nginx安装

安装nginx：

1、解决依赖关系

编译安装nginx需要事先需要安装开发包组"Development Tools"和 "Development Libraries"。同时，还需要专门安装pcre-devel包，openssl-devel以让其支持pcre和ssl模块；

yum -y install pcre-devel.x86_64

yum -y install openssl-devel.x86_64

2、安装

首先添加用户nginx，实现以之运行nginx服务进程：
# groupadd -r nginx
# useradd -r -g nginx nginx

接着开始编译和安装：

根据需求，需要哪些模块，选择模块去编译

./configure

  --prefix=/usr

  --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

  --pid-path=/var/run/nginx/nginx.pid 

  --lock-path=/var/lock/nginx.lock

  --user=nginx

  --group=nginx

  --with-http_ssl_module

  --with-http_flv_module 　　支持flv视频流

  --with-http_stub_status_module

  --with-http_gzip_static_module 　　#支持压缩传输

  --http-client-body-temp-path=/var/tmp/nginx/client/

  --http-proxy-temp-path=/var/tmp/nginx/proxy/

  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/       #和php结合，支持FastCGI

  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi 　　#和python相结合时使用

  --http-scgi-temp-path=/var/tmp/nginx/scgi

  --with-pcre

  --with-file-aio   #支持异步IO

说明：如果想使用nginx的perl模块，可以通过为configure脚本添加--with-http_perl_module选项来实现

make && make install

3、为nginx提供SysV init脚本:

新建文件/etc/rc.d/init.d/nginx，内容如下：
#!/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' -`
   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 2
esac

而后为此脚本赋予执行权限：
# chmod +x /etc/rc.d/init.d/nginx

添加至服务管理列表，并让其开机自动启动：
# chkconfig --add nginx
# chkconfig nginx on

而后就可以启动服务并测试了：
# service nginx start
