编译安装nginx并修改版本头信息—参考实例

今天做实验的时候,想起我那台yum安装的nginx+php-fpm+mysql服务器上的nginx版本有点低了,并且还要加两个第3方模块,就去nginx官网下载了最新稳定版nginx-1.0.6,好了,废话不多说看教程吧.
  系统版本: centos 5.6
  ip: 192.168.1.200
  需要的软件包:nginx-1.0.6.tar.gz Nginx-accesskey-2.0.3.tar.gz ngx_cache_purge-1.3.tar.gz(这3个包可以自己去下载,我就不提供了)

1.解压并修改nginx内核
tar zxf nginx-1.0.6.tar.gz && tar zxf Nginx-accesskey-2.0.3.tar.gz && tar zxf Nginx-accesskey-2.0.3.tar.gz
cd nginx-1.0.6
vi src/http/ngx_http_header_filter_module.c
修改ngx_http_header_filter_module.c里的
static char ngx_http_server_string[] = "Server: nginx" CRLF;
static char ngx_http_server_full_string[] = "Server: " NGINX_VER CRLF;
改成:
static char ngx_http_server_string[] = "Server: tws" CRLF;
static char ngx_http_server_full_string[] = "Server: " NGINX_VER CRLF; (这行不要去改,不然后面编译会报错,我不知道网上其他人是怎么处理的,也不知道他们到底有没有亲手试过)

再来
vi src/core/nginx.h

 
改为

2.开始编译安装nginx和第3方模块
./configure --user=nginx --group=nginx --add-module=../ngx_cache_purge-1.3 --add-module=../nginx-accesskey-2.0.3  --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --with-http_secure_link_module --with-http_random_index_module --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_perl_module --with-http_geoip_module --with-mail --with-mail_ssl_module
这是我的编译参数,当然你可以根据自己的需要来修改.

如果编译安装出现错误提示,那就你要执行下面的语句
yum -y install pcre-devel GeoIP* openssl-devel

configure完后如果没有报错,就执行
make && meke install
安装完后查看nginx的版本号和编译参数
 
我这里没有把下面编译参数截图,这个你懂的

3.让nginx随系统启动
cd /etc/rc.d/init.d
vi nginx
nginx的内容:

#!/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

start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    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 $prog -TERM
    retval=$?
    if [ $retval -eq 0 ]; then
        if [ "$CONSOLETYPE" != "serial" ]; then
           echo -en "\\033[16G"
        fi
        while rh_status_q
        do
            sleep 1
            echo -n $"."
        done
        rm -f $lockfile
    fi
    echo
    return $retval
}

restart() {
    configtest || return $?
    stop
    start
}

reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    sleep 1
    RETVAL=$?
    echo
}

configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

# Upgrade the binary with no downtime.
upgrade() {
    local pidfile="/var/run/${prog}.pid"
    local oldbin_pidfile="${pidfile}.oldbin"

configtest || return $?
    echo -n $"Staring new master $prog: "
    killproc $nginx -USR2
    sleep 1
    retval=$?
    echo 
    if [[ -f ${oldbin_pidfile} && -f ${pidfile} ]];  then
        echo -n $"Graceful shutdown of old $prog: "
        killproc -p ${oldbin_pidfile} -TERM
        sleep 1
        retval=$?
        echo 
        return 0
    else
        echo $"Something bad happened, manual intervention required, maybe restart?"
        return 1
    fi
}

case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    force-reload|upgrade) 
        rh_status_q || exit 7
        upgrade
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    status|status_q)
        rh_$1
        ;;
    condrestart|try-restart)
        rh_status_q || exit 7
        restart
        ;;
    *)
        echo $"Usage: $0 {start|stop|reload|configtest|status|force-reload|upgrade|restart}"
        exit 2
esac

然后执行
chmod a+x nginx
chkconfig --add nginx
chkconfig nginx on
service nginx start

最后执行
curl -I http://localhost
 
可以看到nginx正常运行中,好了,后面就是修改nginx.conf的事了,我就不说了.
