六、安装Nginx 0.7.61
1. 安装Nginx所需的pcre库:
tar zxvf pcre-7.9.tar.gz
cd pcre-7.9/
./configure
make && make install
cd ../
2. 安装Nginx
tar zxvf nginx-0.7.61.tar.gz
cd nginx-0.7.61/
./configure --user=www --group=www --prefix=/data/nginx-0.7.61 --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../
5. 创建Nginx日志目录
mkdir -p /usr/local /nginx/logs
chmod +w /usr/local /nginx /logs
chown -R www:www /usr/local /nginx /nginx/logs
4. 创建Nginx配置文件
在/data/nginx-0.7.61/conf/目录中创建nginx.conf文件:
rm -f /data/nginx-0.7.61/conf/nginx.conf
vi /data/nginx-0.7.61/conf/nginx.conf
输入以下内容:
user www www;
worker_processes 8;
error_log /data/nginx-0.7.61/logsnginx_error.log crit;
pid /data/nginx-0.7.61/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 10240;
events
{
use epoll;
worker_connections 10240;
}
http
{
include mime.types;
default_type application/octet-stream;
#charset gb2312;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
####
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
####
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
#limit_zone crawler $binary_remote_addr 10m;
server
{
listen 80;
server_name xiaonei.mowhere.net;
index index.html index.htm index.php;
root /data/webapps/xiaonei;
#limit_conn crawler 20;
location ~ .*\.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 365d;
}
location ~ .*\.(js|css)?$
{
expires 365d;
}
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /data/nginx-0.7.61/logs/access.log access;
}
server
{
listen 80;
server_name i1.mwcdn.com;
index index.html index.htm index.php;
root /data/webapps/mwcdn;
#limit_conn crawler 20;
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 365d;
}
location ~ .*\.(js|css)?$
{
expires 365d;
}
access_log off;
}
}
5. 在/data/nginx-0.7.61/conf/目录中创建fcgi.conf文件:
vi /data/nginx-0.7.61/conf/fcgi.conf
输入以下内容:
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
6. 启动Nginx
ulimit -SHn 51200
/data/nginx-0.7.61/sbin/nginx
7. 配置开机启动
vi /etc/rc.local:
ulimit -SHn 51200
/data/php-5.2.10/sbin/php-fpm start
/data/nginx-0.7.61/sbin/nginx
8. 优化系统参数
vi /etc/sysctl.conf
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 = 2
net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535
执行sysctl -p 使之生效
9. 平滑变更Nginx配置
i. 修改nginx.conf后,检查配置文件:/data/nginx0.7.61/sbin/nginx -t
ii. 找到Nginx主进程号:ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
iii. kill -HUP Nginx主进程号
iv. 或者找到Nginx的Pid文件:kill -HUP `cat /data/nginx-0.7.61/nginx.pid`
10. 截断Nginx日志
i. 创建脚本/data/nginx-0.7.61/sbin/cut_nginx_log.sh :vi /data/nginx-0.7.61/sbin/cut_nginx_log.sh
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/data/nginx-0.7.61/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /data/nginx-0.7.61/nginx.pid`
ii. 设置crontab,每天凌晨00:00切割nginx访问日志:crontab -e
00 00 * * * /bin/bash /data/nginx-0.7.61/sbin/cut_nginx_log.sh
安装时有可能会出现:
error: the HTTP cache module requires md5 functions from OpenSSL library
此报错是因为没有安装openssl和openssl-devel
Yum install openssl openssl-devel
安装完成即可.
usr/local/nginx/sbin/nginx -t //Debug 配置文件的关键命令需要重点撑握.
