Linux下 Nginx安装

系统环境：CentOS 6.5

Nginx版本：nginx-1.6.0.tar.gz

1：创建目录

# mkdir /doiido/soft

# cd /doiido/soft

2：安装Nginx所需的依赖包：

# yum -y install gcc gcc-c++ openssl openssl-devel

3：安装Nginx所需的pcre库

把pcre-8.35.tar.gz上传到/doiido/soft、

# tar zxvf pcre-8.35.tar.gz

# cd pcre-8.35/

# ./configure

# make && make install

# cd ../

4：创建www用户和组，创建相关目录，并修改权限

# /usr/sbin/groupadd www

# /usr/sbin/useradd -s /sbin/nologin -M -g www www

# mkdir -p /doiido/web/www

# chmod 777 /doiido/web/www

# chown -R www:www /doiido/web/www

# chmod g+s /doiido/web/www

# mkdir -p /doiido/web/logs

# chmod +w /doiido/web/logs

# chown -R www:www /doiido/web/logs

5：安装niginx

把nginx-1.4.2.tar.gz上传到/doiido/soft

# tar zxvf nginx-1.6.0.tar.gz

# cd nginx-1.6.0

# ./configure --user=www --group=www --prefix=/doiido/server/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-pcre=../pcre-8.35 --with-pcre-jit

# make && make install

6：修改 nginx.conf配置文件

# vi /doiido/server/nginx/conf/nginx.conf

user www www;
worker_processes 4;
error_log  /doiido/web/logs/nginx_error.log  crit;
pid logs/nginx.pid;
events{
use epoll;
worker_connections 65535;
}

测试

# /doiido/server/nginx/sbin/nginx -t

nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /opt/nginx/conf/nginx.conf test is successful

如果显示下面信息，即表示配置没问题

启动nginx服务

# /doiido/server/nginx/sbin/nginx

7：编写nginx启动脚本

# vi /etc/init.d/nginx

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /doiido/server/nginx/conf/nginx.conf
# pidfile:     /doiido/server/nginx/logs/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="/doiido/server/nginx/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/doiido/server/nginx/conf/nginx.conf"

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 $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}

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

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

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
;;
status)
rh_status
;;
*)
echo $"Usage: $0 {start|stop|status|restart|reload|configtest}"
exit 2
esac

设置权限并添加到启动服务列表中

# chmod 755 /etc/init.d/nginx

# chkconfig --add nginx

# chkconfig --level 345 nginx on

# service nginx start

8：防火墙端口开放

# /sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT

# /etc/rc.d/init.d/iptables save

至此nginx安装完毕
