Nginx之一：Nginx的编译安装

标签：nginx nginx安装 nginx install

Nginx作为高性能的WEB服务和反向代理服务，在国内各大网站广泛应用着。

它具有如下的优点：

1.高并发连接。官方测试Nginx能够支撑5万并发连接，在实际生产环境中可支撑2-4万的并发连接

2.内存消耗少，成本低廉。支持负载均衡和反向代理，而且为开源软件

3.配置文件简单，支持URL重写规则，支持GZIP压缩，节省带宽，稳定性高，支持热部署

网上查找nginx资料都很老，更新一个最新的版本用于学习参考

1、挂载cdrom

mount /dev/cdrom /media

2、配置好yum后，安装依赖包

yum -y install gcc openssl-devel pcre-devel zlib-deve

3、创建用户+组

groupadd -r nginx
useradd -r -s /bin/balse -M -g nginx nginx

4、下载最新的nginx源码包解压后，编译

官方下载地址www.nginx.org

tar -xzvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure \
--prefix=/usr/local/nginx \
--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/ningx.lock \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_flv_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/tmp/nginx/client/ \
--http-proxy-temp-path=/var/tmp/nginx/fcgi \
--http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
--http-scgi-temp-path=/var/tmp/nginx/scgi \
--with-pcre
make
make install

5、创建启停脚本/etc/init.d/nginx
#!/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/local/nginx/sbin/nginx"
prog=$(basename $nginx)
 
NGINX_CONF_FILE="/usr/local/nginx/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: "
    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

6、所有用户增加执行权限，并加入开机启动
chmod +x /etc/init.d/nginx
chkconfig nginx on
chkconfig --list nginx

7、启动nginx

/etc/init.d/nginx restart

8、验证是否安装成功

http://localhost
