环境: CentOS 7 x86_64
1、安装jdk
|
1
|
rpm -ivh jdk-8u60-linux-x64.rpm
|
2、创建普通用户
|
1
2
|
getent group tomcat || groupadd -r tomcat
getent
passwd
tomcat ||
useradd
-r -d
/opt
-s
/bin/nologin
tomcat
|
3、下载tomcat 7

cd
/opt
wget http:
//mirrors

/apache/tomcat/tomcat-7/v7
.0.64
/bin/apache-tomcat-7
.0.64.
tar
.gz
tar
zxvf apache-tomcat-7.0.64.
tar
.gz
mv
apache-tomcat-7.0.64 tomcat01
chown
-R tomcat:tomcat tomcat01
tar
zxvf apache-tomcat-7.0.64.
tar
.gz
mv
apache-tomcat-7.0.64 tomcat02
chown
-R tomcat:tomcat tomcat02

两个实例同时监听8080端口必然会产生冲突，所以必须修改.

sed
-i
's/8080/8081/g'
/opt/tomcat01/conf/server
.xml
sed
-i
's/8005/8001/g'
/opt/tomcat01/conf/server
.xml
sed
-i
's/8080/8082/g'
/opt/tomcat02/conf/server
.xml
sed
-i
's/8005/8002/g'
/opt/tomcat02/conf/server

AJP通常用不上，这里统一关闭

|
sed
-i
'/8009/d'
/opt/tomcat01/conf/server
.xml
sed
-i
'/8009/d'
/opt/tomcat01/conf/server
.xml
|
tomcat在Linux下默认工作模式是bio,性能非常低,建议使用apr或者nio，
这里改为nio,即非阻塞IO,性能比较好。

|
sed
-i.bak
's#HTTP/1.1#org.apache.coyote.http11.Http11NioProtocol#'
/opt/tomcat01/conf/server
.xml
sed
-i.bak
's#HTTP/1.1#org.apache.coyote.http11.Http11NioProtocol#'
/opt/tomcat02/conf/server
.xml
|
（如果想起用apr模式，需要安装apr-devel、tomcat-native两个软件包，无需改配置）
3、创建启动文件

cd
/usr/lib/systemd/system
cat
>tomcat01.service <<EOF
[Unit]
Description=Apache Tomcat 7
After=network.target
[Service]
Type=oneshot
ExecStart=
/opt/tomcat01/bin/startup
.sh
ExecStop=

.sh
RemainAfterExit=
yes

EOF
|
tomcat02同理
|
1
|
sed
's/tomcat01/tomcat02/g'
tomcat01.service > tomcat02.service
|
4、启动服务
|
1

4
|
systemctl
enable
tomcat01
systemctl
enable
tomcat02
systemctl start tomcat01
systemctl start tomcat02
|
5、日志轮转
由于tomcat是作为后台服务持续运行，天长日久，日志必定会越来越大，在当初部署tomcat之时很容易忽略这个问题，否则硬盘迟早会被撑爆。
创建文件/etc/logrotate.d/tomcat，内容如下：
|
1
2
3
4
5
6
7
8
9
10
11
|
/opt/tomcat01/logs/catalina.out
/opt/tomcat02/logs/catalina.out
{
copytruncate
daily
rotate 7
missingok
notifempty
compress
create 0644 tomcat tomcat
}
|
6、查看进程
|
1
|
ps
aux |
grep
tomcat
|
附上一份nginx反向代理tomcat的配置文件

本文理论上也适用于tomcat8，未经测试。
