// mysql数据目录迁移
1. service mysqld stop
2. 在/app 下新建一个目录mysqldir : mkdir mysqldir #在新分区上建立mysqldir目录
3. cd /usr/local/mysql && cp -r /app/mysqldir 新数据拷到新目录mysqldir下
4. rm -rf mysql //把原来的数据目录删掉
5 ln -s /app/mysqldir mysql
6. service mysqld start
本以为没啥问题,运行第6条命令后发现mysql起不来,所如下错误:
Starting MySQL. ERROR! Thequit without updating PID file (/usr/local/mysql/data/AY13121220352352963dZ.pid).
运行service mysqld status输出如下提示信息:
ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql) exists
ok 这个问题应该很常见了,我的解决办法是运行如下命令:
1. chown -R mysql:mysql /app/mysqldir #设置新目录权限归mysql用户所有
2. rm -f /var/lock/subsys/mysql
再执行service mysqld start 大功告成
这时候有可能还不行,这是要关闭selinux
1、vi /etc/selinux/config 将中的SELINUX=enforcing改成SELINUX=disabled,然后保存,这时候的selinux是没有生效的,要重启mysql后才会生效
#SELINUX=enforcing
SELINUX=disabled
2、执行setenforce 0
3、执行sestatus -v,查看2操作是否生效
4、启动mysql,这样就ok了

补充:做软链接
如果这一步不做,mysql可以启动,但是网站的数据库链接会报错:
Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'
做链接的命令如下:
ln -s /usr/mysql/mysql.sock /var/lib/mysql/mysql.sock
最后,打开mysql服务,一切OK


【注意】,更改mysql的sock目录后,可能原来的php链接mysql会失败,因为php.ini中的mysql.default_socket = 是默认是没有设置路径的,这是后需要将php.ini中的mysql.default_socket = /opt/mysql/mysql.sock(迁移mysql后的sock路径,同/etc/my.conf中的路径)
然后在重启php-fpm,service php-fpm start

// linux 安装sqlite
1.源码安装步骤如下:
1)wget http://www.sqlite.org/sqlite-3.5.6.tar.gz
2)tar -xzvf sqlite-3.5.6.tar.gz
3)cd sqlite-3.5.6
4)./configure --disable-tcl ##加上这个选项则不需要TCL,否则在2.4内核上编译通不过
5)make
6)make install

2.测试是否安装成功
# cd /usr/lcoal/bin
# ./sqlite3 text.db
如果安装成功,会出现下面这样的信息
SQLite version 3.5.6
Enter ".help" for instructions

vi /etc/hosts
添加 Beijingny003

通过vi /etc/security/limits.conf 添加如下配置参数:修改之后保存,注销当前用户,重新登录,通过ulimit -a 查看修改的状态是否生效。

* soft  nofile  1000000
* hard  nofile  1000000
需要指出的是,尽管我们可以将单个进程打开的最大句柄数修改的非常大,
但是当句柄数达到一定数量级之后,处理效率将出现明显下降,因此,需要根据服务器的硬件配置和处理能力进行合理设置。如果单个服务器性能不行也可以通过集群的方式实现。

Mac安装Brew
安装命令如下:
curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1

当brew安装成功后,就可以随意安装自己想要的软件了,例如wget,命令如下:
sudo brew install wget

卸载的话,命令如下:
sudo brew uninstall wget

查看安装软件的话,命令如下:
sudo brew search /apache*/

注意/apache*/是使用的正则表达式,用/分割。

// jdk安装
rpm -ivh jdk-7u25-linux-x64.rpm
vi /etc/profile
export JAVA_HOME=/usr/java/jdk1.7.0_25
PATH=$JAVA_HOME/bin:$PATH
source /etc/profile

// mono
網上說安裝Mono之前必須要先安裝這些包:
gcc gcc-c++ bison pkgconfig glib2-devel gettext make libpng-devel libjpeg-devel libtiff-devel libexif-devel giflib-devel libX11-devel freetype-devel fontconfig-devel cairo-devel
由於本人在安裝CentOS 6.3的時候選擇的是Development模式,想必這些包都已經默認安裝在內了,但為了安全起見還是使用rpm命令對其一個個做了檢測確保已經安裝過,檢測命令大致如下:
# rpm -qa libexif*
經過一輪檢測,發現確實有幾個漏網之魚,遂使用 yum install 將其一一安裝到位。
下載安裝mono 3.0.12
# cd /usr/local/src
wget http://download.mono-project.com/sources/libgdiplus/libgdiplus-2.10.tar.bz2
tar -jxvf libgdiplus-2.10.tar.bz2
cd libgdiplus-2.10
./configure --prefix=/usr
make && make install
# wget http://download.mono-project.com/sources/mono/mono-3.0.12.tar.bz2
# tar -jxvf mono-3.0.12.tar.bz2
# cd mono-3.0.12
# ./configure --prefix=/usr
# make && make install
漫長的等待之後,調用下mono看看吧。進入/usr/lib/mono 目錄就可以看到熟悉的.NET程序集咯...

解决no input file specifiled
1、更改php.ini cig.fix_pathinfo=0改为cig.fix_pathinfo=1


开发步骤
git clone http://10.128.112.2:3000/droi/lua.git
git add 修改過的檔案
git commit –m ‘修改檔案註釋’
git push这时候输入账号密码,文件提交成功

git建库
git clone git@120.26.224.211:/opt/git/pingku.git

check
curl -X POST -H "Content-Type:application/json"​ -d @input.json http://10.128.112.80:8000/add.lua
