创业阶段，进一步实践了Linux环境搭建和维护，以下是一些经常使用软件的搭建步骤和參考资料，仅供自己和诸位參考。

我个人还是比較倾向“一站式Web开发”的。自己想做点事。须要太多的技能。

非商业软件项目，自己全盘负责比較灵活和高效。

1.mysql（关键是创建mysql用户，并用mysql用户运行安装程序）
參考资料 http://www.cnblogs.com/xiaoluo501395377/archive/2013/04/07/3003278.html
rpm -qa | grep mysql　　// 这个命令就会查看该操作系统上是否已经安装了mysql数据库

Mysql下载地址
http://dev.mysql.com/downloads/file.php?id=451491

----------------------
./mysqld_safe --user=mysql &

不能直接使用mysqld。以root用户的身份运行（--user=mysql。能够解决问题）
2014-04-24 09:19:50 8011 [ERROR] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!

./bin/mysqld --user=mysql &
不要使用root用户。使用mysql用户

mysql启动
http://swordshadow.iteye.com/blog/1921814

//这样的方式，有时候，不起作用，直接按Enter，mysql就被杀死了
./mysqld --user=mysql &

能够使用nohup命令启动
nohup /usr/bin/mysql --user=mysql &
------------------------
启动报错

2014-04-24 09:25:09 8276 [Note] InnoDB: 128 rollback segment(s) are active.
InnoDB: Error: pthread_create returned 11

暂时解决方法：

# ulimit -s unlimited

./mysqld_safe: line 166: 8796 Killed
nohup /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/data/AY1404221737304200fcZ.err --pid-file=/usr/local/mysql/data/AY1404221737304200fcZ.pid < /dev/null >> /usr/local/mysql/data/AY1404221737304200fcZ.err 2>&1
140424 09:35:47 mysqld_safe Number of processes running now: 0

mysqld --basedir=/usr/local/mysql --datadir=/var/lib/mysql --user=mysql &

该方法在系统重新启动，或者又一次登录后将失效。

第二种方法:

改动/etc/profile文件，加入

ulimit -s unlimited
---------------卸载自带的mysql---------------
rpm -qa |grep mysql
卸载centos自带的mysql，rpm -e --nodeps mysql-libs-5.1.61-4.el6.x86_64

------------------------------------

2014-04-24 11:17:25 14210 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

2.Redis配置
http://hi.baidu.com/cxc0378/item/40f4b70e7fda603af3eafcbb

3.Mongodb
/usr/local/mongodb/start-mongo

4.node
下载二进制安装包。解压就可以

export NODE_HOME=/usr/local/node/
export PATH=$NODE_HOME/bin:$PATH

Linux下运行，
./node

//使用绝对路径
forever start /var/www/trunk/bootstrap.js &
forever stop /var/www/trunk/bootstrap.js &

forever start -l /var/www/snsforever.log -o /var/www/snsout.log -e /var/www/snserr.log /var/www/sns/bootstrap.js
forever stop /var/www/sns/bootstrap.js
-------------------------------------------------------------------------
关键：使用mysql用户
[mysql@itfriend mysql]$ scripts/mysql_install_db --user=mysql --basedir=/home/mysql/mysql --datadir=/home/mysql/mysql/data

server内存太小，没有交换区，手动改动
http://www.prowebdev.us/2012/05/amazon-ec2-linux-micro-swap-space.html

Run dd if=/dev/zero of=/swapfile bs=1M count=1024
Run mkswap /swapfile
Run swapon /swapfile
Add this line /swapfile swap swap defaults 0 0 to /etc/fstab

5.Nginx
下载地址 http://nginx.org/download/，都是源代码包，没有二进制安装包

安装过程
wget http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
yum install nginx-release...
yum install nginx

[root@itfriend bin]# find / -name nginx
/var/cache/yum/x86_64/6/nginx
/var/cache/nginx
/var/log/nginx
/var/lib/yum/repos/x86_64/6/nginx
/usr/share/nginx
/usr/sbin/nginx
/etc/sysconfig/nginx
/etc/logrotate.d/nginx
/etc/rc.d/init.d/nginx
/etc/nginx

启动 nginx

又一次载入
nginx -s reload

停止1
nginx -s quit

停止2
ps -ef|grep enigx，找到master的进程号
kill -QUIT 24346

静态资源被Ngnix拦截，直接响应浏览器
http://114.215.191.169/images/fans123/photos/44813db99c67489523bd7edfb14e1bed7b7553a8.gif

參考资料：
http://nginx.org/en/linux_packages.html
http://www.nginx.cn/

6.Linux命令
改动密码： passwd root,输入2次密码

/usr/local/mysql/bin/mysqld_safe --user=mysql
cat /var/log/mysqld.log

mysqladmin -u root password "11"

/usr/local/mysql/bin/mysqladmin -u root password 11

source/etc/profile是让/etc/profile文件改动后马上生效

：tar zxvf

7.crontab
crontab -e
编辑自己这个用户的定时文件

*/1 * * * * /var/www/autobackup-mysql.sh
每分钟运行一次

8.安装JDK
查看可安装的java包yum list java*
yum install java-1.7.0-openjdk* -y
