cd /usr/local/tomcat1/webapps/ROOT/
tar -zxvf nginx-1.14.2.tar.gz -C /usr/local
一、Linux配置Nginx
一、下載Nginx
方式1:從http://nginx.org/en/download.html上下載穩定版,解壓安裝

方式2:直接在Linux上用命令下載: wget http://nginx.org/download/nginx-1.10.2.tar.gz
-bash: wget: command not found
安裝wget:
yum -y install wget
再執行下載nginx
二、解壓安裝包&重命名
tar -zxvf nginx-1.14.2.tar.gz -C /usr/local
mv nginx-1.14.2 nginx
三、編譯
1、cd 到nginx目錄下

2、安裝相關組件
yum install -y pcre pcre-develyum install -y zlib zlib-develyum install -y openssl openssl-devel

這是提示缺少c++環境 ,用 yum install gcc-c++ 安裝一下,再執行 ./configure,然后又報錯了:

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using –without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using –with-pcre= option.
沒裝偽靜態模塊需要pcre庫
解決方法:
yum install -y pcre pcre-devel
還有可能出現:
錯誤提示:./configure: error: the HTTP cache module requires md5 functions
from 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.
解決辦法:
yum -y install openssl openssl-devel
最后 ./configure

執行make 編譯:

然后:make install 報錯:

問題原因: 直接把安裝包重命名成nginx了,安裝文件沒有路徑了。
解決辦法如下:
刪除nginx 文件夾
rm -rf nginx
重新解決源碼
tar -zxvf nginx-1.10.2.tar.gz
cd /usr/local/nginx-1.10.2
生成Makefile文件
./configure --prefix=/usr/local/nginx
編譯源碼
make
安裝
make install
這里不必要太糾結,只要 /usr/local/ 下出現了 /nagix文件就ok,進入 cd /usr/local/nginx/sbin 下,啟動 ./nginx
問題1:出現端口占用,nginx一般是80端口,要么把其他的kill掉,要么更改nginx的端口
1、kill掉其他的之前,要知道哪個占用了:用 lsof -i:80可以查看,這里是之前的lamp占用了

2、我們可以修改nginx自身的監聽端口,vi /usr/local/nginx/conf/nginx.conf ,將listen 80,改為自己要的就行,我們這里改81
- server {
- listen 80;
- server_name localhost;
- #charset koi8-r;
- #access_log logs/host.access.log main;
- location / {
- root html;
- index index.html index.htm;
- }
之后進入我們的ip:81就可以訪問:

二、Linux配置Tomcat
1、下載
下載地址:https://tomcat.apache.org/download-90.cgi
這里我們用tomcat 9 吧,下載后,一樣放到 /usr/local 下,解壓兩份,一份作為 tomcat1 , 一份為 tomcat 2 這兩份,用來做負載均衡
解壓: tar -zxvf apache-tomcat-9.0.13.tar.gz -C /usr/local
重命名: mv apache-tomcat-9.0.13 tomcat1

2、配置:
修改其中一個tomcat2 的端口信息,tomcat1則不需要修改
cd /usr/local/tomcat2/conf
vi server.xml
改以下三個端口為:8006,8081,8099
- <Server port="8005" shutdown="SHUTDOWN">
- <Connector port="8080" protocol="HTTP/1.1"
- <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
3、分別更改兩個 tomcat下默認的jsp頁面
cd /usr/local/tomcat1/webapps/ROOT/
vi index.jsp
在body中添加一行html 代碼,用於區分是哪個tomcat下的頁面。

4、啟動兩個tomcat

cd /usr/local/tomcat1/bin
./startup.sh
打開本地的ip:8080和ip:8081可以看到,兩個頁面都有提示信息:
但是8080 被占用,我們用8081和8082:8081

8082

這樣,就是安裝成功啦!
三、Nginx配置Tomcat負載均衡
1、安裝好nginx的情況下
2、修改配置文件
cd /usr/local/nginx/conf
vi nginx.conf
添加ngnix分配策略(權重策略)
upstream dangdang.com {
server 192.168.66.129:8081 weight=1; //tomcat1 的ip和端口
server 192.168.66.129:8082 weight=1; //tomcat2 的ip和端口
}
整體文件
#user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; upstream dangdang.com { server 192.168.66.129:8081 weight=1; //tomcat1 的ip和端口 server 192.168.66.129:8082 weight=1; //tomcat2 的ip和端口 } server { listen 81; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main;
結果:一直刷新
結果1:

結果2:
