安装jdk环境

yum install gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel pcre pcre-devel expat-devel -y

解压jdk

cd /home/nameke/tools && tar -zxf jdk-8u191-linux-x64.tar.gz
mkdir -p /application && mv jdk1.8.0_191 /application/java
ls -lrth /application/

安装tomcat

cd /home/nameke/tools && tar -zxf apache-tomcat-7.0.92.tar.gz
mv apache-tomcat-7.0.92 /application/tomcat_18080
ls -lrth /application/

设置java环境变量

cat >>/etc/profile<<EOF
export JAVA_HOME=/application/java/
export JRE_HOME=/application/java/jre/
export CATALINA_HOME=/application/tomcat_18080/
export OPENSSL=/usr/local/openssl/
export PATH=$JAVA_HOME/bin:$CATALINA_HOME/bin:$OPENSSL/bin:$PATH
EOF
source /etc/profile

启动Tomcat【默认端口8080】

/application/tomcat_18080/bin/startup.sh start
netstat -antp|grep 8080
ps aux|grep java

开机自启动Tomcat

• 配置systemd文件

cat >>/usr/lib/systemd/system/tomcat_18080.service<<EOF
[Unit]
Description = Tomcat 7
Documentation = man:Tomcat(7)
Documentation = https://tomcat.apache.org/download-70.cgi
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
User = nameke
Group = nameke
#PIDFile=/application/tomcat_18080/run/tomcat_18080.pid
ExecStopPost=/bin/rm -f /application/tomcat_18080/run/tomcat_18080.pid 
ExecStart = /application/tomcat_18080/bin/startup.sh start
#ExecStop=/bin/kill -s HUP 
LimitNOFILE = 5000
#Restart=on-failure
#RestartPreventExitStatus=1
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=process
PrivateTmp=true

[Install]
WantedBy=multi-user.target
EOF

• 增加JAVA_HOME、JRE_HOME环境变量

[root@vb01 ~]# grep -A6 "CATALINA Server" /application/tomcat_18080/bin/startup.sh         
# Start Script for the CATALINA Server
# -----------------------------------------------------------------------------
export JAVA_HOME=/application/java/
export JRE_HOME=/application/java/jre/
export CATALINA_HOME=/application/tomcat_18080/
export OPENSSL=/usr/local/openssl/
export PATH=$JAVA_HOME/bin:$CATALINA_HOME/bin:$OPENSSL/bin:$PATH

• 启动Tomcat

chown -R nameke:nameke /application/
systemctl daemon-reload && source /etc/profile                                       
systemctl start tomcat_18080.service && systemctl status tomcat_18080.service
systemctl enable tomcat_18080.service
java -version && /application/tomcat_18080/bin/catalina.sh version

apr依赖包安装

cd /home/nameke/tools && tar zxf apr-1.6.3.tar.gz
cd apr-1.6.3 && ./configure --prefix=/usr/local/apr
make && make install
cd /home/nameke/tools

报错锦集

• 报错：rm: cannot remove `libtoolT': No such file or directory 安装Apr出现的问题
  • 1)编辑configure文件，在30976行查找 $RM "$cfgfile" 这个地方，用#注释掉
  • 2)在configure里面第30375行，RM='$RM -f'这里的$RM后面一定有一个空格。如果后面没有空格，直接连接减号，就依然会报错。把RM='$RM'改为RM='$RM -f'

 

• 案例1：INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:

  • 缺少apr的支持: Tomcat Native 是利用 APR 来提升Tomcat性能的本地API。Tomcat Native 这个项目可以让 Tomcat 使用 Apache 的 apr 包来处理包括文件和网络IO操作，以提升性能。

yum install apr-devel -y
cd /application/tomcat_18080/bin
tar zxf tomcat-native.tar.gz
cd /application/tomcat_18080/bin/tomcat-native-1.2.18-src/native
./configure --with-apr=/usr/local/apr --with-java-home=/application/java --prefix=/application/tomcat_18080
make && make install
cd /application/tomcat_18080/

• 案例2：OPENSSL版本问题报错

  Found OPENSSL_VERSION_NUMBER 0x1000105f (OpenSSL 1.0.1e 11 Feb 2013)
  Require OPENSSL_VERSION_NUMBER 0x1000200f or greater (1.0.2)
  configure: error: Your version of OpenSSL is not compatible with this version of tcnative

  • 解决办法：编译安装openssl

cd /home/nameke/tools && wget http://www.openssl.org/source/openssl-1.0.1.tar.gz
tar xzvf openssl-1.0.2q.tar.gz
cd cd /home/nameke/tools/openssl-1.0.2q && ./config --prefix=/usr/local/openssl
make && make install
cd /home/nameke/tools

• 案例3：INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them.

• • • 第一种：严格遵守java规范，修改对象的属性名称，要求不包含java关键字;
    • 第二种：修改EL表达式，例如"${owner.new}"可以修改为"${owner['new']}";
    • 第三种：修改tomcat属性，忽略对EL表达式的关键字检查。修改$CATALINA_BASE/conf/catalina.properties文件，添加org.apache.el.parser.SKIP_IDENTIFIER_CHECK=true选项。
