【linux】CentOS7 升级sqlite3

1、yum remove sqlite3（基本可以不用，后面是直接覆盖的方式）
2、下载安装包
sqlite3下载地址：https://www.sqlite.org/download.html
wget下载:

wget -O sqlite-3350500.tar.gz   https://www.sqlite.org/2021/sqlite-autoconf-3350500.tar.gz

#-O 另存为名为sqlite-3350500.tar.gz文件

3、解压并安装（依次执行下面命令）：

#1.解压包
[root@localhost opt]#tar -zxvf sqlite-3350500.tgz.gz  #解压

#2.进入文件包
[root@localhost opt]#cd sqlite-3350500                     #进入文件包

[root@localhost sqlite-3350500]# ls
aclocal.m4     config.sub    install-sh     Makefile.am        README.txt  sqlite3.c     sqlite3.pc       sqlite3-sqlite3.o
compile        configure     libsqlite3.la  Makefile.fallback  Replace.cs  sqlite3ext.h  sqlite3.pc.in    tea
config.guess   configure.ac  libtool        Makefile.in        shell.c     sqlite3.h     sqlite3.rc
config.log     depcomp       ltmain.sh      Makefile.msc       sqlite3     sqlite3.lo    sqlite3rc.h
config.status  INSTALL       Makefile       missing            sqlite3.1   sqlite3.o     sqlite3-shell.o

#3.检测安装路径
[root@localhost sqlite-3350500]# ./configure --prefix=/usr/local/sqlite3

#4编译及安装
[root@localhost sqlite-3350500]#make && make install

4.查看是否安装成功

ls -l /usr/local/sqlite3/lib/*sqlite*
ls -l /usr/local/sqlite3/include/*sqlite*

5.替换系统中旧的sqlite

[root@localhost ~]# mv /usr/bin/sqlite3  /usr/bin/sqlite3_old
[root@localhost ~]# ln -s /usr/local/sqlite3/bin/sqlite3   /usr/bin/sqlite3
[root@localhost ~]# echo "/usr/local/sqlite3/lib" > /etc/ld.so.conf.d/sqlite3.conf
[root@localhost ~]# ldconfig

6.检测版本

[root@localhost ~]# sqlite3
SQLite version 3.35.5 2021-04-19 18:32:05
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.

若是python django 还是提示SQLite版本低

设置开机自启动执行，可以将下面的export语句写入 ~/.bashrc 文件中，如果如果你想立即生效，可以执行source ~/.bashrc 将在每次启动终端时执行

#加入环境变量
[root@localhost ~]# export LD_LIBRARY_PATH="/usr/local/sqlite3/lib"

#重新加载
[root@localhost ~]#source ~/.bashrc

还是不行

cd /tmp
wget https://www.sqlite.org/2019/sqlite-autoconf-3280000.tar.gz
tar xvf sqlite-autoconf-3280000.tar.gz
mv /usr/bin/sqlite3 /usr/bin/sqlite3.7
cp /tmp/sqlite-autoconf-3280000/sqlite3 /usr/bin/sqlite3
cp /tmp/sqlite-autoconf-3280000/.libs/libsqlite3.so.0.8.6 /usr/lib64/libsqlite3.so.0.8.6
cp /tmp/sqlite-autoconf-3280000/.libs/libsqlite3.so.0 /usr/lib64/libsqlite3.so.0

配置Python环境

从新编译python3, 唯一的区别是，在编译时略有不同。

原来的编译过程：

1 cd /usr/local/src/Python-3.6.4
2 ./configure --prefix=/usr/local/python3
3 make && make install

修改为

cd /usr/local/src/Python-3.6.4
LD_RUN_PATH=/usr/local/sqlite3/lib ./configure LDFLAGS="-L/usr/local/sqlite3/lib" CPPFLAGS="-I/usr/local/sqlite3/include"  --prefix=/usr/local/python3
LD_RUN_PATH=/usr/local/sqlite3/lib make
make && make install

特别注意:

LD_RUN_PATH=/usr/local/sqlite3/lib 此路径是安装sqlite3里文件夹lib路径
