查看一下网卡信息确认是否已经配置好
（二）
然后进行下一步，安装nginx，可以到官网下载，找到稳定版
打开/etc/apt/source.list文件，将下面两行命令粘贴到文件的末尾，不要粘错了！！
deb http://nginx.org/packages/ubuntu/ codename nginx
deb-src http://nginx.org/packages/ubuntu/ codename nginx
将以下配置写到配置文件中
[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
datadir = /Disk/data/mysql/var
port = 3306
socket = /tmp/mysql.sock
skip-external-locking
key_buffer_size = 256M
max_allowed_packet = 20M
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 8M
myisam_sort_buffer_size = 64M
#server-id = 1
#xzy
thread_stack = 192K
thread_cache_size = 64
myisam-recover = BACKUP
max_connections = 5000
query_cache_limit = 2M
query_cache_size = 256M
#错误日志记录
log_error = /Disk/log/mysql/error.log
#慢查询日志
#slow-query-log = /Disk/log/mysql/mysql-slow.log
#long_query_time = 5
#log-queries-not-using-indexes
#二进制文件日志
log_bin = /Disk/log/mysql/mysql-bin.log
binlog_format = row
expire_logs_days = 10
max_binlog_size = 100M
#不区分大小写
lower_case_table_names=1
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
no-auto-rehash
[myisamchk]
key_buffer_size = 256M
sort_buffer_size = 256M
read_buffer = 2M
write_buffer = 2M
[mysqlhotcopy]
interactive-timeout
接下来我们修改一下/etc/profile文件将这句话加到文件末尾，把mysql服务加入系统环境变量
export PATH=$PATH:/Disk/local/mysql/bin
再输入密码就能登录进行数据库的操作了
我们用windows下的Natcivat连接服务器Mysql，出现1130错误提示，是因为远程服务器无权限登录MySQL
对root用户授权并设置密码
mysql> grant all on *.* to 'root'@'%' identified by '888888';
然后将PHP和nginx进行整合，修改默认配置文件 ,将下面的代码取消注释
12345678 root@ubuntu:/etc/nginx/conf.d# vim default.conf
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
用浏览器访问http://主机地址/upload/install/index.php
进入discuz安装首页进行安装，填写主机名，数据库密码，管理员密码
安装成功后用管理员登录就可以了
