Nginx只能处理80端口和25端口的负载均衡,既Nginx只能做邮件和web服务的负载均衡1、下载稳定版本的nginx.
2、按照如下命令安装
#检查系统路径[root@localhost usr]# pwd/usr#解压到当前路径[root@localhost usr]# tar -zxv -f nginx-1.6.2.tar.gz #删除压缩包[root@localhost usr]# rm -rf nginx-1.6.2.tar.gz #进入到解压包下[root@localhost usr]# cd nginx-1.6.2/[root@localhost nginx-1.6.2]# 查看安装时的功能模块信息 [root@localhost nginx-1.6.2]# ./configure --help #指定安装路径[root@localhost nginx-1.6.2]# ./configure --prefix=/usr/local/nginx#编译[root@localhost nginx-1.6.2]# make#安装[root@localhost nginx-1.6.2]# make install#回退到解压缩包上级目录[root@localhost usr]# cd ../#解除解压缩包[root@localhost usr]# rm nginx-1.6.2 -rf
上面安装使用默认参数进行配置,如果要自定义安装模块和安装位置可以进行如下参数配置:
[root@localhost nginx-1.6.2]# ./configure \> --prefix=/usr/local/nginx \> --sbin-path=/usr/local/nginx/sbin/nginx \> --conf-path=/usr/local/nginx/conf/nginx.conf \> --http-log-path=/usr/local/nginx/logs/access.log \> --error-log-path=/usr/local/nginx/logs/error.log \> --pid-path=/usr/local/nginx/logs/nginx.pid \> --lock-path=/usr/local/nginx/lock/nginx.lock \> --http-client-body-temp-path=/usr/local/nginx/client_body_temp \> --http-proxy-temp-path=/usr/local/nginx/proxy_temp \> --http-fastcgi-temp-path=/usr/local/nginx/fastcgi-temp \> --http-uwsgi-temp-path=/usr/local/nginx/uwsgi-temp \> --http-scgi-temp-path=/usr/local/nginx/scgi-temp \> --user=root \> --group=root \> --with-http_ssl_module \> --with-http_flv_module \> --with-http_mp4_module \> --with-http_gzip_static_module \> --with-http_stub_status_module
3、安装缺少包提示
错误提示 ./configure: error: the HTTP rewrite module requires the PCRE library.You can either disable the module by using --without-http_rewrite_moduleoption, or install the PCRE library into the system, or build the PCRE librarystatically from the source with nginx by using --with-pcre=option.解决方案[root@localhost nginx-1.6.2]# yum -y install pcre-devel
错误提示 ./configure: error: the HTTP gzip module requires the zlib library.You can either disable the module by using --without-http_gzip_moduleoption, or install the zlib library into the system, or build the zlib librarystatically from the source with nginx by using --with-zlib=option.解决方案[root@localhost nginx-1.6.2]# yum install -y zlib-devel
错误提示：./configure: error: the HTTP cache module requires md5 functionsfrom OpenSSL library. You can either disable the module by using--without-http-cache option, or install the OpenSSL library into the system,or build the OpenSSL library statically from the source with nginx by using--with-http_ssl_module --with-openssl=options.解决方案[root@localhost nginx-1.6.2]# yum -y install openssl openssl-devel
上面出现的问题是因为没有安装Nginx相应的编译工具,所以在安装时可以先执行如下命令进行安装
[root@localhost ~]# yum -y install gcc gcc-c++ autoconf automake[root@localhost ~]# yum -y install zlib zlib-devel openssl openssl-devel pcre-devel
#说明:
#zlib:Nginx提供gzip模块,需要zlib库支持#openssl:Nginx提供ssl功能#pcre:支持抵制重写rewrite功能
4、修改防火墙配置：
#修改防火墙配置：[root@localhost nginx]# vi + /etc/sysconfig/iptables#添加配置项-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT#重启防火墙
[root@localhost nginx]# service iptables restart
5、启动nginx
#方法1
[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf #方法2
[root@localhost nginx]# cd /usr/local/nginx/sbin [root@admin sbin]# ./nginx
6、监察Nginx配置文件语法
[root@localhost sbin]# ./nginx -t -c /usr/local/nginx/conf/nginx.confnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
7、查看nginx是否启动
[root@localhost nginx]# netstat -ntlp
或者
#测试端口[root@localhost nginx]# netstat –na|grep 80
#浏览器中测试http://ip:80
附录:
#查询nginx主进程号[root@localhost sbin]# ps -ef | grep nginx#停止进程[root@localhost sbin]# kill -QUIT 主进程号#快速停止[root@localhost sbin]# kill -TERM 主进程号#强制停止[root@localhost sbin]# pkill -9 nginx
Nginx服务脚本
