安装Nginx 1.2.6
1、下载Nginx
# wget http://nginx.org/download/nginx-1.2.6.tar.gz
2、解压
# tar -vzxf nginx-1.2.6.tar.gz
3、编译
# ./configure --prefix=/usr/local/nginx --pid-path=/var/run/nginx.pid --error-log-path=/var/logs/nginx/error.log --http-log-path=/var/logs/nginx/access.log --with-http_stub_status_moduleConfiguration summary  + using system PCRE library  + OpenSSL library is not used  + md5: using system crypto library  + sha1: using system crypto library  + using system zlib library  nginx path prefix: "/usr/local/nginx"  nginx binary file: "/usr/local/nginx/sbin/nginx"  nginx configuration prefix: "/usr/local/nginx/conf"  nginx configuration file: "/usr/local/nginx/conf/nginx.conf"  nginx pid file: "/var/run/nginx.pid"  nginx error log file: "/var/logs/nginx/error.log"  nginx http access log file: "/var/logs/nginx/access.log"  nginx http client request body temporary files: "client_body_temp"  nginx http proxy temporary files: "proxy_temp"  nginx http fastcgi temporary files: "fastcgi_temp"  nginx http uwsgi temporary files: "uwsgi_temp"  nginx http scgi temporary files: "scgi_temp"# make# sudo make install
4、修改配置
# sudo vim /usr/local/nginx/conf/nginx.conf
5、启动、重启、关闭

运行 prefix/sbin/nginx启动# sudo /usr/local/nginx/sbin/nginx重启配置(修改配置后使得配置生效)# sudo kill -HUP `cat /var/run/nginx.pid`或者# sudo /usr/local/nginx/sbin/nginx -s reload重启Nginx# sudo /usr/local/nginx/sbin/nginx -s reopen关闭# sudo kill `cat /var/run/nginx.pid`或者# sudo /usr/local/nginx/sbin/nginx -s quit查看版本号# /usr/local/nginx/sbin/nginx -v不运行，仅测试配置文件。nginx检查正确的语法配置并且在配置中打开指定的文件# sudo /usr/local/nginx/sbin/nginx -t查看版本号、编译版本和配置参数# /usr/local/nginx/sbin/nginx -V发送stop, quit, reopen, reload信号到主进程(版本 >= 0.7.53)# sudo /usr/local/nginx/sbin/nginx -s stop# sudo /usr/local/nginx/sbin/nginx -s quit# sudo /usr/local/nginx/sbin/nginx -s reopen# sudo /usr/local/nginx/sbin/nginx -s reload
6、安装自启动程序
下载地址：http://wiki.nginx.org/InitScriptsRed Hat Nginx Init Script：http://wiki.nginx.org/RedHatNginxInitScript下载后文件为:nginx，如下：
#!/bin/sh## nginx - this script starts and stops the nginx daemon## chkconfig:   - 85 15 # description:  Nginx is an HTTP(S) server, HTTP(S) reverse /#               proxy and IMAP/POP3 proxy server# processname: nginx# config:      /etc/nginx/nginx.conf# config:      /etc/sysconfig/nginx# pidfile:     /var/run/nginx.pid # Source function library.. /etc/rc.d/init.d/functions # Source networking configuration.. /etc/sysconfig/network # Check that networking is up.[ "$NETWORKING" = "no" ] && exit 0 nginx="/usr/sbin/nginx"prog=$(basename $nginx) NGINX_CONF_FILE="/etc/nginx/nginx.conf" [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx lockfile=/var/lock/subsys/nginx make_dirs() {   # make required directories   user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=/([^ ]*/).*//1/g' -`   if [ -z "`grep $user /etc/passwd`" ]; then       useradd -M -s /bin/nologin $user   fi   options=`$nginx -V 2>&1 | grep 'configure arguments:'`   for opt in $options; do       if [ `echo $opt | grep '.*-temp-path'` ]; then           value=`echo $opt | cut -d "=" -f 2`           if [ ! -d "$value" ]; then               # echo "creating" $value               mkdir -p $value && chown -R $user $value           fi       fi   done} start() {    [ -x $nginx ] || exit 5    [ -f $NGINX_CONF_FILE ] || exit 6    make_dirs    echo -n $"Starting $prog: "    daemon $nginx -c $NGINX_CONF_FILE    retval=$?    echo    [ $retval -eq 0 ] && touch $lockfile    return $retval} stop() {    echo -n $"Stopping $prog: "    killproc $prog -QUIT    retval=$?    echo    [ $retval -eq 0 ] && rm -f $lockfile    return $retval} restart() {    configtest || return $?    stop    sleep 1    start} reload() {    configtest || return $?    echo -n $"Reloading $prog: "    killproc $nginx -HUP    RETVAL=$?    echo} force_reload() {    restart} configtest() {  $nginx -t -c $NGINX_CONF_FILE} rh_status() {    status $prog} rh_status_q() {    rh_status >/dev/null 2>&1} case "$1" in    start)        rh_status_q && exit 0        $1        ;;    stop)        rh_status_q || exit 0        $1        ;;    restart|configtest)        $1        ;;    reload)        rh_status_q || exit 7        $1        ;;    force-reload)        force_reload        ;;    status)        rh_status        ;;    condrestart|try-restart)        rh_status_q || exit 0            ;;    *)        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"        exit 2esac


保存到/etc/init.d/nginx
# cp nginx /etc/init.d
# sudo vim /etc/init.d/nginx （修改nginx主程序路径）
**************************************************************
......
#nginx="/usr/sbin/nginx"
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)


#NGINX_CONF_FILE="/etc/nginx/nginx.conf"
NGINX_CONF_FILE="/usr/local/nginx/nginx/conf/nginx.conf"
......
**************************************************************


添加执行权限
# sudo chmod +x /etc/init.d/nginx


配置成nginx服务
# sudo chkconfig nginx on


查看配置结果
# sudo chkconfig --list nginx
nginx           0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭
7、监控Nginx并发统计
需要编译时加上--with-http_stub_status_module
修改nginx配置文件如下：
# sudo vi /usr/local/nginx/nginx/conf/nginx.conf

http {    ...    server {        listen SOME.IP.ADD.RESS;        ...        location /nginx_status {            stub_status on;            access_log   off;            #allow SOME.IP.ADD.RESS;            #deny all;        }        ...    }    ...}
# sudo yum install perl-rrdtool perl-libwww-perl.noarch
# wget http://kovyrin.net/files/mrtg/rrd_nginx.pl.txt
#!/usr/bin/perluse RRDs;use LWP::UserAgent;# define location of rrdtool databasesmy $rrd = '/opt/rrd';# define location of imagesmy $img = '/opt/rrd';# define your nginx stats URLmy $URL = "http://moviewer.com/nginx_status";my $ua = LWP::UserAgent->new(timeout => 30);my $response = $ua->request(HTTP::Request->new('GET', $URL));my $requests = 0;my $total =  0;my $reading = 0;my $writing = 0;my $waiting = 0;foreach (split(//n/, $response->content)) {  $total = $1 if (/^Active connections:/s+(/d+)/);  if (/^Reading:/s+(/d+).*Writing:/s+(/d+).*Waiting:/s+(/d+)/) {    $reading = $1;    $writing = $2;    $waiting = $3;  }  $requests = $3 if (/^/s+(/d+)/s+(/d+)/s+(/d+)/);}#print "RQ:$requests; TT:$total; RD:$reading; WR:$writing; WA:$waiting/n";# if rrdtool database doesn't exist, create itif (! -e "$rrd/nginx.rrd") {  RRDs::create "$rrd/nginx.rrd",        "-s 60",	"DS:requests:COUNTER:120:0:100000000",	"DS:total:ABSOLUTE:120:0:60000",	"DS:reading:ABSOLUTE:120:0:60000",	"DS:writing:ABSOLUTE:120:0:60000",	"DS:waiting:ABSOLUTE:120:0:60000",	"RRA:AVERAGE:0.5:1:2880",	"RRA:AVERAGE:0.5:30:672",	"RRA:AVERAGE:0.5:120:732",	"RRA:AVERAGE:0.5:720:1460";}# insert values into rrd databaseRRDs::update "$rrd/nginx.rrd",  "-t", "requests:total:reading:writing:waiting",  "N:$requests:$total:$reading:$writing:$waiting";# Generate graphsCreateGraphs("day");CreateGraphs("week");CreateGraphs("month");CreateGraphs("year");#------------------------------------------------------------------------------sub CreateGraphs($){  my $period = shift;    RRDs::graph "$img/requests-$period.png",		"-s -1$period",		"-t Requests on nginx",		"--lazy",		"-h", "150", "-w", "700",		"-l 0",		"-a", "PNG",		"-v requests/sec",		"DEF:requests=$rrd/nginx.rrd:requests:AVERAGE",		"LINE2:requests#336600:Requests",		"GPRINT:requests:MAX:  Max//: %5.1lf %S",		"GPRINT:requests:AVERAGE: Avg//: %5.1lf %S",		"GPRINT:requests:LAST: Current//: %5.1lf %Sreq/sec",		"HRULE:0#000000";  if ($ERROR = RRDs::error) {     print "$0: unable to generate $period graph: $ERROR/n";   }  RRDs::graph "$img/connections-$period.png",		"-s -1$period",		"-t Requests on nginx",		"--lazy",		"-h", "150", "-w", "700",		"-l 0",		"-a", "PNG",		"-v requests/sec",		"DEF:total=$rrd/nginx.rrd:total:AVERAGE",		"DEF:reading=$rrd/nginx.rrd:reading:AVERAGE",		"DEF:writing=$rrd/nginx.rrd:writing:AVERAGE",		"DEF:waiting=$rrd/nginx.rrd:waiting:AVERAGE",		"LINE2:total#22FF22:Total",		"GPRINT:total:LAST:   Current//: %5.1lf %S",		"GPRINT:total:MIN:  Min//: %5.1lf %S",		"GPRINT:total:AVERAGE: Avg//: %5.1lf %S",		"GPRINT:total:MAX:  Max//: %5.1lf %S//n",				"LINE2:reading#0022FF:Reading",		"GPRINT:reading:LAST: Current//: %5.1lf %S",		"GPRINT:reading:MIN:  Min//: %5.1lf %S",		"GPRINT:reading:AVERAGE: Avg//: %5.1lf %S",		"GPRINT:reading:MAX:  Max//: %5.1lf %S//n",				"LINE2:writing#FF0000:Writing",		"GPRINT:writing:LAST: Current//: %5.1lf %S",		"GPRINT:writing:MIN:  Min//: %5.1lf %S",		"GPRINT:writing:AVERAGE: Avg//: %5.1lf %S",		"GPRINT:writing:MAX:  Max//: %5.1lf %S//n",				"LINE2:waiting#00AAAA:Waiting",		"GPRINT:waiting:LAST: Current//: %5.1lf %S",		"GPRINT:waiting:MIN:  Min//: %5.1lf %S",		"GPRINT:waiting:AVERAGE: Avg//: %5.1lf %S",		"GPRINT:waiting:MAX:  Max//: %5.1lf %S//n",		"HRULE:0#000000";  if ($ERROR = RRDs::error) {     print "$0: unable to generate $period graph: $ERROR/n";   }}


该脚本会按年、月、日、周分连接数和请求数生成统计表图片


# mv rrd_nginx.pl.txt rrd_nginx.pl
添加执行权限
# chmod +x rrd_nginx.pl
# sudo vim /etc/crontab
新增
* *     * * *   root    /home/web/download/rrd_nginx.pl
或者 crontab -e
新增上面一行即可
# sudo service crond restart

8、nginx日志分隔
保存分隔脚本为：/home/web/cron/cut_nginx_logs.sh

#!/bin/bash#function:cut nginx log files for lnmp v0.5 and v0.6#author: http://lnmp.org#set the path to nginx log fileslog_files_path="/var/logs/nginx"#set nginx log files you want to cutproject_name=unknownlog_files_name=accesslog_files_dir=${log_files_path}/bck/${project_name}/$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")set the path to nginx.nginx_sbin="/etc/init.d/nginx"#############################################Please do not modify the following script #############################################mkdir -p $log_files_dir#log_files_num=${#log_files_name[@]}#cut nginx log files#for((i=0;i<$log_files_num;i++));domv ${log_files_path}/${log_files_name}.log ${log_files_dir}/${log_files_name}_$(date -d "yesterday" +"%Y%m%d")_$(date +"%Y%m%d%H%M%S").log#donekill -USR1 $(cat /var/run/nginx.pid)$nginx_sbin  force-reload
