1. 如何允许laravel程序执行sudo shell脚本?
 chmod u+w /etc/sudoers ; 
    echo "apache ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers
    再注释掉Defaults requiretty这行,否则会要求有tty才能运行!(TODO: 写shell实现自动化)
    chmod u-w /etc/sudoers
2. OS: CentOS 7.2 x64
3. 安装zend server ce: (由于zend现在修改了策略开始收费,我们必须自己搭建环境了!)
	tar xvfz ZendServer-8.0.2-RepositoryInstaller-linux.tar.gz
	cd ZendServer-8.0.2-RepositoryInstaller-linux
	./install_zs.sh 5.6
4. 常用其他命令: 
	yum search php-  :列出所有php-的包	
	yum search git  :列出所有git的包	
	yum info git.x86_64  : 列出git.x86_64的包的细节,比如版本信息,如果太老,可能需要重新安装
	由于通过查看yum info php.x86_64发现版本是很低的,因此要用PHP5.6以上我们必须自己build
5. 从源代码build安装git
	rpm -qa |grep git /列出所有已经安装的包含git字符串的包
	由于git默认版本太老1.8.x我们需要erase掉(但是要注意其erase时会把dependency也清除掉)
	yum erase git-1.8.3.1-6.el7_2.1.x86_64
    yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
    yum install  gcc perl-ExtUtils-MakeMaker
    cd /usr/src
	wget https://www.kernel.org/pub/software/scm/git/git-2.0.4.tar.gz	
	tar xzf git-2.0.4.tar.gz
	cd git-2.0.4
	
	make prefix=/usr/local/git all
	make prefix=/usr/local/git install
	echo "export PATH=/usr/local/git/bin:$PATH" >> /etc/bashrc
	source /etc/bashrc
	git --version
6. 安装apache
	yum install httpd
	systemctl start httpd.service (注意以前的service httpd restart已经全部改为systemctrl 动作 服务名.service 了!)
	测试 http://localhost 确认apache已经正确启动
	systemctl enable httpd.service   // 开机启动httpd
	systemctl disable httpd.service   // 禁止开机启动httpd
	// apache的一些modules都放在 /usr/lib54/httpd/目录下,有可能部分没有默认安装,  Cannot load modules/mod_authn_alias.so ,解决办法:(暂时注释掉了)
	// AH00548: NameVirtualHost has no effect and will be removed in the next release: 从2.4开始已经不需要这个NameVirtualHost directive了
	apachectl -v // 显示版本信息 Server version: Apache/2.4.6 (CentOS) Server built:   Nov 14 2016 18:04:44
    // 新版本apche一个虚拟主机配置如下:
    "	
<VirtualHost *:80>
    ServerAdmin admin@kidsit.cn
    DocumentRoot /assets/www/newkidsitl5229/public/
    ServerName kidsit.cn
    #ServerAlias *.kidsit.cn
    ErrorLog logs/kidsit_staging.error_log
    CustomLog logs/kidsit_staging.access_log common
    <Directory /assets/www/newkidsitl5229/public/>
        DirectoryIndex index.html index.php
		AllowOverride All  // 注意这个用来控制允许.htaccess文件被apache使用 rewrite的!
        Require all granted
    </Directory>
</VirtualHost>
	"
	apachectl -M // 列出apache已经加载的so(shared object以LoadModule的方式加载进来的)
	apachectl -l // 列出compiled in module
	ServerName kidsit.cn:80  // 虽然不设置没有什么大的问题,但是会在systemctl status -l httpd.service中出现一个错误(虽然不影响使用)
	
7. 安装mysql
    注意:由于centos7自带mariadb,而不再自带mysql,因此你直接运行yum install mysql-server会报找不到mysql,方法:
    rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm // 这个是myslq的repo,安装之后yum search mysql就能看到mysql-community-server了
    yum install mysql-community-server       // 只能安装mysql-community-server了,因为oracle收购mysql后,搞了多种license为了收钱
	systemctl start mysqld.service
	systemctl enable mysqld.service
	mysql -uroot -p // 默认没有密码,登录进去后再修改密码
	set password for ‘root‘@‘localhost‘ =password(‘guozhiyindba@01‘);
8. 安装PHP
	yum install git gcc gcc-c++ libxml2-devel pkgconfig openssl-devel bzip2-devel curl-devel libpng-devel libjpeg-devel libXpm-devel freetype-devel gmp-devel libmcrypt-devel mariadb-devel aspell-devel recode-devel autoconf bison re2c libicu-devel httpd-devel
	// 注意httpd-devel是用来包含apxs2工具的,否则无法build出libphp7.so文件来
	yum install bzip2 // 该命令安装bzip2小工具,用于tar -xjv .bz2文件解压
	wget http://cn2.php.net/distributions/php-7.1.0.tar.bz2
	tar -xjf php-7.1.0.tar.bz2  // 解压
	cd php-7.1.0
	
	// 下面的命令将configure php with basic extension,并且为build做准备
	./configure --help //列出所有你可以选择的extension功能开关
	"
[root@iZuf61xke8lva2rsqr9vp3Z php-7.1.0]# ./configure --help
`configure‘ configures this package to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...‘ messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache‘
  -n, --no-create         do not create output files

                          following for Sybase SQL Anywhere 5.5.00 on QNX, prior to
                          running this configure script:
                            CPPFLAGS=\"-DODBC_QNX -DSQLANY_BUG\"
                            LDFLAGS=-lunix

  --enable-pcntl          Enable pcntl support (CLI/CGI only)
  --disable-pdo           Disable PHP Data Objects support
  --with-pdo-dblib=DIR    PDO: DBLIB-DB support.  DIR is the FreeTDS home directory
  --with-pdo-firebird=DIR PDO: Firebird support.  DIR is the Firebird base
                          install directory /opt/firebird
  --with-pdo-mysql=DIR    PDO: MySQL support. DIR is the MySQL base directory
                          If no value or mysqlnd is passed as DIR, the
                          MySQL native driver will be used
  --with-zlib-dir=DIR     PDO_MySQL: Set the path to libz install prefix
  --with-pdo-oci=DIR      PDO: Oracle OCI support. DIR defaults to \$ORACLE_HOME.
                          Use --with-pdo-oci=instantclient,prefix,version
                          for an Oracle Instant Client SDK.
                          For example on Linux with 11.2 RPMs use:
                            --with-pdo-oci=instantclient,/usr,11.2
                          With 10.2 RPMs use:
                            --with-pdo-oci=instantclient,/usr,10.2.0.4
  --with-pdo-odbc=flavour,dir
                          PDO: Support for ‘flavour‘ ODBC driver.
                          include and lib dirs are looked for under ‘dir‘.
                          ‘flavour‘ can be one of:  ibm-db2, iODBC, unixODBC, generic
                          If ‘,dir‘ part is omitted, default for the flavour
                          you have selected will be used. e.g.:
--with-pdo-odbc=unixODBC
                          will check for unixODBC under /usr/local. You may attempt
                          to use an otherwise unsupported driver using the \"generic\"
                          flavour.  The syntax for generic ODBC support is:
--with-pdo-odbc=generic,dir,libname,ldflags,cflags
                          When built as ‘shared‘ the extension filename is always pdo_odbc.so
  --with-pdo-pgsql=DIR    PDO: PostgreSQL support.  DIR is the PostgreSQL base
                          install directory or the path to pg_config
  --without-pdo-sqlite=DIR
                          PDO: sqlite 3 support.  DIR is the sqlite base

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  YACC        The `Yet Another Compiler Compiler‘ implementation to use.
              Defaults to the first program found out of: `bison -y‘, `byacc‘,
              `yacc‘.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d‘ given by some make applications.
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  CXXCPP      C++ preprocessor
Use these variables to override the choices made by `configure‘ or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to the package provider.
