概述
本篇文章主要先容apache和nginx的相关设置，tomcat的相关安装设置我在前面有写过一篇，具体先容通过两种设置要领设置nginx。
apache设置
源码安装
./configure --prefix=/usr/local/apache （安装目次）
make
make install
对付2.4以上版本的apache在举办源码安装的时候有的呆板会提示缺少部门插件譬喻：apr、apr-util、pcre，需要先将这些插件安装好然后再安装apache
YUM安装
yum install httpd
进入安装目次cnf.d文件夹下面，建设一个.conf后缀的文件
touch apa.conf
vim apa.cnf
Listen 8051
<VirtualHost *:8051>
ServerAdmin [email protected]
ServerName localhost
ErrorLog '/etc/httpd/logs/app_error.log'
CustomLog '/etc/httpd/logs/app_access.log' common
ProxyPass / balancer://cluster/ stickysession=JSESSIONID|jsessionid nofailover=On lbmethod=byrequests timeout=5 maxattempts=3
ProxyPassReverse / balancer://cluster/
ProxyRequests Off
ProxyPreserveHost On
<proxy balancer://cluster>
#BalancerMember ajp://localhost:8009 route=tomcat_a
BalancerMember http://localhost:8080/Front
#BalancerMember ajp://localhost:8010 route=tomcat_b
BalancerMember http://localhost:8081/Front
</proxy>
</VirtualHost>
设置文件一开始设置了apache的端口8051，然后在最下面设置了毗连tomcat的项目端口，我这里的设置的apache和tomcat都在一台处事器上面别离利用了差异的端口，在tomcat的webapps路径下面建设了一个Front项目，项目下面存放了一个test.jsp的测试页面
cd /usr/local/tomcat1/webapps
mkdir Front
cd Front
touch test.jsp
vim test.jsp
<font color=red>testa</font><b>
同样在tomcat2中也利用同样的要领建设测试页面，可是将testa改成testb
接下来确保8051端口被启用，也可以封锁防火墙，tomcat1、tomcat2都已启动，启动要领参考前面我写的关于tomcat的文章，确保httpd也以启动，假如已经将httpd插手了启动处事，
启动http处事
service httpd start
查察处事启动状态
service httpd status
接下来在欣赏器中输入：http://localhost:8051/test.jsp
假如刷新毗连页面功效是在testa和testb之间切换，说明设置乐成。
nginx设置
源码安装
建设nginx用户组
groupadd nginx
建设nginx用户
useradd -g nginx -s /sbin/nologin nginx
安装相关插件
yum install –y make zlib-devel openssl-devel pcre-devel
解压nginx安装包
tar zxvf nginx-1.8.0.tar.gz
进入安装包
cd nginx-1.8.0
安装
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module
make && make install
单个文件设置要领
建设测试页面
cd /usr/local/tomcat1/webapps
mkdir MFront
cd MFront
touch index.jsp
vim index.jsp
<font color=red>MFronttesta</font><b>
tomcat2也同样操纵，将MFronttesta改成MFronttestb
设置文件
cd /usr/local/nginx/conf
vim nginx.conf
