概述
本篇文章主要先容apache和nginx的相關設置，tomcat的相關安裝設置我在前面有寫過一篇，具體先容通過兩種設置要領設置nginx。
apache設置
源碼安裝
./configure --prefix=/usr/local/apache （安裝目次）
make
make install
對付2.4以上版本的apache在舉辦源碼安裝的時候有的呆板會提示缺少部門插件譬喻：apr、apr-util、pcre，需要先將這些插件安裝好然后再安裝apache
YUM安裝
yum install httpd
進入安裝目次cnf.d文件夾下面，建設一個.conf后綴的文件
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>
設置文件一開始設置了apache的端口8051，然后在最下面設置了毗連tomcat的項目端口，我這里的設置的apache和tomcat都在一臺處事器上面別離利用了差異的端口，在tomcat的webapps路徑下面建設了一個Front項目，項目下面存放了一個test.jsp的測試頁面
cd /usr/local/tomcat1/webapps
mkdir Front
cd Front
touch test.jsp
vim test.jsp
<font color=red>testa</font><b>
同樣在tomcat2中也利用同樣的要領建設測試頁面，可是將testa改成testb
接下來確保8051端口被啟用，也可以封鎖防火墻，tomcat1、tomcat2都已啟動，啟動要領參考前面我寫的關于tomcat的文章，確保httpd也以啟動，假如已經將httpd插手了啟動處事，
啟動http處事
service httpd start
查察處事啟動狀態
service httpd status
接下來在欣賞器中輸入：http://localhost:8051/test.jsp
假如刷新毗連頁面功效是在testa和testb之間切換，說明設置樂成。
nginx設置
源碼安裝
建設nginx用戶組
groupadd nginx
建設nginx用戶
useradd -g nginx -s /sbin/nologin nginx
安裝相關插件
yum install –y make zlib-devel openssl-devel pcre-devel
解壓nginx安裝包
tar zxvf nginx-1.8.0.tar.gz
進入安裝包
cd nginx-1.8.0
安裝
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module
make && make install
單個文件設置要領
建設測試頁面
cd /usr/local/tomcat1/webapps
mkdir MFront
cd MFront
touch index.jsp
vim index.jsp
<font color=red>MFronttesta</font><b>
tomcat2也同樣操縱，將MFronttesta改成MFronttestb

vim nginx.conf
