–with-pcre=/root/Downloads/pcre-8.38 \

–with-pcre-jit \

–with-zlib=/root/Downloads/zlib-1.2.8

# 编译安装

make && make install

七、配置自动启动服务

在bash中运行以下命令，将nginx配置为自动启动的系统服务：

vi /etc/init.d/nginx

在上述init脚本中输入并保存以下内容：

#!/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: /usr/local/nginx/conf/nginx.conf

# pidfile: /usr/local/nginx/pid/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”

lockfile=/usr/local/nginx/lock/nginx.lock

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

rh_status_q || exit 0

;;

*)

echo $”Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}”

exit 2

esac

修改脚本权限，然后设置为随系统自动启动：

mkdir -p /usr/local/nginx/pid

mkdir -p /usr/local/nginx/lock

chmod 755 /etc/init.d/nginx

chkconfig nginx on

配置环境变量：

sed -i ’80s/$/&:\/usr\/local\/nginx\/sbin/’ /etc/profile

source /etc/profile

至此，可以通过以下命令操作nginx服务：

# 启动nginx服务

service nginx start

# 停止nginx服务

service nginx stop

# 重启nginx服务

service nginx restart

# 查看nginx服务状态

service nginx status

八、开启gzip压缩

在bash中运行以下命令，为nginx开启gzip压缩功能，减少网络带宽占用：

# 配置pid文件位置

sed -i ‘9s/#pid logs\/nginx.pid;/pid pid\/nginx.pid;/’ /usr/local/nginx/conf/nginx.conf

# 启用gzip压缩

sed -i ’33s/#gzip on;/gzip on;/’ /usr/local/nginx/conf/nginx.conf

# 启用gzip压缩的小文件

sed -i ’33a\ gzip_min_length 1k;’ /usr/local/nginx/conf/nginx.conf

# gzip压缩级别

sed -i ’34a\ gzip_comp_level 2;’ /usr/local/nginx/conf/nginx.conf

# 进行压缩的文件类型

sed -i ’35a\ gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;’ /usr/local/nginx/conf/nginx.conf

# 是否在http header中添加Vary: Accept-Encoding

sed -i ’36a\ gzip_vary on;’ /usr/local/nginx/conf/nginx.conf

# 禁用IE 6 gzip

sed -i ’37a\ gzip_disable “MSIE [1-6]\\.”;’ /usr/local/nginx/conf/nginx.conf

# 为ttf、otf和svg字体启用gzip

sed -i ’38a\ gzip_types font/ttf font/otf image/svg+xml;’ /usr/local/nginx/conf/nginx.conf

# 上传文件大尺寸

sed -i ’39a\ client_max_body_size 20m;’ /usr/local/nginx/conf/nginx.conf

九、开启缓存

在bash中运行以下命令，为nginx开启静态内容缓存，减少网络带宽占用：

# 为图片文件设置缓存

sed -i ’85a\\n’ /usr/local/nginx/conf/nginx.conf

sed -i ’86a\ location ~* ^.+\\.(ico|gif|jpg|jpeg|png)$ {‘ /usr/local/nginx/conf/nginx.conf

sed -i ’87a\ access_log off;’ /usr/local/nginx/conf/nginx.conf

sed -i ’88a\ expires 30d;’ /usr/local/nginx/conf/nginx.conf

sed -i ’89a\ }’ /usr/local/nginx/conf/nginx.conf

# 为文本文件设置缓存

sed -i ’90a\’ /usr/local/nginx/conf/nginx.conf

sed -i ’91a\ location ~* ^.+\\.(css|js|txt|xml|swf|wav)$ {‘ /usr/local/nginx/conf/nginx.conf

sed -i ’92a\ access_log off;’ /usr/local/nginx/conf/nginx.conf

sed -i ’93a\ expires 24h;’ /usr/local/nginx/conf/nginx.conf

sed -i ’94a\ }’ /usr/local/nginx/conf/nginx.conf

# 为静态页面设置缓存

sed -i ’95a\\n’ /usr/local/nginx/conf/nginx.conf

sed -i ’96a\ location ~* ^.+\\.(html|htm)$ {‘ /usr/local/nginx/conf/nginx.conf

sed -i ’97a\ expires 1h;’ /usr/local/nginx/conf/nginx.conf

sed -i ’98a\ }’ /usr/local/nginx/conf/nginx.conf

# 为字体设置缓存

sed -i ’99a\’ /usr/local/nginx/conf/nginx.conf

sed -i ‘100a\ location ~* ^.+\\.(eot|ttf|otf|woff|svg)$ {‘ /usr/local/nginx/conf/nginx.conf

sed -i ‘101a\ access_log off;’ /usr/local/nginx/conf/nginx.conf

sed -i ‘102a\ expires max;’ /usr/local/nginx/conf/nginx.conf

sed -i ‘103a\ }’ /usr/local/nginx/conf/nginx.conf

十、启动服务

在bash中运行以下命令，启动nginx服务：

service nginx start
