....... mysql 初始化报错，发现网上有哥们已经解决了这个问题，实在是强大，原因是my.cnf中有一行： thread_concurrency = 8
thread_concurrency这个变量，意思是并发的线程数，并且根据给的解释是该参数取值为服务器逻辑CPU数量×2，而如果每颗物理CPU又支持H.T超线程，所以实际取值为4 × 2 ＝ 8。而我这个机器是ADM闪龙3000 单核的CPU，并不符合它的要求，所以它提示“unknown variable ‘thread_concurrency=8′”是个未知变量。对my.cnf做一些修改，把’thread_concurrency=8′注释掉 重新初始化OK [root@mgmserver mysql]# bin/mysql_install_db --user=mysql

Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/ (5)、修改php.ini文件
找到491行的extension_dir = "./"
修改为 extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613" 指定模块所在的位置；
在这行后面加上
493 extension = "imagick.so"
494 extension = " memcache.so"
495 extension = "pdo_mysql.so"
在 101行处
修改 output_buffering = Off为 output_buffering = On
把523 处的注释去掉， cgi.fix_pathinfo=0 防止nginx文件类型错误解析漏洞 6、配置php加速eaccelerator
创建缓存文件夹;
[root@mgmserver local]# mkdir eaccelerator_cache
在php.ini配置文件末尾加上如下：
1290 [eaccelerator]
1291 extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so
1292 eaccelerator.shm_size="32"
1293 eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
1294 eaccelerator.enable="1"
1295 eaccelerator.optimizer="1"
1296 eaccelerator.check_mtime="1"
1297 eaccelerator.debug="0"
1298 eaccelerator.filter=""
1299 eaccelerator.shm_max="0"
1300 eaccelerator.shm_ttl="3600"
1301 eaccelerator.shm_prune_period="360"
1302 eaccelerator.shm_only="0"
1303 eaccelerator.compress="1"
1304 eaccelerator.compress_level="9" （7）、悲剧了，空余的机器被拿去用了，只好换个机器，创建www 用户和组，及两个虚拟主机域名目录www.nginx.com与web.nginx.com
[root@mgmserver ~]# groupadd www
[root@mgmserver ~]# useradd -g www www
[root@nginx ~]# mkdir -p /web/htdocs/www.nginx.com
[root@nginx ~]# chown -R www:www /web/htdocs/www.nginx.com
[root@nginx ~]# mkdir -p /web/htdocs/web.nginx.com
[root@nginx ~]# chown -R www:www /web/htdocs/web.nginx.com/

把配置文件的63行和66行修改如下：
62 Unix user of processes
63 www
64
65 Unix group of processes
66 www
切记要把63行和66行的注释符号去掉不然在启动时会出错的！

........ 3、安装nginx (1)、安装nginx及所需要的pcre库
[root@nginx pcre-8.10]# ./configure
[root@nginx pcre-8.10]# make
[root@nginx pcre-8.10]# make install
[root@nginx install_packet]# cd nginx-0.8.48/
[root@nginx nginx-0.8.48]# ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
[root@nginx nginx-0.8.48]#make
[root@nginx nginx-0.8.48]#make install （2）、创建nginx的日志文件
[root@nginx /]# mkdir -p web/nginxlogs
[root@nginx /]# chmod +w web/nginxlogs/
[root@nginx /]# chown -R www:www web/nginxlogs/ （3）、修改nginx的配置文件如下：
1
2 user www www;
3 worker_processes 1;
4 error_log /web/nginxlogs/error.log crit;
5 pid /usr/local/nginx/nginx.pid;
6 worker_rlimit_nofile 65535;

87 access_log /web/nginxlogs/webaccess.log webaccess;
88 }
89 } （4）、保持conf/下fastcgi.conf配置文件不变就可以了 （5）、启动nginx
[root@nginx nginx]#/usr/
[root@nginx nginx]# /usr/local/nginx/sbin/nginx (6)、开机启动nginx 与php
[root@nginx nginxlogs]# vi /etc/rc.local
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx
(7)修改文件中先检查配置文件是否正确，然后在启动
[root@nginx nginxlogs]# /usr/local/nginx/sbin/nginx -t
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@nginx nginxlogs]# kill -HUP `cat /usr/local/nginx/nginx.pid`
或者
[root@nginx nginxlogs]# /usr/loca/nginx/sbin/nginx -s> 4、测试
在www.nginx.com的文档目录中
[root@nginx www.nginx.com]# vi index.php/
