CentOS 7 安装Nginx 部署Tomcat集群

CentOS 7 安装Nginx

互联网的开放性成就了程序员的未来，I Love Internet！

一、安装依赖包

顺序安装依赖包：遇到【y/n】都选y回车yum install gcc*yum install pcre*yum install zlib*yum install openssl*yum install links*yum install lsb查看系统版本：lsb_release -a

二、下载安装包

进入opt目录，创建software文件夹 存放Nginx下载的安装程序

mkdir /opt/softwarecd /opt/software/wget http://nginx.org/download/nginx-1.10.2.tar.gztar -zxvf nginx-1.10.2.tar.gzcd nginx-1.10.2/mkdir -p /var/cache/nginxwget https://www.openssl.org/source/openssl-1.0.2j.tar.gztar -zxvf openssl-1.0.2j.tar.gz

四、编译 安装

cd /opt/software/nginx-1.10.2/./configure \--prefix=/usr/local/nginx\--sbin-path=/usr/sbin/nginx \--conf-path=/etc/nginx/nginx.conf \--error-log-path=/var/log/nginx/error.log \--http-log-path=/var/log/nginx/access.log \--pid-path=/var/run/nginx.pid \--lock-path=/var/run/nginx.lock \--http-client-body-temp-path=/var/cache/nginx/client_temp \--http-proxy-temp-path=/var/cache/nginx/proxy_temp \--http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp \--http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp \--http-scgi-temp-path=/var/cache/nginx/scgi_temp \--user=nobody \--group=nobody \--with-pcre \--with-http_v2_module \--with-http_ssl_module \--with-http_realip_module \--with-http_addition_module \--with-http_sub_module \--with-http_dav_module \--with-http_flv_module \--with-http_mp4_module \--with-http_gunzip_module \--with-http_gzip_static_module \--with-http_random_index_module \--with-http_secure_link_module \--with-http_stub_status_module \--with-http_auth_request_module \--with-mail \--with-mail_ssl_module \--with-file-aio \--with-ipv6 \--with-http_v2_module \--with-threads \--with-stream \--with-stream_ssl_module \--with-openssl=/opt/software/nginx-1.10.2/openssl-1.0.2jmake & make install

五、启动验证安装成功

/usr/local/nginx/sbin/nginxlinks 127.0.0.1

显示welcome to nginx！安装成功。

六、开放80访问端口

开放80端口firewall-cmd --zone=public --add-port=80/tcp --permanent重启防火墙firewall-cmd --reload关闭防火墙service firewalld stop

七、编辑启动脚本

vim /etc/init.d/nginx复制一下代码到nginx文件中--------------------开始-----------------#!/bin/sh# chkconfig:        2345 80 20# Description:        Start and Stop Nginx# Provides:        nginx# Default-Start:    2 3 4 5# Default-Stop:        0 1 6PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/binNAME=nginxNGINX_BIN=/usr/local/nginx/sbin/$NAMECONFIGFILE=/usr/local/nginx/conf/$NAME.confPIDFILE=/usr/local/nginx/logs/pid/$NAME.pidSCRIPTNAME=/etc/init.d/$NAMEcase "$1" instart)echo -n "Starting $NAME... "if netstat -tnpl | grep -q nginx;thenecho "$NAME (pid `pidof $NAME`) already running."exit 1fi$NGINX_BIN -c $CONFIGFILEif [ "$?" != 0 ] ; thenecho " failed"exit 1elseecho " done"fi;;stop)echo -n "Stoping $NAME... "if ! netstat -tnpl | grep -q nginx; thenecho "$NAME is not running."exit 1fi$NGINX_BIN -s stopif [ "$?" != 0 ] ; thenecho " failed. Use force-quit"exit 1elseecho " done"fi;;status)if netstat -tnpl | grep -q nginx; thenPID=`pidof nginx`echo "$NAME (pid $PID) is running..."elseecho "$NAME is stopped"exit 0       fi;;force-quit)echo -n "Terminating $NAME... "if ! netstat -tnpl | grep -q nginx; thenecho "$NAME is not running."exit 1fikill `pidof $NAME`if [ "$?" != 0 ] ; thenecho " failed"exit 1elseecho " done"   fi;;restart)$SCRIPTNAME stopsleep 1$SCRIPTNAME start;;reload)                                                                                      echo -n "Reload service $NAME... "if netstat -tnpl | grep -q nginx; then$NGINX_BIN -s reloadecho " done"elseecho "$NAME is not running, can't reload."exit 1fi;;configtest)echo -n "Test $NAME configure files... "$NGINX_BIN -t;;*)echo "Usage: $SCRIPTNAME {start|stop|force-quit|restart|reload|status|configtest}"exit 1;;esac-----------------结束---------------------:wq! 保存分配可执行权限chmod a+x /etc/init.d/nginx重启服务器：reboot启动service nginx start停止service nginx stop重启service nginx reconfigure查看状态service nginx status

八、配置开机启动Nginx

新增nginx.service文件vim /lib/systemd/system/nginx.service------------------内容--------------------[Unit]Description=nginx After=network.target [Service] Type=forking ExecStart=/etc/init.d/nginx start        ExecReload=/etc/init.d/nginx restart        ExecStop=/etc/init.d/nginx  stop        PrivateTmp=true [Install] WantedBy=multi-user.target------------------结束--------------------保存：wq!启用：systemctl enable nginx.service测试配置是否成功：systemctl start nginx.service查看是否启动：netstat -lntp|grep nginx

九、配置nginx.conf

重点内容根据一下内容修改nginx配置项，没有无需改动，相同无需改动.

vim /usr/local/nginx/conf/nginx.conf-------------------开始---------------------events{    use epoll;        worker_connections 51200;        multi_accept on;    }    http    {        server_names_hash_bucket_size 128;        client_header_buffer_size 32k;        large_client_header_buffers 4 32k;        client_max_body_size 50m;        sendfile on;        tcp_nopush on;        keepalive_timeout 60;        tcp_nodelay on;        fastcgi_connect_timeout 300;        fastcgi_send_timeout 300;        fastcgi_read_timeout 300;        fastcgi_buffer_size 64k;        fastcgi_buffers 4 64k;        fastcgi_busy_buffers_size 128k;        fastcgi_temp_file_write_size 256k;        gzip on;        gzip_min_length 1k;        gzip_buffers 4 16k;        gzip_http_version 1.0;        gzip_comp_level 2;        gzip_types text/plain application/x-javascript text/css application/xml;        gzip_vary on;        gzip_proxied expired no-cache no-store private auth;        gzip_disable "MSIE [1-6]\.";        server_tokens off;        log_format access '$remote_addr - $remote_user [$time_local] "$request" '        '$status $body_bytes_sent "$http_referer" '        '"$http_user_agent" $http_x_forwarded_for';        server        {        }    }-------------------结束---------------------

十、部署Tomcat集群

vim /usr/local/nginx/conf/nginx.conf-------------------开始---------------------未完待续-------------------结束---------------------
