ^/(images|javascript|js|css|flash|media|static)/ {
    #过期30天，静态文件不怎么更新，过期可以设大一点，
    #如果频繁更新，则可以设置得小一点。
    expires 30d;
}
location ~ ^/mobile/(images|img|javascript|js|css|flash|media|static)/ {
    expires 30d;
}
location ~ .*\.(gif|jpg|png|htm|html|css|js|flv|ico|swf)(.*) {
    expires 30d;
}

安装ab: apt-get install apache-utils
如果运行报错就需要手动安装了
apt-get install libtool autoconf automake
rm: cannot remove 'libtoolT': No such file or directory
直接打开apr-1.6.2/configure  把 $RM "$cfgfile" 那行删除掉
$RM "$cfgfile"  大约在 42302 行

问题：no package 'apr-1' found ubuntu
解决：apt-get install libapr1 libapr1-dev
https://stackoverflow.com/questions/22075531/how-to-install-apr-in-ubuntu

apt-get install libexpat1-dev
