#linux软件安装时，除了二进制包外可能还需要该软件的-devel包
[pikaqiu@bogon nginx]$ wget http://nginx.org/download/nginx-1.8.0.tar.gz
配置参数，http_stub_status_module为nginx的统计模块(有openssl,zlib,prec的前置条件,且安装路径分别为:/usr/local/web/openssl，默认路径(未手动指定)，/usr/local/web/prec)
./configure --prefix=/usr/local/web/nginx/ --with-http_stub_status_module --with-pcre=/root/soft/pcre-8.38 --with-openssl=/usr/local/web/openssl/include/openssl --with-zlib=/usr/local/web/zlib/include
注：nginx1.10.0安装时，配置里的pcre必须为pcre的源码目录，如果with-pcre里的路径为安装后的目录时，会报找不到文件夹的错误；zlib必须默认安装，且configure时不能加zlib的with项，如果安装时手动指定了目录，就算安装时在with里指定了安装目录，也会产生一个make: *** No rule to make的make错误；另外，zilb和nginx的gzip压缩有关，nginx默认安装时如果没有安装zlib，configure时会产生一个需要zlib的错误，但错误提示里有一个用with配置将zlib关闭的选项；
#启用该统计模块时需配置nginx的配置文件，示例(该示例中只允许192.168.0.101该IP访问该模块)：
location /status {
stub_status on;
access_log off;
allow 192.168.0.101;
deny all;
}
启动nginx
#直接执行sbin目录下的nginx就能启动ngninx，另外，netstat -antp可以查看端口被哪个程序占用
[root@bogon pikaqiu]# /usr/local/nginx/sbin/nginx [root@bogon pikaqiu]# netstat -antp
nginx信号控制
Nginx中使用信号来控制Nginx停止、平滑重启，Nginx支持以下几种信号：
1）TERM，INT快速关闭 SIGINT SIGTERM 即：NGX_TERMINATE_SIGNAL and SIGINT
2）QUIT 从容关闭 SIGQUIT 即 NGX_SHUTDOWN_SIGNAL
3）HUP 平滑重启，重新加载配置文件 SIGHUP 即NGX_RECONFIGURE_SIGNAL
4）USR1 重新打开日志文件，在切割日志时用途较大 SIGUSR1 即NGX_REOPEN_SIGNAL
5）USR2 平滑升级可执行程序 SIGUSR2 即NGX_CHANGEBIN_SIGNAL
6）WINCH 从容关闭工作进程
nginx平滑重启
[root@bogon html]# ps aux|grep nginx root 8572 0.0 0.0 24308 752 ? Ss 13:39 0:00 nginx: master process /usr/local/nginx/sbin/nginx nobody 8573 0.0 0.0 26820 1748 ?

配置文件更改过后HUP
[root@bogon html]# ps aux|grep nginx root 9149 0.0 0.0 24308 764 ? Ss 14:06 0:00 nginx: master process /usr/local/nginx/sbin/nginx nobody 9150 0.0 0.0 26820 1508 ?

利用logs/nginx.pid获取nginx正在使用的进程号
[root@bogon logs]# kill -HUP `cat /usr/local/nginx/logs/nginx.pid`
MYSQL安装(rpm方式)(5.6.17下载地址：http://www.360sdn.com/opensource-datasource/2014/0410/2940.html)
检测并删除已有的MYSQL
[root@iZ28mhfkaunZ mysql]# rpm -qa|grep -i mysql [root@iZ28mhfkaunZ mysql]# rpm -e mysql
MYSQL安装，server为服务器，devel为所需的库和包含文件。如果你想要编译其他MySQL客户程序, 例如Perl模块。client客户端；
[root@iZ28mhfkaunZ mysql]# rpm -ivh MySQL-server-5.6.17-1.linux_glibc2.5.x86_64.rpm [root@iZ28mhfkaunZ mysql]# rpm -ivh MySQL-devel-5.6.17-1.linux_glibc2.5.x86_64.rpm [root@iZ28mhfkaunZ mysql]# rpm -ivh MySQL-client-5.6.17-1.linux_glibc2.5.x86_64.rpm
配置文件复制
[root@iZ28mhfkaunZ mysql]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
MYSQL的默认安装路径
[root@iZ28mhfkaunZ mysql]# find / -name mysql /usr/bin/mysql /usr/include/mysql /usr/include/mysql/mysql /usr/lib64/mysql /usr/share/mysql /etc/logrotate.d/mysql /etc/rc.d/init.d/mysql /root/soft/mysql /var/lib/mysql /var/lib/mysql/mysql
注：如果安装时出现如下情况，说明系统已经安装了其他版本的mysql-libs包导致不兼容；需先删除mysql-libs，再进行安装

[root@iZ28mhfkaunZ mysql]# yum list | grep mysql [root@iZ28mhfkaunZ mysql]# yum remove mysql-libs
初始化MySQL及设置密码
[root@iZ28mhfkaunZ mysql]# /usr/bin/mysql_install_db
[root@iZ28mhfkaunZ mysql]# service mysql start
[root@iZ28mhfkaunZ mysql]# cat /root/.mysql_secret #冒号后面的为密码
