安装配置tengine，

安装tengine

1、依赖gcc  openssl-devel  pcre-devel  zlib-devel

安装：yum install gcc openssl-devel pcre-devel zlib-devel

2、解压tengine压缩包，并进入目录；

3、./configure --prefix=/usr/tengine

4、make && make install

5、将编译完成的tengine作为Linux的系统service进行管理，需要编写一个脚本，将其加入/etc/init.d目录下。

脚本名为nginx。内容如下：

#!/bin/bash
#
# chkconfig: - 85 15
# description: nginx is a World Wide Web server. It is used to serve
# 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/tengine/sbin/nginx"
prog=$(basename $nginx)
 
NGINX_CONF_FILE="/usr/tengine/conf/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' -`
#   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: "
#  -HUP是nginx平滑重启参数  
    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 2
esac

执行命令 chmod 755 nginx

6、service nginx start

7、chkconfig --add nginx

chkconfig --list nginx //查看nginx服务状态

chkconfig nginx on //开机自启

配置tengine

/etc/tengine/conf

worker_processes 进程数，与CPU核数相等

events下的worker_connection  一个进程最大支持的并发数

虚拟主机的三种方法：

1、基于ip的虚拟主机，一块主机网卡绑定多个IP地址。

一个网卡可以绑定多个虚拟IP

# ifconfig eth0:1 192.168.143.139 netmask 255.255.255.0

# ifconfig eth0:1 down  停掉

server
{
    listen 192.168.143.132:80;
    server_name www.abc.com;
}

server
{
    listen 192.168.143.139:80;
    server_name www.abc.com;
}

2、基于域名的虚拟主机（servername）

server
{
    listen 80;
    server_name www.abc.com;
}

server
{
    listen 80;
    server_name www.bcd.com;
}

3、基于端口的虚拟主机

server
{
    listen 80;
    server_name www.abc.com;
}

server
{
    listen 8080;
    server_name www.abc.com;
}
