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/software
cd /opt/software/
wget http://Nginx.org/download/Nginx-1.10.2.tar.gz
tar -zxvf Nginx-1.10.2.tar.gz
cd Nginx-1.10.2/
mkdir -p /var/cache/Nginx
wget https://www.openssl.org/source/openssl-1.0.2j.tar.gz
tar -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-1.0.2j 
make & make install

五、启动验证安装成功

/usr/local/Nginx/sbin/Nginx
links 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-----------------
@H_652_301@#!/bin/sh
# chkconfig: 2345 80 20
# Description: Start and Stop Nginx
# Provides: Nginx
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
NAME=Nginx
Nginx_BIN=/usr/local/Nginx/sbin/$NAME
CONFIGFILE=/usr/local/Nginx/conf/$NAME.conf
PIDFILE=/usr/local/Nginx/logs/pid/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
case "$1" in
start)
echo -n "Starting $NAME... "
if netstat -tnpl | grep -q Nginx;then
echo "$NAME (pid `pidof $NAME`) already running."
exit 1
fi
$Nginx_BIN -c $CONFIGFILE
if [ "$?" != 0 ] ; then
echo " Failed"
exit 1
else
echo " done"
fi
;;
stop)
echo -n "Stoping $NAME... "
if ! netstat -tnpl | grep -q Nginx; then
echo "$NAME is not running."
exit 1
fi
$Nginx_BIN -s stop
if [ "$?" != 0 ] ; then
echo " Failed. Use force-quit"
exit 1
else
echo " done"
fi
;;
status)
if netstat -tnpl | grep -q Nginx; then
PID=`pidof Nginx`
echo "$NAME (pid $PID) is running..."
else
echo "$NAME is stopped"
exit 0       
fi
;;
force-quit)
echo -n "Terminating $NAME... "
if ! netstat -tnpl | grep -q Nginx; then
echo "$NAME is not running."
exit 1
fi
kill `pidof $NAME`
if [ "$?" != 0 ] ; then
echo " Failed"
exit 1
else
echo " done"   
fi
;;
restart)
$SCRIPTNAME stop
sleep 1
$SCRIPTNAME start
;;
reload)                                                                                      
echo -n "Reload service $NAME... "
if netstat -tnpl | grep -q Nginx; then
$Nginx_BIN -s reload
echo " done"
else
echo "$NAME is not running,can't reload."
exit 1
fi
;;
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---------------------
