Nginx安装设置+清缓存模块安装

颠末一段时间的利用，发明nginx在并发与负载本领方面确实优于apache，香港网存空间北京主机，此刻已经将大部门站点从apache转到了nginx了。以下是nginx的一些简朴的安装设置。

情况

操纵系统：CentOS、RedHat

IP地点：192.168.1.202

下载软件包

# mkdir /usr/local/src/tarbag

# mkdir /usr/local/src/software

# cd /usr/local/src/tarbag/

Nginx

# wget http://www.nginx.org/download/nginx-1.0.6.tar.gz

Nginx cache purge模块(可选)

# wgethttp://labs.frickle.com/files/ngx_cache_purge-1.3.tar.gz

编译安装

# cd /usr/local/src/tarbag/

# tar -xzvf nginx-1.0.6.tar.gz -C /usr/local/src/software

# tar -xzvf ngx_cache_purge-1.3.tar.gz -C/usr/local/src/software

# cd /usr/local/src/software/

# ./configure

–prefix=/usr/local/nginx-1.0.6 #安装路径

–with-http_stub_status_module #启用nginx状态模块

–with-http_ssl_module #启用SSL模块

–with-http_realip_module #启用realip模块（将用户IP转发给后端处事器）

–add-module=../ngx_cache_purge-1.3 #添加缓存排除扩展模块

# make

# make install

内核参数优化

# vi sysctl.conf增加以下设置

net.ipv4.netfilter.ip_conntrack_tcp_timeout_established =1800

net.ipv4.ip_conntrack_max = 16777216　＃　假如利用默认参数,容易呈现网络丢包

net.ipv4.netfilter.ip_conntrack_max =16777216＃　假如利用默认参数,容易呈现网络丢包

net.ipv4.tcp_max_syn_backlog = 65536

net.core.netdev_max_backlog =32768

net.core.somaxconn = 32768

net.core.wmem_default = 8388608

net.core.rmem_default = 8388608

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0

net.ipv4.tcp_synack_retries = 2

net.ipv4.tcp_syn_retries =

net.ipv4.tcp_tw_recycle = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000

net.ipv4.tcp_max_orphans = 3276800

net.ipv4.ip_local_port_range = 102465535

设置生效

# sysctl –p

修改iptables启动剧本,在star()函数内里加上

# vi /etc/init.d/iptables

/sbin/sysctl -p

设置典型站点站点

序号

域名

目次

1

www.heytool.com

/www/html/www.heytool.com

2

bbs.heytool.com

/www/html/bbs.heytool.com

修改nginx设置文件：

# vi nginx.conf

usernobody nobody; #运行nginx的所属组和所有者

worker_processes2;#开启两个nginx事情历程,一般几个CPU焦点就写几

error_loglogs/error.lognotice;#错误日志路径

pidlogs/nginx.pid;# pid路径

events {

worker_connections1024; #一个历程能同时处理惩罚1024个请求

}

http {

includemime.types;

default_typeapplication/octet-stream;

log_formatmain‘$remote_addr –$remote_user [$time_local] “$request” ‘

‘$status $body_bytes_sent “$http_referer” ‘

‘”$http_user_agent” “$http_x_forwarded_for”‘;

access_loglogs/access.logmain;#默认会见日志路径

sendfileon;

keepalive_timeout65; # keepalive超市时间

#开始设置一个域名,一个server设置段一般对应一个域名

server {

listen80; #

#在本机所有ip上监听80,也可以写为192.168.1.202:80,这样的话,就只监听192.168.1.202上的80口

server_namewww.heytool.com; #域名

root/www/html/www.heytool.com;#站点根目次（措施目次）

indexindex.html index.htm; #索引文件

location / { #可以有多个location

root/www/html/www.heytool.com;#站点根目次（措施目次）

}

error_page500 502 503504/50x.html;

#界说错误页面,假如是500错误,则把站点根目次下的50x.html返回给用户

location = /50x.html {

root/www/html/www.heytool.com;

}

}

#开始设置站点bbs.heytool.com

server {

listen80;

server_namebbs.heytool.com;

root/www/html/bbs.heytool.com;

indexindex.html index.htm; #索引文件

location / {

root/www/html/bbs.heytool.com;

}

error_page500 502 503504/50x.html;

location = /50x.html {

root/www/html/bbs.heytool.com;

}

}

}

Nginx启动封锁

# /usr/local/nginx-1.0.6/sbin/nginx//启动nginx

# /usr/local/nginx-1.0.6/sbin/nginx –t //测试nginx设置文件的精确性

# /usr/local/nginx-1.0.6/sbin/nginx –s reload //重载nginx

# /usr/local/nginx-1.0.6/sbin/nginx –s stop //封锁nginx

测试

建设测试站点

# mkdir –p /www/html/www.heytool.com

# mkdir –p /www/html/bbs.heytool.com

# echo “www.heytool.com” >/www/html/www.heytool.com/index.html

# echo “bbs.heytool.com” >/www/html/bbs.heytool.com/index.html

启动nginx

# /usr/local/nginx-1.0.6/sbin/nginx –t//看到ok和successful,说明设置文件没问题

nginx: the configuration file /usr/local/nginx-1.0.6/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx-1.0.6/conf/nginx.conf test is successful

# /usr/local/nginx-1.0.6/sbin/nginx

绑定hosts,测试

把两个域名指向192.168.1.202

192.168.1.202www.heytool.com

192.168.1.202bbs.heytool.com

打开www.heytool.com,如下图：

打开bbs.heytool.com,如下图：

完毕！！！！
