Linux下 Nginx安装

浏览数：23 / 时间：2015年06月20日

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
