tomcat篇之tomcat結合apache中的模組proxy反代理之apache安裝

標籤：apache

前提條件

rpm -qa httpd

yum -y install pcre-devel

1、編譯安裝apr

tar xf apr-1.5.2.tar.gz

cd apr-1.5.2

./configure --prefix=/usr/local/apr

make && make install

2、編譯安裝apr-util

tar xf apr-util-1.5.4.tar.gz

cd apr-util-1.5.4

#--with-apr=PATH

#--prefix=PREFIX

./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/

make && make install

3、編譯安裝apache

tar xf httpd-2.4.18.tar.gz

cd httpd-2.4.18

./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so \ 

--enable-ssl --enable-cgi --enable-rewrite --with-zlib --enable-mpms-shared=all \

--with-mpm=event --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util \

--enable-proxy --enable-proxy-http --enable-proxy-ajp --enable-proxy-balancer \

--enable-lbmethod-heartbeat --enable-slotmem-shm --enable-slotmem-plain \

--enable-heartbeat --enable-heartmonitor --enable-watchdog

make && make install

配置apache通過mod_proxy模組與tomcat結合

要使用mod_proxy與tomcat結合，需要apache已經安裝mod_proxy、mod_proxy_http、mod_proxy_ajp和proxy_balancer_module

（實現tomcat叢集時會用到）等模組

嘗試啟動apache

/usr/local/apache/bin/httpd -k start

netstat -tunlp

發現並沒有80連接埠起來，嘗試幾遍還是啟動不來

查看httpd日誌

cat /usr/local/apache/logs/error_log發現如下錯誤：

[Tue May 17 07:10:46.572233 2016] [proxy_balancer:emerg] [pid 1434:tid 139691988010752] AH01177: Failed to lookup provider ‘shm‘ for ‘slotmem‘: is mod_slotmem_shm loaded??

根據錯誤資訊發現模組mod_slotmem_shm並沒有載入，於是修改設定檔

vim /etc/httpd/httpd.conf

#LoadModule slotmem_shm_module modules/mod_slotmem_shm.so將注釋#去掉

/usr/local/apache/bin/httpd -k start

netstat -tunlp

於是服務終於啟動上來了
