5)修改php.ini文件
手工修改:查找/usr/local/php/etc/php.ini中的extension_dir = "./"修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行,然后保存:
1
2
3
|
extension = "memcache.so" extension = "pdo_mysql.so" extension = "imagick.so" |
再查找; cgi.fix_pathinfo=0 修改为cgi.fix_pathinfo=0,
防止Nginx文件类型错误解析漏洞。
注:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改:
1

4
|
sed -i ‘s#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#‘ /usr/local/php/etc/php .ini sed -i ‘s#output_buffering = Off#output_buffering = On#‘ /usr/local/php/etc/php .ini sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/php/etc/php .ini sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/php/etc/php .ini |
7)创建www用户和组,以及供book.zhiyin.com和www.zhiyin.com两个虚拟主机使用的目录:

8) 创建Nginx日志目录
1
2
3
|
mkdir -p /var/log/nginx chmod +w /var/log/nginx chown -R www:www /var/log/nginx |
4) 创建Nginx配置文件
①在/usr/local/nginx/conf/目录中创建nginx.conf文件:
1
2
|
rm -f /usr/local/nginx/conf/nginx .conf vi /usr/local/nginx/conf/nginx .conf |

5)启动Nginx

ulimit -SHn 65535 /usr/local/php/sbin/php-fpm start /usr/local/nginx/sbin/nginx /var/mysql/mysql start |
5 在不停止Nginx服务的情况下平滑变更Nginx配置
1)修改
/usr/local/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:
1
|
/usr/local/nginx/sbin/nginx -t |
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
2) 平滑重启:
①、对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可:
1
|
/usr/local/nginx/sbin/nginx -s reload |
1
|
ps -ef | grep "nginx: master process" | grep - v "grep" | awk -F ‘ ‘ ‘{print $2}‘ |
1
|
kill -HUP 6302 |
1
|
kill -HUP ` cat /usr/local/nginx/nginx .pid` |
