nginx+php+mysql安装 三
六、安装Nginx 0.7.611. 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：
userwww www;
worker_processes 8;
error_log/data/nginx-0.7.61/logsnginx_error.logcrit;
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_typeapplication/octet-stream;
#charsetgb2312;
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_length1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;

gzip_vary on;
#limit_zonecrawler$binary_remote_addr10m;
server
{
listen 80;
server_namexiaonei.mowhere.net;

#limit_conn crawler20;
location ~ .*\.(php|php5)?$
{

fastcgi_index index.php;
include fcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{

}
location ~ .*\.(js|css)?$
{

}
log_formataccess'$remote_addr - $remote_user [$time_local] "$request" '

'"$http_user_agent" $http_x_forwarded_for';
access_log/data/nginx-0.7.61/logs/access.logaccess;
}
server
{
listen 80;
server_namei1.mwcdn.com;

{

}
location ~ .*\.(js|css)?$
{

}
access_logoff;
}
}
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_paramGATEWAY_INTERFACECGI/1.1;
fastcgi_paramSERVER_SOFTWARE nginx;
fastcgi_paramQUERY_STRING $query_string;
fastcgi_paramREQUEST_METHOD $request_method;
fastcgi_paramCONTENT_TYPE $content_type;
fastcgi_paramCONTENT_LENGTH $content_length;
fastcgi_paramSCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_paramSCRIPT_NAME $fastcgi_script_name;
fastcgi_paramREQUEST_URI $request_uri;
fastcgi_paramDOCUMENT_URI $document_uri;
fastcgi_paramDOCUMENT_ROOT $document_root;
fastcgi_paramSERVER_PROTOCOL $server_protocol;
fastcgi_paramREMOTE_ADDR $remote_addr;
fastcgi_paramREMOTE_PORT $remote_port;
fastcgi_paramSERVER_ADDR $server_addr;
fastcgi_paramSERVER_PORT $server_port;
fastcgi_paramSERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_paramREDIRECT_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 = 102465535
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.
